物质平衡法在异常高压气藏储量估算中的应用

An Analysis of the Application of Ma -terial Balance Method to Calculating Reserves as Pressure Drop for Abnormal High Pressure Gas Reservoirs.

异常高压气藏的开发过程复杂、成本高。为了合理地开发异常高压气藏应合理地进行气藏开发动态分析,把握气田开发主动权。对近年来发展的五种动态分析方法进行了综合分析,这些方法是基于物质平衡方程得到的。最后以美国Osscem和AndersonL异常高压气藏为例,对上述方法应用效果作了对比分析,其结果可供以后开发我国大型异常高压气藏时作为参考。

The reservoir pressure of abnormal high pressure gas reservoir is higher than the corresponding hydro-static pressure,which results in the complicated exploitative process and much high cost.In order to develop abnormal high pressure gas reservoirs and analyze their production performance effectively,integrative analysis is made to some recent dynamic analysis methods in this paper.All of the methods are based on material balance equation and listed there,including Hammerlindll Single-point Adjustment Method,and Becerra-Arteaga's Pressure Curve Method.In the end,two typical abnormal high pressure gas reservoirs in America(Osscem and Anderson L)are taken for instance to an-alyze the effects of such methods.This can be used for reference to the development of domestic abnormal high pressure gas reservoirs in the future.
