摘要：
The Junggar Basin is one of the most important petroliferous superimposed basins in western China. Oil and gas discoveries made there in recent decades have confirmed its great hydrocarbon potential as a superimposed basin. Data gathered through the latest exploration breakthroughs and previous studies are used to summarize the enrichment patterns of oil and gas, analyze the characteristics of oil and gas discoveries, guide strategic selection of exploration targets, and provide theorical materials for a geological study on continental petroleum reservoirs in the basin. The result shows that the reservoir assemblages in the basin exhibit a vertical "three-story" pattern and horizontal superimposition of uplifts and depressions of different stages, areas and scales in various patterns and intensity during the multi-stage superimposition process, which results in a disparity in the accumulation and distribution of oil and gas. It also suggests that the oil and gas distribution is controlled firstly by source rocks and secondly by caprocks, faults, paleo-structures, unconformities and sedimentary facies. Four major strategic exploration targets are singled out: the mid-deep to deep layers in slope area of hydrocarbon-rich sag, the thrust belt of the southern margin, the Carboniferous of Lu-Liang uplift, and shale oil in the Middle-Lower Permian. However, finding oil and gas reservoirs in this multi-cycle tectonic basin is still a big challenge due to its complex evolution history. © 2022, OIL & GAS GEOLOGY Editorial Board.
