摘要
Abstract
Horizontal well drilling technology is a critical way for tight oil development. In 2013, a pilot test was carried out for horizontal well group in tight oil area in Jimusar. In view of long openhole, great displacement of horizontal section, and technical dif-ifculties such as collapse wellbore, lost circulation, low penetration rate and long drilling cycle, a technology for increasing drilling rate for tight oil in Jimusar has been preliminarily generated. It is based on analysis of formation features, optimizing the wellbore conifgura-tion, control of wellbore trajectory, optimizing drilling lfuid system, making individual drilling bits, reducing drag and torque in slim hole and ifeld application of supporting tools. As a result, the penetration rate was increased by 98.27%, and drilling cycle was shortened by 17.92%. The technology lays solid foundations for further speeding up and larger application scale of long horizontal sections for tight oil in Jimusar.关键词
