　　掌握流体在多孔介质中得流动规律是油藏工程领域得一个基本问题。对油藏中压力分布以及流量随时间的变化进行仔细分析和模拟能够帮我工程人员了解流体在多孔介质中得输运动态。单相渗流模型是描述多孔介质渗流过程最简单的模型,虽然理论上较为简单,该类模型常用于油气田开发早期的流动模拟计算或简化的流动分析场合。本文介绍了课题组内的2维单相渗流数值模拟器的基本原理并编程实现了计算过程。渗流方程组采用有限差分法离散,并采用Stone提出的强隐式解法求解渗流方程。数值模拟器采用MATLAB编程实现,其计算可应用与可压缩流和微可压缩流。为了验证计算结果的正确性,分别验证了时间步长内的物料守恒和累计物料守恒,显示了计算结果的正确性。
