系统的总结了阿南凹陷哈东洼槽成藏条件,对地层层序、构造演化、成藏要素和分布规律进行了研究。通过成藏要素的剖析,认为哈东洼槽具有良好的生储盖条件,腾一段及阿尔善组顶部均发育较好储层,以扇三角洲砂体为主;发育腾一段自生自储式储盖组合、阿尔善组自生自储式储盖组合、及阿尔善组生腾一段储的下生上储式组合。通过对哈东洼槽的油藏类型研究和陡坡带和缓坡带的油气分布特征,对哈东洼槽的油气勘探指明了方向。
This paper summarizes the accumulation conditions of the Hadong depression in the Annan depression, and studies on the stratigraphic sequence, tectonic evolution, the elements and distribution of accumulation. According to the analysis of hydrocarbon accumulation elements, it is concluded that the Haxong depression has favorable conditions for the genesis and accumulation of cap rocks, the best reservoirs are developed in the Tengyi Section and the top of the Arxian Formation, and the fan deltaic sand body is dominant. Cover combination, the Arshan Formation spontaneous self-storage reservoir cover combination, and Aershan Teng Teng a storage undergrowth reservoir combination. Through the study of the reservoir types in the Hatta depression and the distribution characteristics of oil and gas in the steep slope belt and the gentle slope belt, the direction of hydrocarbon exploration in the east and east of Haxi depression is pointed out.
