摘要： 水驱气藏地质储量和水侵量是确定气藏开发规模和开发设计的重要参数,因此如何准确计算显得非常重要。应用视地质储量法, 不需要知道水侵量的大小, 仅应用生产动态数据, 通过绘制气藏视地质储量变化曲线就可以计算地质储量, 再把计算得到的地质储量带入视地质储量计算公式可以反求水侵量的值, 计算方法简便。通过实例分析及对比验证说明该方法计算结果准确。

Abstract: Original gas in-place (OGIP) and water influx in gas pool by water drive process are the key parameters for determination of a gas pool development scale and production plan. Using apparent geologic reserves method, only production performance data are needed without water influx, the OGIP can be estimated from mapping apparent geologic reserve curves, and then the water influx can be backward calculated by putting the OGIP data into the equation for apparent geologic reserves. The case study and correlation indicate that the results given by this method are accurate and reliable.

Key words: water drive, gas pool, gas reserve, water influx, calculation, estimation
