Abstract

Abstract: The CT injector head is an important part of CT unit by which CT is been deployed into or pulled out of the well.The tolerance between CT and friction block affects the working performance and durability of injector head，decide the grip reliability between CT and friction block and affects the security of CT unit directly.Starting with touch behavior between friction block and CT，based on 1 1/2 inch CT unit injector head，the thesis studies the touch stress state，found the finite element analysis model，and proceeds design of parameterising model.And then the optimum tolerance between CT and friction block is gained through analysis of finite element of various combination.

Key words: coiled tubing, injector head, friction block, tolerance, finite element
