Abstract

A computational algorithm is proposed for determining the acceptable range of bottom-hole pressure based on a composite indicator diagram constructed from well test data analysis in a deformable fractured porous oil reservoir. The behavior of the curves of drawdown and buildup pressure and their derivatives are analyzed in the case of a nonlinear elastic filtration regime in a fractured porous formation. A composite indicator diagram for determining the optimal bottom-hole pressure is constructed on the basis of the pressure buildup test interpretation and the Vogel’s method.

摘要

提出了一种基于可变形裂缝性多孔油藏试井数据分析构建的复合指示图确定井底压力可接受范围的计算算法。在裂缝多孔地层中非线性弹性过滤机制的情况下，分析了压降和上升压力曲线及其导数的行为。在压力建立测试解释和Vogel's方法的基础上构建了用于确定最佳井底压力的复合指示图。
