1. The structure of PDC drill bit

The composite sheet of the PDC China drill bit is usually cylindrical, and a thin layer of synthetic diamond is made on the tungsten carbide substrate. When drilling, the shape of the composite sheet must be kept intact to ensure that the drill bit can operate reliably in accordance with the designed 3D geometry cutting structure.

The cutting structure of a PDC bit may seem simple, but it is usually the most complicated part of a PDC bit design. Usually, the composite pieces are arranged in rows for better cleaning of cuttings. Each row is arranged along the top of the blade, protruding downward, supporting the cutting structure and keeping it in place, while effectively connecting the cutting structure to the end of the drill string. Between the blades is a chip flute, which is a channel through which the drilling fluid washes the cuttings from the face of the drill bit during drilling.

The bit body of PDC bit is divided into carcass and rigid body. The interface of the carcass PDC bit is made of steel and transitions to tungsten carbide composite material on the outer surface. The steel body PDC drill bit is made of crude steel and then coated with hard surface material to increase corrosion resistance.

2. Ideas of PDC bit design

The PDC bit can be designed into almost infinite variable combinations, so it can be modified according to the drilling application. The demand side can design and adjust it by engineers and designers by proposing performance requirements.

The ultimate goal of designing a PDC bit mainly includes two, to increase the total footage or the ROP.

Before the design starts, we need to fully understand the drilling application, including drilling rig capacity, speed (RPM), weight on bit (WOB), flow rate (TFA), drilling tool (BHA), formation strength and hardness, and drilling distance. After collecting and analyzing this information, the previous similar execution methods and execution results should be compared and analyzed according to the drill bit database. Before proceeding to the bit design part, these empirical data and all external factors should be used to create design and performance expectations.

Up to now, Cangzhou Great Drill Bits Co.,Ltd. has to be the top material supplier of CNPC, SINOPEC, CNOOC. We have a 40,000 m² of production based in Hejian provincial development zone, Hebei, and several international advanced production lines featured in turning-milling compound, five-axis linkage, special for high-performance diamond processing, with the annual production capacity of more than 10,000 pcs.

1. The importance of diamond drill bits for rock

In the process of geological drilling and engineering exploration, diamond drill bits are widely used drilling accessories. How to improve the service life of drill bits is a problem that drill manufacturers have been considering. The method of prolonging its service life should be considered from the three aspects of the raw material, manufacturing process and operation technology of the diamond drill.

Ⅱ. How to improve the service life of diamond drill bits for rock?

1. Raw materials

Diamond drill bit manufacturers and sales purposes are closely related. If it is a technology-based enterprise pursuing quality, they will strictly control the procurement of production materials. Only high-quality raw materials can ensure that the quality of the drill bit stands out among many brands. This is also the fundamental way to improve the service life of diamond drill bits.

2. Production process

Electroplated diamond drill bits have been developed for many years, and their production process has undergone many major changes. The production processes of different manufacturers are very different. Due to their respective operations, there is currently no complete system of diamond drill production processes that have been made public. To be sure, the production process is a direct factor in determining the quality of diamond drill bits.

3. Operation technology

If the choice of drill bit is the primary reason for its service life, then the actual operation is the secondary reason. No matter how good a diamond bit is, if there is no proper operation method, not only the ideal footage efficiency cannot be achieved, but it will also affect the wear of the bit. For example, in normal drilling, if the cleaning fluid cannot circulate normally, then the bottom of the generated high-temperature and high-speed rotation of the drill bit cannot be taken out, which can easily lead to drill bit burning accidents, not to mention the service life problem.

1. The composition of oil well drill bits

The oil well clay drill bit is one of the widely used drilling bits, which has the characteristics of adapting to a wide range of formations and high drilling speed of machinery and equipment.

The oil well drill bit is composed of more than 20 parts such as cutting structure, bearing structure, locking element, oil storage seal installation and nozzle installation. The current motor is repeatedly used by the motor in the wellbore, forming the front part of the motor with greater rigidity, smaller relative discharge area, and higher relative return velocity. The upper annulus is taken to form a vortex that affects the cuttings at the front. The formation of accumulation affects the drilling speed, and further formation of the repeated fragmentation of those cuttings by the PDC drill bit, which is easy to form a mud pack of the bit remover.

2. What are the advantages of oil well drill bits?

(1) The steel ball is used to lock the roller, which can be suitable for relatively high speed.

(2) The O-ring seal adopts a wear-resistant, highly saturated nitrile rubber, which increases the cross-section of the seal ring, and adds a small sealing boss at the outer end of the seal area to improve the sealing performance.

(3) The oil well drill bit uses high-strength and high-toughness alloy teeth, which improves the ability of the teeth to resist impact and reduces the probability of tooth breakage. Soft formations are inlaid with spoon-shaped teeth.

(4) The bearing of the palm of the oil well bit is covered with a layer of hard alloy, and there is also a silver-plated layer on the roller shaft to improve the anti-bite and load-bearing capacity.

(5) The oil well drill bit uses a grease that can withstand a temperature of 250°C and has low wear, which improves the ability of the drill bit.

(6) The optimized number of teeth of the oil well bit and the equipment such as exposed teeth and alloy teeth can realize the bit cutting and speed at a larger height.

Great Drill Bits consistently adhere to the concept of industrial development to promote energy development, adhered to innovative drive, scientific development, and is one of the largest scale companies in Asia forPDC bitandTricone bit,Hole openermanufacturer.

The tricone sandstone drill bit can bear higher WOB at normal speed, and can adapt to very soft to very hard formation with different cutting structures. High strength and high toughness alloy teeth are used in the insert bit, which gives full play to the high wear resistance and excellent cutting ability of the insert bit. A new type of wear-resistant material is welded on the tooth surface of the steel tooth bit to extend the service life of the bit.

