针对桥式偏心、同心双管等分注新技术在大港油田高温、高压深斜井试验中存在的投捞测配遏阻遇卡、调配精度低、费用高、可靠性差等技术难题,开展了桥式同心分注技术研究与应用.现场应用29口井,施工成功率达到90％以上,分层水量测试调配精度达到96％,表明桥式同心分注技术在解决高温、高压深斜井井下分注技术难题方面具有显著的技术优势.%The application of bridge type eccentric separate injection technology and concentric dual-barrel separated injection technology were developed in the deep inclined wells of high temperature and pressure in Dagang Oilfield where many problems exist,such as the huge difficuIties of pulling and running for water injection allocation,the low accuracy in the allocating,the high cost and poor reliability.In order to solve these problems,the bridge concentric separated injection technology is developed and applied,which implements 29 wells in deep inclined wells,and the success rate of treatment has reached to 90％ with 96％ allocating accuracy.The results of test show that the technical problems of underground separated injection will be a great advantage in deep inclined wells of high temperature and pressure.
