Progress in Core Engineering Technology of Gulong Shale Oil

At present, the exploration and development of Gulong shale oil has entered the deep water zone, and significant breakthroughs have been made in the exploration of the lower oil formation. The upper oil formation has started comprehensive development. However, in order to achieve efficient production and fine development of Gulong shale oil, in-depth research and technical breakthroughs are needed in shale oil drilling, hydraulic fracturing, and lifting and drainage. This article takes the on-site testing of the core engineering technology of Gulong shale oil as the research object, elaborates on the current understanding and related research results of Gulong shale oil, and conducts in-depth analysis and research on the current problems of shale oil. The aim is to reveal the engineering technology requirements of continental sedimentary shale reservoirs and provide technical support for unconventional oil and gas extraction in China.
