文留油田断层组合类型对剩余油的控制

Remaining Oil Controlling by the Type of Fault Assemblage in Wenliu Oilfield

文留油田断块油藏内部断层组合可分为单体型、平行型、树枝型和网格型 4种类型 ,对不同的断层组合在注水开发中对注入水阻挡作用以及所形成的剩余油特征进行了描述 ,提出了开采不同类型剩余油的方法 。

The fault assemblage within the fault block reservoir is divided into four types including unit,parallel,branching and grid assemblages,the charateristics of injected water blocking and remaining oil created by the blocking are denoted during the water injection,metheds are proposed for the development of different remaining oil,which provides expeirence for potential production of post development stage in the reservoir
