| 摘 要： | 在野外地质剖面研究的基础上,对柴达木盆地西部古近—新近系干柴沟组进行了详细的沉积相研究,分析了干柴沟组发育的冲积扇、河流、三角洲、扇三角洲、湖泊、湖底扇及风暴沉积等几种沉积相类型.详细分析了沉积相的平面展布特征.强调了三角洲相前缘、扇三角洲相前缘、滨浅湖滩坝、湖底扇以及碳酸盐岩沉积是西部地区干柴沟组有利的储集岩相带.根据生油岩及储油岩叠置组合关系,指出阿尔金山前地区、跃进-东柴山地区、大风山地区是有利油气聚集区带.

| Abstract: | Based on the observation of the outcrops,we studied the details of the sedimental facies in Ganchaigou Formation,and analysed the variety of sedimental facies,including alluvial-fan facies,braided stream facies,fan-delta facies,lacustrine facies,lacustrine floor fan facies and storm deposit facies.We then studied the details of the characteristics of the lateral distribution of the sedimental facies.We suggest that the favorable reservoir facies within Ganchaigou Formation in West Qaidam Basin are delta front facies,fan-delta front facies,dam-and-beach facies of the littoral and shallow lake,lacustrine floor fan facies and carbonates facies.Studies on the combination of source rocks and reservoirs show that Yuejin-Dongchaishan,Dafengshan and the front part of Arjinshan area are the most favourable areas for oil and gas accumulation. |
