Product Overview
The Surface Cable Hanger bidirectional dual-grapple logging wireline suspension & high-pressure sealing anchor is a special oilfield surface logging cable fixing tool developed for two core oilfield construction operation scenarios: coiled tubing reel logging cable anchoring and intelligent well completion wellhead cable suspension.
First application scenario: the surface cable hanger is fixedly installed on the outer end face of the coiled tubing reel, providing stable mechanical anchoring support and reliable high-pressure sealing protection for the logging cable extending from the reel into the downhole wellbore, limiting cable axial sliding displacement during reel forward/reverse rotation and well tripping movement, and blocking wellbore high-pressure fluid reverse leakage along the cable gap to protect surface logging instrument equipment.
Second application scenario: the surface cable hanger is used as a fixed cable suspension fixture at the wellhead of intelligent well completion construction wells, realizing suspended fixing and high-pressure sealing of the logging control cable at the wellhead position, providing stable cable laying support for subsequent downhole intelligent completion tool string deployment and long-term well monitoring data transmission.
The tool adopts unique dual-grapple bidirectional clamping structural design, the matched pair of grapple inserts forms bidirectional mechanical locking clamping points on the outer surface of the logging cable, which can effectively restrict the upward and downward axial displacement of the logging cable under tension load, avoid cable pulling deviation and cable core wiring loose contact failure risks caused by reel rotation and well tripping operation.
The product is equipped with dual-stage independent high-pressure sealing system composed of two core sealing components: special high-pressure resistant non-drying sealing compound and built-in high-voltage through pin. The sealing compound fills the annular gap between the cable outer sheath and the hanger inner cavity to form primary fluid blocking barrier; the internal high-voltage through pin realizes insulated sealed penetration of the cable core, forming secondary high-pressure sealing barrier, the double composite sealing structure can reliably block high-pressure wellbore fluid reverse leakage under rated 15,000psi working pressure, guaranteeing stable continuous electrical signal transmission of the logging cable during long-term construction operation.
The grapple clamping inserts are fully interchangeable and replaceable structural parts, users only need to replace the internal grapple inserts of different inner diameter specifications to realize matching adaptation with multiple different outer diameter logging cables, one single main body can be compatible with multiple cable specifications, effectively reducing customer spare parts inventory purchase and storage costs.
The standard main body size of the surface cable hanger is 2" FIG 1502, all models adopt STD standard working condition configuration, the rated maximum safe working pressure reaches 15,000psi; three standard logging cable configuration options are provided for free customer selection according to on-site construction logging tool matching requirements: single-conductor mono logging cable, three-conductor tri-logging cable, seven-conductor hepta multi-core logging cable.
The Surface Cable Hanger has no complex internal movable friction components, spring energy storage assemblies or differential pressure release mechanisms, with extremely simplified wellsite installation and disassembly operation flow and low routine maintenance cost; construction crews only need to penetrate the logging cable through the central inner cavity of the hanger, install the matched bidirectional grapple inserts to clamp the cable outer sheath, fill high-pressure sealing compound into the annular gap, and install the high-voltage through pin to complete the whole cable anchoring and sealing assembly work, then fix the whole hanger unit on the coiled tubing reel end face or wellhead base to finish installation, no additional complex auxiliary operation steps such as separate ball dropping or shear pin triggering are needed, shortening wellsite installation construction time and reducing human error risks.
The standardized product lineup covers three standard logging cable configuration options under unified 2" FIG 1502 main body size, all models adopt STD standard working condition configuration with uniform rated 15,000psi maximum working pressure; custom grapple insert inner diameter specifications, main body outer size and sealing compound high-pressure resistance grade customization are available upon customer technical drawing submission.
