| 摘 要： | 以靖边气田A井区为例,利用钻井及生产动态资料,通过地质储量、动储量、泄流半径、动静储量比计算与分析,详细剖析了多层合采气藏层间动用差异及其主控因素。研究表明:靖边气田多层合采条件下层间动用极不均衡,小层动静储量比最小6.8%、最大79.8%,差异较大;气藏呈现一高多低的动用格局,马五13动用突出,其它小层动用普遍较低;相关性分析表明,层间动用差异受控于储层物性,尤其是渗透率,且小层动静储量比与渗透率呈指数密切相关。

| Abstract: | Taking Jingbian gas field A area as an example,this paper analyzes the interlayer production difference and main control factors of commingling production gas reservoir by using drilling and production dynamic data and through calculation and analysis of geological reserves,dynamic reserves,discharge radius and dynamic-static reserves ratio. The results show that the dynamic and static reserve ratio of the small layer is 6.8% minimum and 79.8% maximum in Jingbian gas field. The utilization of gas reservoir shows a pattern of one high and the rest low,the utilization of Ma 513 is prominent,and the utilization of other layers is generally low;The correlation analysis shows that the interlayer production difference is controlled by reservoir physical properties,especially permeability,which shows that the ratio of static and dynamic reserves of small layer increases exponentially with permeability. |
