摘要: 通过对数值试井的地层压力与不稳定试井结合的数学模型使用径向网格求解,介绍了一种新的应用方法。利用数值试井和不稳定试井各自的优点进行优化,该方法可以利用数值试井获得地层压力随时间的变化,同时利用压力变化获得单井控制储量,利用不稳定试井的优点是可以获得单井的物性参数,并且应用该方法对塔里木克拉2 气田进行了分析。

Abstract: Through mathematical models of the numerical well testing and unstable testing by using radial grid, a new application method which optimizes the respective advantages of numerical well testing and unstable well testing is introduced. By using this method, the changes of the formation pressure by time can be obtained from numerical well test, and then controlled reserves of a single wel can be obtained from the pressure change by time. The advantage of using the unstable testing is to obtain physical parameters of a single well. The formation pressure obtained by analyzing two gas fields of Tarim Kela with this method is more in line with actual conditions.
