利用报废井侧钻模式挖潜增效

Sidetracking of Abandoned Well to Reduce Costs

断块油气田进入到开发后期,井损率逐渐上升,而井损区的剩余油挖潜成为提高采收率的重要途径。利用报废井进行侧钻不但可大幅度减少钻井费用,还可避免进行二次征地减少青苗费用支出。从根源上降低了各项费用,是一种被广泛推广的节能创效模式。文章试从利用报废井侧钻在WZ油田的应用对该模式进行了探讨与研究。

Well-loss rate will gradually increase in late stage of development, while potential tapping of residual oil in well damage zones is an important way to enhance oil recovery. Sidetracking of abandoned wells not only can greatly reduce drilling cost, but also avoid secondary land acquisition, which cuts costs at the source and is a widely promoted model for energy saving and beneift making. This article studies the model of sidetracking of abandoned wells in Wenzhong oilifeld.
