摘要： 基于多孔介质中流体质点的渗流规律,对底水气藏双重不完善井的水锥突破时间进行了研究,通过数学推导,得到了水锥突破时间计算公式,该公式考虑了气藏打开程度、气水流度比、原始束缚水饱和度、残余气饱和度等影响因素。实例分析表明,底水气藏的一口生产井以定产量生产,在其它条件不变的情况下,其见水时间与气藏打开程度呈不对称凸型曲线关系。

Abstract: Based on the theory of percolation flow through porous media, a study on prediction of water breakthrough time in bottom-water gas reservoirs is presented. Through mathematical calculations, a formula to determine the time of water breakthrough in bottom-water gas wells is derived. In the formula many factors are taken into account, such as perforating degree, gas-water mobility ratio, Irreducible water saturation, residual gas saturation, etc. Case study indicates that for a gas well with constant production rate, the relationship between the time of water breakthrough and the perforating degree assumes asymmetrical convex curve.

Key words: bottom-water reservoir, water coning, water breakthrough, time, prediction
