METHOD FOR GAS PIPELINE LAYING BY METHOD OF HORIZONTAL DIRECTED DRILLING

摘要

A method for laying gas pipeline by method of horizontal directed drilling at which reaming of pilot well is performed by drawing reamers in direction opposite to direction of drilling. Polymeric pipes are used for connection in gas pipeline, at that connection is carried out through melting the ends of the pipes with following compression of those and cooling of joint obtained, and the gas pipeline is tested on leak-proofness.
