摘要
双重介质油藏不同部位裂缝发育程度差异很大,非均质性强,储层物性平面差异很大。采用常规直井注水开发,油井见水后含水率上升快等问题,开采速度和采收率会比较低。裂缝发育的双重介质油藏对注水开发井网的部署极为敏感,采油井和注水井应如何组合才能获得更为有利的渗流场,从而取得更好的注水开发效果十分关键。
The development of fracture in different parts of double medium reservoir is very different, the heterogeneity is strong, the difference of reservoir physical property plane is very large.Using conventional straight well water injection development, the oil well see water content after water content rising fast, the mining speed and recovery rate will be relatively low. The double medium reservoir of fracture development is very sensitive to the deployment of water injection development well network.How to combine oil production well and water injection well to obtain more favorable seepage field, so as to obtain better water injection development effect is very important.
