以濮城、文南气顶为例,采用微构造研究、沉积微相分析、小层储量评价、动态监测法、数值模拟等方法和技术对东濮凹陷气顶储量动用状况和剩余气分布情况开展研究,总结了东濮凹陷砂岩气顶气藏剩余气分布的影响因素、分布形式和类型,为气顶挖潜增效、最大限度地提高采收率提供依据。

Aiming at the Pucheng and Wennan gas cap reservoirs , this paper studies the reserve producing situation and remaining gas distribution of gas caps inDongpu depression by micro-structure research , sedimentary microfaces analysis , subzone reserve evaluation , performance analysis , reservoir simulation technology etc. It sums the influence factors of remaining gas distribution , and brings out the distribution characters and types of sandstone gas caps in Dongpu depression , which provide the evidence for tapping production potential and enhancing recovery efficiency of the gas cap reservoirs.
