低渗透油藏超前注水理论及其实际应用

Theory and Practical Application of Advanced Water Injection for Low Permeability Reservoirs

低渗透油田在开发时容易出现裂缝性油藏,注水也很容易受到裂缝影响而不均匀,导致油田产量低、稳产难、采收率低,低渗透油藏超前注水技术很好的解决了这个现状。本文先介绍了低渗透油藏超前注水理论的机理,重点以甘谷驿采油厂顾屯区块为例,说明低渗透油藏超前注水技术的应用。

With continuous development of science and development of low permeability oilfield, water injection is technology in China, fractured reservoirs are easy to appear in the easy affected by the fracture, which can result in low yield, advanced water injection for the low permeability reservoir is a good solution to this situation. In this paper, the mechanism of advance water injection theory for low permeability reservoirs was introduced. Taking Gutun block of Ganguyi oil production plant as an example, annlication of advanced water injection technolozv in low permeability reservoirs was discussed.
