API 5CT Standard Drill Subs With Special Buckles And Threads Customized For Market And Customer Needs

________________________________________

Product overview:

Drill Subs produced and sold by our company Huichi Petro are key components used to connect, transition or adjust the length of the drill string in oilfield drilling operations. They are adapted to different drilling depths, wellbore structures and special operation requirements by adapting to drill tools of different buckle types and specifications. By reasonably matching drill pipe subs of different lengths and specifications, the overall length of the drill string can be accurately controlled to ensure that the drill bit accurately reaches the target formation. It is widely used in drilling operations in deep wells, horizontal wells and complex formations.

Working principle:

During the drilling process, the drill pipe sub works in conjunction with other drilling tools as part of the drill string. The power equipment drives the drill string to rotate and transmits torque to the drill bit, so that the drill bit can break the rock for drilling. The drill pipe sub plays the role of connecting and adjusting the length of the drill string to ensure that the drill string can be smoothly extended to the target formation. At the same time, the drilling fluid circulates through the internal channel of the drill pipe sub, which plays the role of cooling the drill bit, carrying cuttings and stabilizing the well wall.

Core functions:

1. Thread type conversion: adapt to different API standard threads (such as NC, FH, REG, etc.) to solve the problem of mismatch of drilling tool specifications.

2. Drill string adjustment: flexibly adjust the length of the drill string, optimize the configuration of the drilling tool combination, and improve the working efficiency.

3. Power transmission: the high-rigidity structure stably transmits torque and drilling pressure to reduce energy loss.

4. Adaptation to complex working conditions: can be customized according to different drilling needs, such as adding high temperature resistance, high pressure resistance, corrosion resistance design, wear-resistant belt, changing the size of the joint, etc., to meet the operating requirements in complex drilling environments. ________________________________________

Technical parameters:

• Material: high-quality alloy steel (4145H/4140), optional surface nitriding/chrome plating treatment to extend service life.
• Specification range:

o Outer diameter (OD): 3-1/2" to 10-3/4", support non-standard customization.

o Length: 0.5 meters to 3 meters, to meet diverse connection needs.

• Buckle type standard: API standard NC, FH, REG series, compatible with special buckle type customization (such as VAM, HTD).
• Mechanical properties: tensile strength ≥965 MPa, yield strength ≥758 MPa, in line with API SPEC 7-1 specification.
• Inspection and certification: 100% ultrasonic flaw detection (UT) and magnetic particle inspection (MPI) to ensure no internal defects.

Application scenarios:

1. Conventional drilling operations: In the process of ordinary vertical wells, directional wells and horizontal wells, the drill pipe short section is used to adjust the length of the drill string to meet different drilling depths and wellbore trajectory requirements.
2. Special drilling operations: In some special drilling operations, such as small hole drilling, branch well drilling and old well sidetracking, the drill pipe short section can flexibly adjust the structure and length of the drill string according to the special requirements of the operation.
3. Completion operation: In the completion stage, the drill pipe short section is used to connect various completion tools, such as casing, screen, etc., to smoothly lower them into the well and complete the completion operation.
4. Transition connection between drill collar, drill pipe and downhole tools (such as jars and shock absorbers).
5. Drill string optimization for deep wells, ultra-deep wells and large-displacement horizontal wells.
6. Harsh operating environments such as offshore platforms and high-sulfur formations.

Product advantages:

1. Efficient compatibility: One short section has multiple uses, reducing the drill string configuration time and improving operation continuity.
2. Super durability: In view of the corrosive media in the oilfield drilling environment, the surface of the drill pipe short section has undergone special anti-corrosion treatment, such as electroplating and coating.
3. Customized service: Support special sizes, materials and surface treatments to meet personalized drilling needs.
4. Accurate dimensional accuracy: Manufactured in strict accordance with international standards and industry specifications, the dimensional accuracy is controlled within a very small range. Whether it is length, outer diameter or inner diameter, it can maintain a high degree of consistency.
