基于Havlena-Odeh法求取水驱气藏单井控制动态储量的简便算法

A simple method to calculate single-well dynamic reserves of water-drive gas reservoirs based on Havlena-Odeh method

水侵气藏动态储量和水侵量的计算方法很多,但是过分理想化的假设限制了方法的推广使用。提出了基于Havlena-Odeh法求取水驱气藏单井控制动态储量的简便算法。实例计算表明,本文提出的算法计算过程简单、快速,计算结果比较准确,有一定实用性。

There are a lot of methods to calculate dynamic reserves and water influx of water-drive gas reservoirs, but their applications are restricted by the over-idealized assumptions. In this paper, a simple method to calculate single-well dynamic reserves of water-drive gas reservoirs is developed on a basis of Havlena-Odeh method. According to our case calculations, this method is quick and simple in calculation, quite accurate in results and applicable.
