在油藏断层附近布井 ,必须得到较准确的断层距离。现有的现代试井解释方法中 ,断层距离这一参数的获得 ,往往是通过近似镜像反映方法得到的。但用此方法求出的断层距离误差较大。为解决这一问题 ,在近似镜像反映的基础上提出精确的镜像反映方法 ,通过对实例的模拟对比分析 ,采用精确镜像反映方法进行试井解释 ,曲线拟合程度较高 ,求得的断层距离更为精确 ,为油田开发提供可靠的依据。如果采用近似的镜像反映方法 ,其结果必须校正
In the vicinity of reservoir faults, it is necessary to obtain a more accurate fault distance. In the existing interpretation method of well testing well, the parameter of fault distance is obtained by approximate image reflection method. However, the error of fault distance calculated by this method is larger. In order to solve this problem, an accurate mirror reflection method is proposed based on the approximate mirror reflection. Through the comparative analysis of the examples and well mirror interpretation using well-mirroring method, well-curve interpretation is carried out with high degree of curve fitting. The calculated fault distance More accurate, to provide a reliable basis for oilfield development. If the approximate method of mirroring is adopted, the result must be corrected
