Application of Key Technologies of Expansion Pipe in Oil and Gas Well Project

摘要

As an emerging technology in the field of oil and gas well project, oil and gas well expansion pipe could maximally reduce the hole size decrease resulting from reduced catheter column of the wellbore, so as to achieve the purpose of saving costs. Meanwhile, this technology brings good news to Nerve well drilling in complicated geological condition and improvement of well structure. This article starts from the working principles of expansion pipe, and puts emphasis on the key technologies of expansion pipe and gives a detailed analysis of the application of expansion pipe technology.
