Abstract: Based on the review of the exploration history of Permian shale oil in Junggar basin, the geological conditions, oil and gas accumulation mechanism and enrichment pattern of the shale oil in Jimsar sag are analyzed, the geophysical prospecting techniques obtained from previous shale oil exploration practices are systematically summarized and the direction of future shale oil deployment in Junggar basin is pointed out. The exploration practices prove that the shale oil in Jimsar sag is very typical in China’s terrestrial shale oil which is characterized by salty lake basin, multi-source mixed sedimentation, source rock-reservoir integration and scattered “sweet spot” distribution. The shale oil in the Lucaogou formation exhibits 2 occurrences such as absorbed state and free state and is considered as accumulation within source or accumulation near source. Many technological breakthroughs in shale oil exploration have been made and matched seismic prediction technologies for sweet spot and high-resolution comprehensive logging evaluation technologies have been developed. The study results show that the western part of Jimsar sag has favorable geological conditions for high yield of shale oil and should be considered as the new area for the terrestrial lacustrine shale oil exploration in Junggar basin. Based on which, a national demonstration zone for shale oil exploration and development will be established in order to provide reference and technical support for the exploration deployment of terrestrial lacustrine shale oil in China
