摘　　要：针对缝洞型碳酸盐岩油藏的储层空间特征,提出新的数值模拟方法,溶穴、裂缝、孔洞分别建立各自的离散空间,离散空间之间由流动方程控制流量,扩展了多重介质的理论模型。数值计算上用基于控制体积分的有限差分方法来离散处理,各种介质的非线性方程组通过牛顿拉夫松方法全隐式求解。计算结果与解析解对比,验证了其正确性。该模型更加适用于缝洞型油藏的数值模拟研究。A new numerical simulation method has been proposed for fractured-vuggy carbonate reservoir to establish respective discrete space for caverns,fissures and vugs.The flow rate between discrete spaces is controlled by flow equation,thus extended the theoretical model of multimedia.In numerical computation,the finite difference method based on control volume method of integral has been used to conduct discrete treatment,and the nonlinear equations of varied media are implicitly solved by using the Newton-Raphson method.The calculated results are compared with analytical solutions and verified to be justified.This model is more suitable for numerical simulation of fractured-vuggy reservoirs.
