潜江盐湖构造演化及沉积充填与油气成藏

Structural Evolution and Deposinal Packing as Well as Hydrocarbon Accumulation in Qianjiang Salt Lake Basin

阐述了潜江盐湖潜江组各构造演化阶段、沉积充填对油气成藏的控制作用,指出其油气分布具有纵向厚度大、侧向运移距离短、油藏类型丰富、油藏丰度低、纵向油气分布不均衡的特点和油气近源分布、油气分区分带聚集的分布规律,旨在指导该区油气勘探。

Each stage of structural evolution and control of depositional packing to the hydrocarbon accumulation in Qianjiang Formation of Qianjiang salt-lake Basin are denoted.It is pointed out that it has the characteristics of big thickness horizontally,short migration distance laterally,many types of reservoirs,low reservoir abundance and uneven distribution of oil and gas horizontally,and the rules of near oil and gas distribution and accumulation in zones and belts are introduced.The purpose of study is to guide oil and gas exploration.
