文卫马油田经过近20年的开发,井况恶化日益严重,随着套损井的增多和大修侧钻力度的加大,4″套管井逐步增多,为了实现调整层间矛盾,部分井需要分注注水,但受套管内径的影响,配套的4″套管分注技术还不完善,造成部分井不能达到应有的分注效果。2010年推广应用RF免投捞分注管柱,减少了因无法正常调配造成的作业换封,延长了分注井换封周期,提高了测试成功率和措施效果,对于油田开发后期的油田注水开发,提高油田采收率具有重大意义。
After nearly 20 years of development, Wen Weimar oilfield has worsened the well conditions. With the increase of casing damage and the increase of overhaul and sidetrack drilling, 4 “cased wells have gradually increased. In order to adjust the interlayer conflicts, some wells need However, due to the influence of the inner diameter of the bushing, the matching 4 ”cannula dispensing technique is still not perfect, resulting in that some wells can not achieve the proper dispensing effect. In 2010, the application of RF free fishing dispensing column reduced the replacement of jobs due to the inability to properly deploy, prolonged the replacement cycle of the injection wells and increased the test success rate and the effect of measures. For the oilfield waterflooding in the late stage of oilfield development Development, improve oil recovery is of great significance.
