摘要
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。
The production of some low permeability oilfields rapidly declines after a period of development, in order to realize stable production, the way of water injection development is adopted to complement the formation energy, but some wells arise serious watered out and water channeling problems after water injection, and the water injection of the most wells do not gain obvious effect. To solve this problem, reasons to cause problem must be analyzed from the aspect of reservoir. In this paper, percolation mechanism of matrix and watered-out mechanism between wells during water injection were studied, which can provide important information for later development.
