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。
斷塊油氣田進入到開髮後期,井損率逐漸上升,而井損區的剩餘油挖潛成為提高採收率的重要途徑。利用報廢井進行側鑽不但可大幅度減少鑽井費用,還可避免進行二次徵地減少青苗費用支齣。從根源上降低瞭各項費用,是一種被廣汎推廣的節能創效模式。文章試從利用報廢井側鑽在WZ油田的應用對該模式進行瞭探討與研究。

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.
