摘要
在Tiab提出的压裂井压降试井不用典型曲线拟合的直接综合分析技术的基础上 ,进一步提出了压裂井压力恢复试井的直接综合分析技术。该方法利用压力导数与时间双对数图上的特征点和特征直线的斜率来计算参数 ,快速、准确。同时 。
In accordance with the direct comprehensive analysis technique for pressure draw-down well testing of fractured wells advanced by Tiab, this paper further puts forward a new thinking of direct comprehensive analysis technique for pressure build-up well testing of fractured wells. This technique utilizes characteristic points and slope of characteristic straight line on log-log plot of pressure derivative vs time to calculate parameters quickly and accurately. This paper also verifies practicability and effectiveness of the technique through actual cases.
