水平井压力动态分析

本文建立了不考虑及考虑井筒储存和表皮效应影响时的均质各向异性油藏水平井的渗流数学模型，在利用特征函数、有限积分变换结合拉氏变换等方法获得了这些数学模型的解后，利用数位积分和数字反演方法作出了适用于水平井试井分析的压力及压力导数典型曲线，并导出了水平井早期和晚期流动的压降近似表达式，为术平井试井分析提供了理论依据。

Dynamic Analysis of Horizontal Well Pressure

This paper establishes the percolation mathematical models of a homogeneous anisotropic reservoir horizontal well in or without consideration of wellbore storage and skin effect. After the solution of the mathematical models have been obtained by using characteristic function ,finite integral transforms, Laplace transforms, and other methods, the pressure and pressure derivative type curve is drawn that is suitable for the horizontal well testing analysis，by using numerical integral and numerical inversion methods. The approximative expression also derived of early and late pressure drop of the horizontal well testing analysis.
