2. Product Overview

The drilling equipment parts detailed in this guide cover all key components of land and offshore drilling rigs, involving 8 major categories: hoisting system parts, circulation system parts, rotation system parts, power system parts, transmission system parts, control system parts, structural parts, and auxiliary system parts. Each part is matched with accurate model information (e.g., 109505-3 lifting ring for TDS-11SA top drive, A4CSG355HD3GA/30L-VZB35F524D plunger pump, 6×19S+IWRC+EIP+sZ-φ32×2200M drilling wire rope) to ensure precise compatibility with original equipment. These parts are manufactured in strict accordance with international drilling industry standards, adopting high-strength materials (such as alloy steel, wear-resistant cast iron, and corrosion-resistant composites) and advanced processing technologies (including precision forging, heat treatment, and surface anti-corrosion treatment) to ensure long service life and stable performance in harsh drilling environments. Whether it is standard replacement parts, wearing parts, or special customized parts, they can fully meet the operational needs of different drilling scenarios, from conventional oil and gas drilling to high-temperature, high-pressure, and H2S-containing harsh environment drilling.

3. Core Function Description

3.1 Hoisting System Parts

This category includes drawworks (JC081.00; JC70D), travelling blocks (YCDG005.00; YCDG160, JYC001.00; YC315), lifting rings (109505-3; TDS-11SA), hook heads (G225; YCDG002.01), and drilling wire ropes (6×19S+IWRC+EIP+sZ-φ32×2200M; API 9A). Their core function is to provide stable hoisting force for drilling tools, casings, and other heavy loads during drilling operations—realizing lifting, lowering, and positioning of drilling equipment. For example, the drawworks controls the speed and force of hoisting through variable frequency adjustment, while the travelling block and hook head cooperate to disperse the load and ensure balanced force, preventing accidents such as load tilting and wire rope breakage.

3.2 Circulation System Parts

Key parts include degassers (1000BurgessMagnaVAC, VACU-FLO 1200 380V/50Hz), plunger pumps (A4CSG355HD3GA/30L-VZB35F524D, P11S-3R1-9A2-B00-0M0), sand pumps (6×5×12 1/4; 380/75kW, ⅡB T4, IP55), and desilters (D-RND-CMS-04-16, S-416-S). Their main function is to circulate drilling fluid in the wellbore, removing cuttings generated during drilling, cooling the drill bit, lubricating the drill string, and maintaining wellbore stability. For instance, the degasser effectively separates gas (such as natural gas and air) from drilling fluid to avoid wellbore overflow; the plunger pump provides high-pressure power for drilling fluid circulation, ensuring that drilling fluid can reach the bottom of the well smoothly under high-pressure conditions.

3.3 Rotation System Parts

This category covers rotary tables (ZP011.00; ZP205, ZP004.11.01), kelly spinners (KS1500AB), and rotating heads (DQ005.12.21.00). Their core function is to drive the drill string and drill bit to rotate at a constant speed, realizing rock breaking and drilling. The rotary table, as the core component of the rotation system, provides stable torque and rotation speed, cooperating with the kelly spinner to ensure that the drill string rotates smoothly without jamming, improving drilling efficiency and hole quality.

3.4 Power and Transmission System Parts

Including AC motor fans (YJ13A12 800kW 600V/60Hz; 600V/60Hz, YJ13A1 800kW 600V/50Hz; 380V/50Hz), variable frequency adjustable speed asynchronous motors (TB03A; 800KW; 575/600V, TB35; DJ0350002), reducers (BS-50-20, K167B-77.7-B31), and hydraulic couplings (YOTF875-25DDF). These parts are responsible for converting and transmitting power—converting the power generated by diesel engines or generators into usable power for each functional system of the drilling rig, and adjusting speed and torque according to operational needs to ensure that each part operates at the optimal working condition.

