压力系统分析住靖边气田开发中的应用-井间储层连通性判断

Application Of Pressure System Analysis Method In The Developmen Of Jingbian Gas Field——interwell Reservoir Communication Judging

在气田开发早期，如何准确有效地判断井间储层连通性一直是困扰开发工作者的技术难题，同时也是开发井有效部署的关键。本文在评价地质层位对比和地震横向预测方法的基础上，首次在靖边气田将压力系统分析用于井间储层连通性判断。在确保原始地层压力可靠的前提下，提出的“就近、局部、外延”压力系统分析判断井间储层连通性方法．经井间干扰试井和气井实际钻探结果检验是有效可靠的；同时也是非常简捷经济的。该方法在靖边气田开发井井部署中发挥了重要的作用．为实现靖边气田的高效开发提供了技术保障。

It was difficult to determine the interwell reservoir communicatioh in the early stage of oil and gas field exploitation, but is the key of development well pattern arrangement. On the base of geologic correlation and seismic lateral prediction methods, this paper firstly applied the pressure system analysis method to judge the interwell reservoir communication. The characteristic of the method is handy, partial and denotative, which make sure the accuracy of the result of interwell reservoir communication judging if the initial reservoir pressure can be obtained precisely. The method has been validated by the interference Test analysis and actual drilling result in gas wells, and is simple and economic. It is crucial for the development well pattern arrangement, and insure the successful development of Jingbian gas field.
