摘要
油藏数值模拟中广泛采用的笛卡儿网格在描述地质条件复杂的油藏时存在较大的局限,特别是不能逼近裂缝复杂的边界形状。针对这一问题,研究了角点几何学在传导率计算中的应用并建立了数学模型。提出了一套以非结构网格为基础的计算传导率的方法并编写了程序,通过数值模型验证了该方法的可行性,取得了预期效果。
Cartesian grid,which is widely used in reservoir numerical simulation,has much limits in characterizing complicated reservoirs,especially cannot approximate the complicate boundary form of fractures.In order to solve this problem,this paper studies the application degree of angle point geometry in conductiviry calculation,and construct a mathematical model.It propose a set of method which calculated conductivity based on non-structural grid,and compiles program.Numerical simulation verifies the feasibility of this method.
