摘要

提出了一种评价异常高压气藏有限封闭水体能量的新方法。此方法是在广义物质平衡方程的基础之上

结合异常高压气藏的生产动态

计算出异常高压气藏有限封闭水体的水体倍数

从而对气藏的水体能量进行评价。通过对新场气田新3井的实例计算

得出有限封闭水体的水体倍数为0.0805。文章论证了此方法的可靠性和有效性。

Abstract

A new method for evaluating the energy of restricted and closed aquifer in over-pressured gas reservoirs is proposed in this paper.Based on the generalized material balance principle and in combination with performance of over-pressured gas reservoirs

this new method can be used to calculate multiple of aquifer—the ratio of aquifer volume to pore volume of gas-bearing zones—for a restricted and closed aquifer in over-pressured gas reservoirs.Then the aquifer energy can be evaluated by using the multiple of aquifer.By applying the method to the well X-3 in Xin Chang gas field

we evaluated the aquifer energy for the reservoirs based on a calculated aquifer multiple of 0.080 5 for the restricted and closed aquifer.The case study shows that this new method is reliable and effective.
