摘　　要：位于哈萨克斯坦图尔盖盆地的阿雷斯库姆坳陷,是一个在前寒武纪变质岩和古生代碳酸盐岩基底上发展起来的裂谷型坳陷。坳陷内油气资源非常丰富,其构造特征和形成演化控制了油气的富集与分布,在平面和纵向上发育不同类型的油气藏。从坳陷中部到凸起顶端,均位于有效运移距离之内,有利于油气聚集。良好区域性盖层和输导体系的合理配置,使得油气运聚效率很高。该坳陷主要存在4种油气成藏模式,中下侏罗统岩性油气藏是下一步储量增长的主要油气藏类型。Aryskum depression locatedin Kazakhstan is a rift basin developed on the basements of Precambrian metamorphic rocks and Paleozoic carbonate rocks. This depression is very rich in oil and gas resources which enrichment and distribution are controlled by its tectonic feature and evolution. And there are different types of oil and gas reservoirs in lateral and vertical directions in it. This depression is situated within the effective scope of oil-gas migration from central depression to top of arch, favorable for oil-gas accumulation. Thanks to the sound assemblage between the regional cap rocks and the transmission systems, the oil-gas migration and accumulation are efficient in this area. Four models for oil-gas accumulation occur in Aryskum depression, among which the Lower-Middle Jurassic lithologic reservoirs are the main targets for incremental oil-gas reserves.
