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$N^{1}_{2}$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$N^{1}_{2}$油藏采用井排比为2、井距350~400 m 的五点面积井网。

Abstract: By using Eclipse software and numerical simulation method, The $N^{1}_{2}$ 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.

Key words: Qaidam basin, Wunan oilfield, Wuwu fault block, low-permeability reservoir, fracturing development, injection-production well pattern, numerical simulation
