Zarzaitine油田剩余油挖潜技术研究

阿尔及利亚Zarzaitine油田F4油藏是海相环境下发育的，具有的气顶和边水的整装不对称背斜油气藏，其砂体厚度较大，分布稳定，但纵向和平面非均质性强，目前已经进入开发后期。为改善油田开发效果，本文采用油藏数值模拟的方法，通过方案优选，确定了该油藏的剩余油挖潜方案：以井网调整为基础，细分层进行注水开发。实践结果证实，所取得的研究成果对海外类似油田开发具有指导意义。

potentials tapping technology of remaining oil of F4 reservoir in Zarzaitine oilfield,Algeria

Algeria Zarzaitine oilfield F4 reservoir is groethed in marine deposit.It is a asymmetric anticline and supersaturation reservoir with gas cap;the sand body has a good thickness and distribute stability.but container horizon has anisotropy.This reservoir is in the high water cut stage.To improve development effectiveness,this article studied 3 kinds of plan to pick the remaining oil by numerical simulation.By contrast,the best plan is :on the basic of adjusting the well patterns,subdivision of the reservoir...
