摘要:
大庆油田目前已进入特高含水期。随着区块采出程度的日益提高,剩余油高度分散,水淹普遍,层间矛盾较为突出,水驱效果变差。目前,常规的化学调剖方法还很不完善,不能够对高渗层或大孔道深部进行封堵。以北三区西部SⅡ1+2b层为例,对深部液流转向技术进行研究,并且提出封堵水窜通道,增加中低渗透层利用率,改善水驱效果的新技术,为高含水油田进一步改善水驱开发效果提供新的途径。
Abstract:
At present,Daqing Oilfield has entered the extra high water-cut stage.With the increasing recovery percent of reserve,the effect of waterflooding becomes worse and worse because of high scattered remaining oil distribution,more watered-out wells,and serious interlay interference.Now,the conventional chemical conformance control technologies can not be used to plug deep parts in high permeability layer or large channel.Taking SⅡ1+2b formation in the western of Bei 3 block as an example,we studied the deep fluid diversion technology.A new technology for improving effect of wateflooding was proposed,which includes plugging water breakthrough channel and increasing the utilization of medium to low permeability formations.The technology can provide a new way for further improving the development effect of water flooding oilfield at high water-cut stage.
