精细油藏描述技术在联西区开发调整中的应用

Application on the developmental adjustment for fine scale reservoir description of the west block of Lianmengzhuang Oilfield

针对联西区开发过程中出现的矛盾及问题,重点开展了目的层细分对比、构造、沉积微相、油层分布特征为主要内容的精细油藏描述研究工作。通过精细油藏描述,解决了原注水开发过程中动静态矛盾,认清了剩余油分布规律,确立了下步主要开发调整思路与对策。应用精细油藏描述成果指导恢复注水试验,取得了阶段性成效,为下步重建井网、二次开发创造了有利条件。

On the base of the developmental contradiction and problems of the west block of Lianmengzhuang Oilfield,a study on fine scale reservoir description is carried out,including stratigraphic division,geological structure,sedimentary microfacies and hydrocarbon distribution.Through fine scale reservoir description,the static and dynamic contradiction has been solved during the primary water flooding developmen,the law of remaining oil distribution has been recognized,and the next main pathway and countermeasure of developmental adjustment have been established.Utilizing the achievements on fine scale reservoir description instuct the resuming waterflooding trial,initial success has been won,which will create favourable conditions for the next reconstruction of pattern of wells and secondary development.
