日前,胜利油田采油研究院浅海所科研人员正在海洋采油厂CB1D-4井上加紧分层注水测调一体化施工。施工完成后,该井可从常规注水转为精细注水,能有效控制含水和自然递减率。CB1D-4井分层注水是该技术在海上应用的第99口井。技术施工成功率100%,调配精度从78%提高到92%。目前,胜利海上油田地层压力稳中有升,含
Recently, Shengli Oilfield Oil Research Institute of shallow sea researchers are drilling CB1D-4 offshore oil production wells to step up stratified water injection leveling integrated construction. After the completion of construction, the well can be changed from conventional water injection to fine water injection, which can effectively control the water content and the natural decline rate. CB1D-4 well stratified water injection is the 99th application of the technology at sea. Technology construction success rate of 100%, deployment accuracy increased from 78% to 92%. At present, Shengli offshore oilfield formation pressure steadily, with
