建立了裂缝性底水油藏水平井三维油水二相的数值模型。与以往不同的是,该模型应用有限元方法进行差分离散,并将油水井视为单元的边界进行处理,选用任意形状六面体(曲边)单元和等参元变换以及隐式压力和隐式饱和度交替求解的方法。该模型可用来模拟计算裂缝性油藏(带边水或底水)的直井或水平井以及直井-水平井联合井网的开发问题。本模型对一裂缝性底水油藏水平井开发过程进行模拟计算,获得了一些对实际油藏工程有用的结论。图5表1参4(陈志宏摘
A numerical model of three-dimensional oil-water two-phase in fractured bottom water reservoir horizontal well was established. Different from the past, this model uses the finite element method to carry out the differential discretization, treats the oil-water well as the boundary of the unit, and selects arbitrary hexahedron (curved edge) unit and isoparametric transformation as well as implicit pressure and implicit saturation Degree of alternating solution method. The model can be used to simulate the development of straight or horizontal wells in fractured reservoirs (with edge or bottom waters) and the development of vertical and horizontal well patterns. This model simulates the development of horizontal wells in a fractured bottom water reservoir and obtains some useful conclusions for practical reservoir engineering.