3.5 Control and Safety System Parts

Key parts include disc brake assemblies (236WCSB, 324WCB2, 224WCB2), spring type safety valves (3"×7500psi; Fig1502F/M, 3"×7500psi), and crown block anti-collision devices (31-113FB-Ⅲ()). Their main function is to ensure the safe operation of drilling equipment—preventing overloading, overpressure, and other dangerous situations. For example, the disc brake assembly can quickly brake the drawworks and hoisting system in case of emergency, avoiding accidents such as drill string falling; the spring type safety valve automatically releases pressure when the system pressure exceeds the set value, protecting the pipeline and equipment from damage.

4. Structural Features

4.1 High Strength and Wear Resistance

Most core parts (such as drilling wire ropes, lifting rings, and plunger pumps) are made of high-strength alloy steel and undergo strict heat treatment (such as quenching and tempering, carburizing) to improve their tensile strength, wear resistance, and impact resistance. For example, the 6×19S+IWRC+EIP+sZ-φ32×2200M drilling wire rope adopts IWRC (Independent Wire Rope Core) structure, which has higher tensile strength and fatigue resistance than ordinary wire ropes, and can withstand long-term heavy load hoisting operations.

4.2 Corrosion and High-Temperature Resistance

For parts used in harsh environments (such as offshore drilling and H2S-containing wells), surface anti-corrosion treatment (such as galvanizing, chrome plating, and anti-corrosion coating) is adopted to resist the corrosion of drilling fluid, seawater, and harmful gases. For example, the 3"XXH(ID2.3")-7500psi oil-based casting of gate valve is made of corrosion-resistant alloy materials, which can work stably in H2S-containing environments without corrosion and leakage.

4.3 Compact Structure and Easy Installation

All parts are designed with a compact structure, considering the limited installation space of drilling rigs, and adopting standardized connection interfaces to facilitate on-site installation, disassembly, and replacement. For example, the YDKW004.00 hydraulic slip has a modular design, which can be quickly installed and disassembled without special tools, improving maintenance efficiency.

4.4 High Stability and Reliability

The structural design of each part is optimized through finite element analysis and on-site verification to ensure stable operation under high load, high pressure, and high-speed working conditions. For example, the ZP011.00 rotary table adopts a double-bearing structure, which can effectively disperse the load, reduce vibration, and ensure stable rotation, reducing the failure rate during long-term operation.

7. On-Site Fault Maintenance Cases

The following are 4 real on-site fault maintenance cases, summarizing common fault phenomena, causes, and solutions, providing practical technical reference for on-site maintenance personnel:

Case 1: Abnormal Noise and Vibration of ZP011.00 Rotary Table

Fault Phenomenon: During drilling operation, the ZP011.00 rotary table produces obvious abnormal noise and vibration, and the rotation speed is unstable, affecting drilling efficiency.

Fault Cause: After on-site inspection, it is found that the lubricating oil of the rotary table gearbox is insufficient and deteriorated, resulting in poor lubrication between gears; at the same time, the bearing of the rotary table main shaft is worn, leading to unstable rotation.

Solution: Drain the deteriorated lubricating oil in the gearbox, clean the gearbox and filter screen, add new lubricating oil that meets the standard (model: ISO VG 320); disassemble the rotary table main shaft, replace the worn bearing, and adjust the clearance between the main shaft and the bearing; after assembly, conduct no-load test and load test to ensure that the rotary table operates smoothly without abnormal noise and vibration.

Case 2: Leakage of A4CSG355HD3GA Plunger Pump

Fault Phenomenon: During the operation of the A4CSG355HD3GA plunger pump, there is obvious oil leakage at the plunger seal, resulting in reduced system pressure and inability to meet the drilling fluid circulation requirements.

Fault Cause: The plunger seal is worn due to long-term operation, and the sealing performance is reduced; at the same time, the plunger surface has scratches, which accelerates the wear of the seal.

Solution: Shut down the pump, disassemble the plunger assembly, replace the worn plunger seal with a new original seal; polish the scratched part of the plunger surface with fine sandpaper to ensure the surface is smooth; assemble the plunger assembly, conduct pressure test, adjust the seal tightness, and ensure no oil leakage.

Case 3: Drilling Wire Rope Breakage Warning of JC081.00 Drawworks

Fault Phenomenon: During the hoisting operation of the JC081.00 drawworks, the wire rope breakage warning device is triggered, and the drawworks stops operating automatically.
