一些低渗透油田在投入开发一段时间后产量递减快,为了稳产,采用注水开发的方式来补充地层能量,但注水后部分井水淹、水串严重,而大部分油井注水不受效或受效不明显,为了解决这个问题,必须深入储层内部,认识造成这一问题的深层次原因。了解注水过程中基质渗流与井间水淹机理,为开发后期提供重要的资料。

Some low-permeability fields decelerated rapidly after they were put into development for a period of time. In order to maintain stable production, water injection was used to supplement formation energy. However, some water flooded after flooding caused serious water strikes and most of the wells were not affected or affected by water injection Obviously, in order to solve this problem, we must go deep into the reservoir to understand the underlying causes of this problem. Understand the matrix seepage and waterflooding mechanism during waterflooding, and provide important information for later development.
