天然裂缝油藏存在裂缝而使产层不连续 ,影响了流体的流动型式 ,不仅需要描述裂缝和致密基质的固有性质 ,而且还要精确地模拟基质与裂缝之间的相互作用。控制天然裂缝油藏开采的两个主要参数是 :①裂缝渗透率的大小和非均质性控制产能并控制水 /气流入范围 ;②被裂缝连通的基质?
The fractures in the natural fractured reservoirs cause the discontinuity of the pay zones and the fluid flow patterns. They not only need to describe the inherent properties of fractures and dense matrix, but also accurately simulate the interaction between matrix and fractures. The two main parameters controlling the exploitation of natural fractured reservoirs are: (1) the size and heterogeneity of fracture permeability to control productivity and control the inflow of water / gas; (2) the matrix to be connected by cracks
