DESIGN OF RETAINER SPRING OF CORING TOOL USED IN HORIZONTAL WELL
This paper introduce SP-8100 type coring tool used in horizontal well.This tool suit for unsoiled sand and broken formation,because core container moves up with telescopic system and core gripper with slip-spider close container by hydraulic pull and mechanical lifting unit,after finishing coring.The tool’s key part is retainer spring which proven meet field work and getting design requirement.
