1988年大洼油田开始投入开发后,注水后期的开采阶段综合含水已达到87.1%。针对高含水的问题,我厂大洼油田自2011年起实施深部调驱,随着注水油田的开发调驱不断深入,目前受效油井也日渐增多,与此同时,油田的采出度也相应的得到提高而剩油的分布也日渐变得复杂起来、并附带一系列的问题,从整体上看给油田的后期开发增加了一定的难度。在调驱区块选择部分井实施提液技术,有利于剩余油的采出,提高调驱效果。 After the Dawa Oilfield began to be put into development in 1988, the comprehensive water content in the later stage of water flooding reached 87.1%. In response to the issue of high water content, the Dawa Oilfield in our plant has been subject to deep flood control and flooding since 2011. With the development of flooding oilfields, the number of effective oil wells is also increasing at the same time. At the same time, the oil recovery also corresponds And the distribution of remaining oil is also becoming increasingly complicated, with a series of problems, which adds a certain degree of difficulty to the post-development of the oilfield as a whole. In the drive part of the block selection and implementation of liquid extraction technology is conducive to the remaining oil recovery, improve the drive effect.
