摘　　要：对于注水开发的油田,随着注入水的不断增加,平面矛盾和层间矛盾逐渐显现出来。近年来研究发现,油层内部发育了不同成因的单砂体,单砂体的连通程度,对改善注水开发效果至关重要。针对D区块开发现状,对储层单砂体进行了划分,为下一步分层注水奠定了基础。For oil fields developed by water injection,with the continuous increase of injected water,plane contradiction and interlayer contradiction gradually appear.In recent years,it has been found that single sand bodies of different genesis are developed in the reservoir.The connectivity of single sand bodies is very important to improve the effect of water injection development.According to the development status of block D,the single sand body of reservoir is divided,which lays a foundation for layered water injection in the next step.
