针对开发后期油井出水,采取相应的堵水技术来增加油井产量。讨论了吉林油田不同井况油井堵水技术概况,并做了简要分析。随着吉林油田已开发生产年限的进一步增加,越来越多的油井已进入或将进入产量递减阶段,由于大部分油井采用注水开发,再加上有些油田天然边、底水的影响,在开发后期就会产生油井出水,严重时可形成油井水淹。油井产水后降低了产油量,甚至损失储量。目前,吉林油田大部分油井中已处于中、高含水期,产水已成了影响原油生产的主要问题。因此,有必要开展油井堵水研究,解决水驱油田后期开发的高含水问题,提高油井产量,最终提高老油田的采收率。
For the late development of oil well water, take the appropriate water plugging technology to increase oil production. The general situation of oil well water shutoff technology in Jilin Oilfield at different conditions is discussed and analyzed briefly. With the further development of the productive life of Jilin Oilfield, more and more oil wells have entered or will enter the phase of declining production. Since most oil wells are developed with waterflooding and the natural edge and bottom water of some oilfields, Oil wells will have a late water, oil wells can form a serious flooding. Oil wells reduce oil production and even lost reserves. At present, most of the oil wells in Jilin Oilfield have been in the middle and high water cut-off periods. Water production has become a major issue affecting the production of crude oil. Therefore, it is necessary to carry out oil well water shutoff research to solve the high water cut problem developed in the late stage of waterflooding oilfield, improve the oil well production and finally improve the oil recovery in the old oilfield.
