HYDRAULIC CABLE INJECTOR AND METHOD FOR CABLE DEPLOYMENT

摘要

A hydraulic cable injector includes a first stripper assembly positioned at a first end of the hydraulic cable injector to receive a cable and provide a lower seal. A first wye joint is coupled to the first stripper assembly, and a flow tube assembly is operatively coupled to the first wye joint. A second wye joint is coupled to the flow tube assembly, and a second stripper assembly is coupled to the second wye joint and proves an upper seal. A third stripper assembly is positioned at a second end of the hydraulic cable injector for injecting the cable into a tubing and providing a tubing seal. A separator interposes the second and third stripper assemblies and defines a central pathway to feed the cable into the third stripper assembly from the second stripper assembly.

1. A hydraulic cable injector, comprising:
a first stripper assembly positioned at a first end of the hydraulic cable injector to receive a cable and provide a lower seal at the first end; a first wye joint coupled to the first stripper assembly; a flow tube assembly operatively coupled to the first wye joint and having a flow tube that receives the cable after the cable extends through the first wye joint; a second wye joint coupled to the flow tube assembly; a second stripper assembly coupled to the second wye joint and providing an upper seal, wherein the lower and upper seals prevent a first fluid from migrating past the first and second stripper assemblies, respectively; a third stripper assembly positioned at a second end of the hydraulic cable injector for injecting the cable into a tubing, the third stripper assembly providing a tubing seal that prevents a second fluid in the tubing from migrating past the third stripper assembly; and a separator interposing the second and third stripper assemblies and defining a central pathway that feeds the cable into the third stripper assembly from the second stripper assembly.
