摘要
根据四川气田的特点，建立了一种裂缝性底水气藏单井水侵研究的数值模拟模型。该模型以双孔单渗数学模型为基础，用全隐式方法对基岩和裂缝两套介质系统同时求解，具有稳定性能好、计算速度快、精度高的特点。用该模型对实际气井进行模拟计算，分析裂缝性气藏单井水侵机理，讨论气井打开程度对底水上侵的影响，这对指导现场生产和治水方案研究具有一定的参考作用。
In the light of the characteristics of Sichuan gas fields, a numerical simulation model of researching water invasion of individual well in fracture gas reservoir with bottom water is set up. Taking the mathematical model of dual porosity and single permeability as base, simultaneously evaluating the two medium systems of bed rock and fracture by total implicit method, the model is stability, fast and accuracy. Using the method to analogously compute on-the-spot gas well, analyse water invasion mechanism of individual well in fracture gas reservoir and discuss the influence of gas well penetration degree on bottom water upgoing is of certain reference for directing on-the-spot production and researching the water controlling projects.
