Product Overview
The High Pressure Plug Pin standard hermetic sealing logging cable signal contact pin is a universal standard spare electrical contact component specially developed for oilfield well logging and coiled tubing through-tubing intervention construction operations, fully compatible with all JEREH brand logging motorhead assembly and surface cable hanger tool assemblies, serving as the core conductive contact element to realize stable, continuous transmission of logging cable electrical measurement signals between upper surface logging instruments and downhole underground logging tool strings.
This high pressure plug pin adopts integrated integral high-pressure hermetic sealing structural design, multiple layers of built-in sealing barrier components form reliable internal pressure isolation barriers to block high-pressure wellbore fluid reverse leakage along the contact pin gap, maintaining stable internal electrical insulation performance under rated high-pressure working conditions, avoiding electrical signal short-circuit or measurement data distortion failure risks caused by wellbore fluid intrusion. The external end of the plug pin is equipped with universal industry standard 1/4-28UNF-2A external thread connection specification, realizing interchangeable quick disassembly and assembly between matching logging motorhead and cable hanger internal installation positions, convenient for on-site worn plug pin replacement maintenance operations without complicated special tool matching requirements.
The product adopts single unified standard dimensional specification: fixed outer diameter OD 0.31", uniform rated maximum safe working pressure up to 15,000psi, allowable long-term continuous construction working temperature reaches 300°F, all models adopt STD standard working condition configuration, applicable to most conventional medium-high pressure, medium-temperature oil and gas well logging construction working conditions.
The High Pressure Plug Pin has no complex internal movable friction components, spring energy storage assemblies or differential pressure release mechanisms, with extremely simplified wellsite disassembly and replacement operation flow and low routine maintenance cost; construction crews only need to screw out the old failed plug pin from the internal thread installation hole of the logging motorhead assembly or surface cable hanger, then screw the new standard high pressure plug pin into the thread hole to complete the entire contact pin replacement assembly work, no additional complicated auxiliary operation steps are required, effectively shortening on-site equipment maintenance construction time and reducing human error risks.
The standardized product lineup covers only one unified standard dimensional specification (OD 0.31"), with fixed dedicated standard 1/4-28UNF-2A external thread connection, uniform rated maximum safe working pressure of 15,000psi and uniform allowable continuous working temperature of 300°F; custom outer diameter size, thread specification and high-pressure resistance grade customization are available upon customer technical drawing submission.
