摘要
采用Eclipse软件,用数值模拟的方法,对青海乌南油田乌五断块N21油藏,在基质渗透率各向同性条件下,研究对比了五点面积井网、菱形反九点井网及正方形反九点井网等3种注采井网在不同井距、不同井排比条件下的压裂裂缝穿透率对开发效果的影响。经对比,推荐乌南油田乌五断块N21油藏采用井排比为2、井距350～400m的五点面积井网。
By using Eclipse software and numerical simulation method,The N12 reservoir of Wuwu fault block in Wunan oilfield is simulated.Under isotropic condition of the matrix permeability,three well patterns such as five-spot areal well pattern,inverted nine-spot rhombic and square well pattern are compared for getting the effects of the fracturing fracture＇s penetration rates on production performances.At the result,five-spot areal well pattern is recommended for this block,and the ratio of well spacing to well row distance of 2 and well spacing of 350~400 m will be most suitable.
