摘要
大芦湖油田属于特低渗透油田 ,1 996年注水开发效果变差。本文根据低渗透裂缝油藏的地质特点和开发状况 ,采用不稳定注水和改向注水方式来改善注水效果 ,通过优选注水方式、注水时机和注水参数 。
Daluhu oil-field is in a low permeability and full of crack. The exploitation effect became worse since 1996. According to its geology character and status of development, this paper adapt the unstable waterflooding and crossflooding to enlarge the sweep efficiency and enhance the ultimate oil recovery by select the water-injection mode, water-injection time and parameter and got a good result.
