1、油藏数值模拟 （第十二讲）主讲人:廖新维中国石油大学（北京）课程例子右图是某一油藏A-1的构造等值图。该油藏是一个略微西倾的白垩纪砂岩油藏，构造中的最大落差大约为60ft。油层最厚的部分在B-3区域内，厚度大约为40—50ft，产层平均厚度为20ft。右图是油藏A-1的沿纵轴（西南—东北剖面）和沿东—西轴（东西剖面）的两个构造剖面。课程例子油藏A-1砂体表现出很好的油藏性质，其平均孔隙度为22%，渗透率变化范围为250mD到300mD之间。右图是通过岩心分析和试井资料分析得到的孔隙度和渗透率分布图。课程例子建立
2、如右图所示x-y直角坐标系。x轴对应西南—东北方向，y轴对应东南—西北方向。课程例子建立如右图所示的二维非均匀块中心有限差分网格示意图。左图所示是二维矩形网格系统的三维示意图。右图所示是网格近似处理后所得到的沿西—东和西南—东北方向的两个横剖面图。课程例子右图是五口井的位置。从图中可以看出每个网格块中最多只有一口井，而且这些井大致位于其所在网格块的中心，此外井块与井块没有相邻。课程例子(1,1)(2,1)(3,1)(4,1)(5,1)(6,1)(7,1)(8,1)(9,1)(10,1)(11,1)(12,1)(
