河南油田江河油矿和双河油矿的掺水管网运行数年后腐蚀穿孔频繁,维护成本高,严重影响正常生产。研究采用高温产出液就地脱水回掺技术,替代原掺水管网,即利用部分油井的高温产出液就地脱水回掺。实施后,单井掺水温度与压力都大幅度提高,同时减少了联合站的重复处理量,投资少、效益大,对老油田的改造有极大的借鉴意义。 Corrosion and perforation frequently occur after several years of operation of the mixed pipe network of Jianghe Oilfield and Shuanghe Oilfield in Henan Oilfield, causing high maintenance costs and seriously affecting normal production. In the study, the dehydration back-mixing technology was used to replace the original water-sprinkling pipe network by using the high-temperature production solution in place, that is, the high-temperature production solution of some oil wells was dehydrated and dipped in situ. After implementation, single well water temperature and pressure are greatly increased, while reducing the joint station of the repeated handling capacity, less investment, great benefits, the transformation of the old oilfield has great reference.
