摘要
利用包裹体分析,确认区内存在3次成藏期,分别为东三-东二期、东营末期及馆陶-明化镇期.通过油气分布现状分析,总结出区内油气成藏主要受圈闭类型、断层活动、盖层及储层发育情况控制,建立了相应的成藏模式.不同构造带存在不同的油气成藏期次,因而油气分布在平面上及垂向上存在不均一性.葵太构造带的中深层及燕南构造带的斜坡部位应是进一步勘探的重点区域.
Abstract
Accumulation may be divided into three periods based on inclusion analysis:E3d3-E3d2,the end of E3d and N1g-N2m.Pool-forming is mainly controlled by trap type,fault activity and growth of cap and reservoir,and the pattern of pool-forming is established.There are different pool-forming stages for different structural zones,resulting in the heterogeneity of oil-and-gas distribution both laterally and vertically.The mid-deep formation in Kuitai area and the slope of Yannan area are the major potential region.
