Structured Product Description & Operational Details
1. Product Introduction
This collection covers 50+ high-demand oilfield parts spanning 7 7/8″MWB high-temperature bridge plugs, 147.62mm SHR-HP/114mm MCHR packers, SQS 7″/7-5/8″ test tools, trapezoidal threaded adapters, PPS2800/FFS-32 electronic pressure gauges, top drive hydraulic/manual valves, casing heads, cementing plugs, mud treatment equipment, and workover tools. All downhole tools adopt high-strength alloy steel and high-temperature resistant sealing materials; adapters follow API standard thread machining; electronic pressure gauges feature high-precision sensing components, ensuring zero-modification fitment and stable performance in harsh high-temperature, high-pressure downhole conditions.
2. Function Description
• Well Completion & Test Tools: 7 7/8″MWB bridge plugs realize permanent downhole zonal isolation; SHR-HP/MCHR packers seal annulus spaces at 204℃/70MPa; SQS ball seats/anchors assist well testing operations; tubing plugs and take-off tools control tubing fluid flow during workover.
• Thread Adapters & Drilling Tools: Trapezoidal threaded adapters realize seamless conversion between different drill pipe/tubing threads (PAC-B, AMMT-B); top drive integrated valves regulate high-pressure drilling fluid (15000psi); drill pipe thread gauges verify thread accuracy for safe connections.
• Wellhead & Cementing Equipment: Casing heads and flanges (BX156/BX159) provide high-pressure wellhead sealing (105MPa); cement heads, floating hoops/shoes, and rubber plugs ensure efficient cementing operations; centralizers optimize casing centering for uniform cement coverage.
• Workover & Auxiliary Tools: Coiled tubing workover tools (outer cards, locators, motors) support efficient well workover; hydraulic oscillators reduce drill string friction; brake steel belts ensure rig braking safety; submersible/sewage pumps assist on-site fluid treatment.
• Monitoring & Chemical Accessories: Electronic pressure gauges record downhole pressure data in real time; cement fluid loss reducers and anti-slump agents optimize cement slurry performance and prevent cement collapse.
3. Structural Features

Frequently Asked Questions (FAQ)
Question | Answer |
Are SHR-HP and MCHR packers suitable for all high-temperature deep wells? | These packers are designed for 204℃/70MPa high-temperature high-pressure environments, matching standard tubing/casing sizes. They are suitable for most ultra-deep wells, confirm wellbore size and temperature/pressure parameters before deployment. |
What is the service life of bridge plugs and packer sealing components? | Bridge plugs have a service life of 2200-2500 operating hours; packer sealing rings are replaced every 1500-1600 hours under high-temperature conditions. Service life shortens in highly corrosive formations. |
How to select the correct trapezoidal adapter for drill pipe/tubing connections? | Match the adapter size, thread type (PAC-B/AMMT-B), and connection diameter to your drill pipe/tubing specifications; confirm thread direction (positive/reverse) and torque rating to avoid mismatch. |