The tricone roller bit is a metal sealed rolling bearing, which can stably drill under medium and low WOB and medium and high speed, so it is an ideal choice for upper well section. Many kinds of alloy teeth, such as partial top scoop tooth, scoop tooth, wedge tooth and cone ball tooth, can be selected for the insert bit. The thickness of cladding layer and the exposed height of the teeth are increased. The bit is equipped with a variety of optional features to improve the ability to adapt to different drilling technologies and various complex formations.

1. Installation methods of tricone roller bits

When we use and install the tricone roller bits, we need to know the performance of this product so as to ensure that we will be proficient users in the future. Next are introduction to the bit and its installation methods.

(1) As the tricone roller bit is a petroleum drilling tool, we set high quality standards for it. When using it, we should pay attention to the use location as different locations may have different product effects. Also, corresponding measurements should be taken before use.

(2) The tricone roller bit is used to improve the efficiency of drilling and reduce the cost. Therefore, we also need to pay attention to its cost-effectiveness so as to ensure that its effect can be brought into full play. What’s more, we need to choose different accuracy of the bits according to different purposes.

2. How to use tricone roller bits appropriately?

(1) The product of WOB and ROP recommended by the manufacturer should be taken as the constraint condition. High WOB and ROP cannot be used at the same time.

(2) In the inclined formation, the bit with small offset, no diameter maintaining and many short teeth is often used.

(3) In case of no footage, obvious increase or decrease of pump pressure, sudden decrease of ROP and increase of torque, trip out inspection shall be conducted if there is no problem with surface equipment.

(4) If it is not a problem with the ground equipment, it is necessary to start drilling immediately to avoid dropping the toothwheel when the drilling is held up continuously.

(5) Starting from three cone bit running in drilling, do the cost calculation while drilling. As long as the cost increases at several consecutive points, trip out.

(6) Perform a drilling speed test, that is, fix the drilling pressure, change the drilling speed, or fix the drilling speed and change the drilling pressure, so that the drilling pressure and the drilling speed are appropriately matched to achieve a high drilling speed.

(7) According to the drillability grade of formation and the formation of adjacent wells, the tricone bit with high footage, high speed and normal wear is selected. In the upper soft formation (drillability grade value is less than 5), the gear milling bit with high ROP can be selected; in the deep formation (drillability grade value is more than 5), the gear inlaid bit with more footage can be selected.

(8) Use combined nozzles to improve the efficiency of rock cleaning.

(9) In order to improve the efficiency of rock breaking, the pump pressure should be increased as much as possible, the water power of bit should be increased, and the interaction between hydraulic parameters and mechanical rock breaking parameters should be brought into full play.

(10) The operation during drilling must be stable and the drilling must be even. It is strictly forbidden to lift the drill, slide the drill or stop the drill.

(11) The drilling speed should be slow to prevent sudden break. When the tricone bit is 1 simple root from the bottom of the well, the pump and the rotating bit should be turned on to fully wash the bottom cuttings to avoid blocking the nozzles with cuttings that run too quickly or to avoid the pump is turned on and the formation is blocked too violently.

(12) When the drill bit touches the bottom of the well, it should run for more than 0.5h at low drilling pressure and low drilling speed (10~30 KN, drilling speed 60 r/min). After the bottom shape is formed, the design value of drilling pressure and drilling speed can be gradually increased.

(13) The bottom of the well should be clean and free of falling objects.

At present, the market of cone bit has become standardized and orderly. The competition in roller cone bit market is developing in the direction of product differentiation, brand and after-sales service. As one of the two cornerstones of market competitiveness, the role of tricone bit technical service will be more and more obvious.

1. Stratum lithology

Because of the different lithology, hardness and rock breaking mechanism, the failure forms of roller cone bit are different. The physical and mechanical properties of formation lithology, which is common in drilling in various oilfields in China, have been measured. According to the formation lithology and record of drilling time per meter collected on site, the hardness, plasticity, brittleness, abrasiveness and drillability of formation rock are analyzed. The failure forms of tricone bit are compared to confirm whether the selection and use of roller cone bit are reasonable.

2. Well location

The mechanical properties of rocks in different positions in the crust vary greatly. The deep buried rock is in the state of multi-directional compressive stress, which makes the porosity decrease and the strength increase. Generally, the rock in the upper section is loose cemented and soft, with high bit speed and low bit pressure. Generally, the rock in the lower section is hard and abrasive, and the rotary bit has low speed, high WOB and long service time. According to the collected well location and record of drilling time per meter, the characteristics of hardness, plasticity, brittleness, abrasiveness and drillability of formation rock are analyzed, and the failure forms of cone high strength drill bits are compared to confirm whether the selection and use of cone bits are reasonable.

3. Well structure

Different wellbore structures have special requirements for the size, type and use of cone bits. For example, the inclining cone bit is required to have trimming teeth or gauge structure, and the use requires high speed and low weight on bit. The data of wellbore structure, tricone bit selection and operational parameters are collected to confirm whether the selection and use of cone bit are reasonable according to the failure form of cone bit.

4. Drilling parameters

The determination of weight on bit and rotation speed not only determines the efficiency of rock breaking, but also affects the wear of the teeth and bearings. In shallow wells and soft formations, the cone bit shears, and generally adopts high speed and low drilling pressure. In medium-hard formations, the cone bit has the comprehensive action of shearing, impact and crushing, and generally uses medium speed and medium and high weight-on-bit. In deep wells and hard formations, cone bits are mainly used for crushing and impact, generally with high weight-on-bit and low rotation speed. The reasonable selection of drilling parameters largely determines the failure mode of cone bits. The shift report and weight indicator are collected to analyze the drilling parameters and their changes, and determine the fairness of use according to the failure mode of the roller cone bit.
