摘要： 气藏物质平衡方程是气藏工程中的重要方法。气藏能量主要包括气藏岩石与束缚水的弹性能、气体弹性能与水体弹性能。涉及的关键参数有储集层与流体物性参数、气藏储量与水体规模等静态参数以及气藏平均压力与累计产出量等动态参数。这些参数均存在不确定性。基于物质平衡原理,推导出弹性水驱气藏的水体评价方程,继而对开发早期气藏水体规模进行不确定性分析。

Abstract: Material balance equation for gas reservoir is an important method in gas reservoir engineering. In gas reservoir there exist elastic energy of rock, imeducible water, gas and aquifer, which are determined by critical parameters that consist of static parameters such as reservoir and fluid quality, gas reserves, aquifer size and dynamic parameters such as average pressure and accumulative production, etc., but these parameters are of uncertainty at the early stage of gas reservoir development. This paper presents the new equation for aquifer evaluation of elastic waterflood gas reservoir derived from material balance equation and the analysis of uncertainty of aquifer size in early stage of gas reservoir de velopment.

Key words: gas reservoir, material balance equation, edge water, bottom water, uncertainty
