Abstract

In this work, the transient pressure characteristics of vertical well with multi-wing complex fractures are carried out. A semi-analytical model of a complex fracture network is developed using the discrete flexible method. The mathematical model is resolved using the Laplace domain and the Stehfest inversion algorithm is used to draw the plate curves of each stage of flow in the reservoir. Based on the developed model, the sensitivity of complex fractures is analyzed and the stage of flow is identified.

具有多翼复杂裂缝的垂直压裂井的压力瞬态分析

摘要

在这项工作中，进行了具有多翼复杂裂缝的垂直井的瞬态压力特征。使用离散柔性方法建立了复杂裂缝网络的半分析模型。使用拉普拉斯（Laplace）域解析数学模型，并使用Stehfest反演算法绘制储层中每个流动阶段的板块曲线。基于已开发的模型，分析复杂裂缝的敏感性并确定流动阶段。
