摘要

根据裂缝和溶洞的组合模式和连通程度袁把溶洞分成两大类。对缝洞型碳酸盐岩

油藏提出了试井解释模型，建立了相应的数学模型，并采用Laplace变换和Stehfest数值反演方

法进行求解，并分析了弹性储容比和窜流因子对压力响应的影响。

Abstract

This paper presents a well test interpretation model for
the fracture-cave type carbonate reservoir composed of matrix,
fracture and cave. The mathematical model is established and
an analytical solution is presented by using Laplace transform
and numerical Stehfest inverse method. The influence of
storativity ratio and crossflow factor on pressure response is
analyzed.
