摘要
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。
Aiming at excess water production in the later stage of oilfield development,corresponding water plugging technology is often used to increase the production of oil wells.In this paper,application status of the water plugging technology in different wells of Jilin oilfield was discussed and analyzed.With the further increase of Jilin oilfield development and production years,more and more wells have entered or will enter the stage of production decline.Because most wells adopt water flooding development technology,and are affected by natural boundary and bottom water,produced water in oil well will appear in the later stage of development,which can form water flooded well if the water production is serious.Well water production reduces oil production,and even loses reserves.At present,Jilin oilfield is in the period of high water cut,the water production has become a major problem affecting crude oil production of most oil wells.Therefore,it is necessary to carry out research on the water plugging technology for high water cut oil wells to solve the problem of high water cut in order to increase oil production and improve the recovery of old oil field.
