【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。更多还原

【Abstract】 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.更多还原
