多重介质油藏试井软件

本文基于近年来对我国现有的碳酸盐岩油气田各种渗流模式的研究,运用最优化的理论与方法(主要是多变量非线性规划的方法),提出了一套以实现压力恢复曲线的最优化拟合为目标,反求地层参数的试井资料分析方法,并编制了相应的计算机试井分析软件,其功能是用计算机自动完成试井曲线类型的识别和地层参攀的确定,考虑到为便于在油田二级指挥部或矿区大队推广使用,软件的编制特别注意照顾能在微型机上推广使用的特点。该套软件的基本功能是:能对单重介质、双重介质、裂缝性油、气藏等不同地质条件下的油、气井测试资料进行自动分析处理;准确地解释出油气藏的各项基本参数,包括:渗透率,井筒储存系数,表皮系数,流动系数,导压系数,窜流系数,弹性容量比,裂缝长度,平均油藏压力,单井控制储量,断层距离,断块形状,边界性质等。该软件是认识油(气)井和油(气)藏特性的重要工具。

WLL TEST SOFTWARE

A new method for well test analysis has been discussed in this paper. Based on the method, an interactive computeraided well test interpretation software has been developed. The basic functions of the software are its being able to analyze and process various oil/gas well testing data for single/double media automatically and interpret various reservoir basic parameters accurately. Therefore, it is an important tool for recognizing the features and behaviors of wells and reservoirs.
