| 摘 要： | 静北潜山区主要发育北西向和北东向两组裂缝 ,裂缝的平均分数维值为 1.44 ,它们构成较好的渗流网络系统 ,使油藏分布呈块状特征。受近东西向现应力场的影响 ,北西向裂缝的渗透率大于北东向裂缝 ,但在开发中该组裂缝开度的闭合速率也快于北东向裂缝。该油藏中大断裂主要是起分割作用 ,目前处于工作状态的主要是中、小断裂系统、宏观裂缝系统及溶蚀后开度较大的部分微裂缝。根据油藏的渗流特征 ,以断块为单元进行注采井网调整 ,可取得较好的开发效果

| Abstract: | The characteristics of fractures and their percolation in Jingbei buried\|hill pool in Damintun depression play important roles in reservoir development. There are NW and NE directional fractures in the pool. The average fractal dimension of the fractures is 1.44. These fractures link up each other and form a good network system. The reservoir shows blocky characteristic. By the effects of modern stress field, the percolation of NW fracture is bigger than that of NE fracture. The declining rate of NW fracture aperture is greater. In the pool, the big faults mainly breaked up the fractures system and the cracks which affect the percolation system are small faults, macrofractures and some solution microfractures. According to the percolation characteristics of fractures and faults, the production pattern may be adjusted by the unit of fault block. |
