笔者研究X火山岩气藏水运移规律,主要利用水体能量评价容积法、数值模拟法、动态法对水体能量进行评价,根据典型出水井水侵特征和地质情况,总结了气田产水井直线型、平方型直线-指数型三种主要水侵模式,利用数值模拟建立水侵分析预报方法,建立关键参数和气井出水时间的二元非线性关系,绘制成裂缝型底水气藏水侵分析预测图版,总结气井出水规律,从而对该复杂底水气藏未来开发趋势和潜力做出科学预测,给出攻关方向及对策。
The author studies the law of water migration in X volcanic gas reservoirs, and mainly evaluates the energy of the water body using volumetric method, numerical simulation method and dynamic method of water body energy assessment. According to the characteristics of water intrusion and geological conditions of typical outlet wells, Type linear - exponential type of three major water intrusion modes, the use of numerical simulation to establish water intrusion analysis and forecasting methods, the establishment of the key parameters and the gas well water time binary nonlinear relationship, drawn into the fractured bottom water reservoir water intrusion prediction map, Summarize the law of gas well water discharge, so as to make a scientific prediction of the future development trend and potential of this complex bottom water gas reservoir, and give the direction and countermeasures for tackling the problem.
