摘要: 西湖凹陷是目前东海陆架盆地突破相对较大的凹陷,是一个具有较大勘探潜力的地区。西湖凹陷花港组具有较好的油气地质条件,存在多个油气源,以平湖组烃源岩为主,储层条件较好,发育区域性盖层。构造圈闭是西湖凹陷花港组的主要圈闭类型,以滚动背斜和挤压背斜圈闭为主,油气藏也主要为这2种类型。在对石油地质条件分析的基础上,对花港组的油气分布规律进行了分析,认为西部以油为主,东部以气为主,主要的油气分布于西湖凹陷中南部的局部构造较发育区。Abstract: The Xihu Sag with relatively great exploration breakthrough in the East China Sea shelf basin has a great exploration potential.Huagang Formation of the Xihu Sag holds good petroleum geology conditions,which has multiple hydrocarbon sources in which the main is Pinghu Formation,and good reservoirs and regional seals are well developed.Structural trap is the main trap type,such as rollover anticline and compression anticline trap,and oil-gas reservoirs are also belong to these two types.Based on the analysis of the petroleum geology and hydrocarbon distribution pattern of the Huagang Formation,it is considered that the western part mainly contains oil,while the eastern part mainly contoins gas,and the main hydrocarbon distributes in the middle and southern part of the Xihu Sag in which the structure is more locally developed.
