摘　　要：渤海油田因FPSO处理液量能力受限,高液量生产井(尤其是水平井)会因生产需求被迫关停,同时水平井在开发中后期,底水锥近严重导致开发效果变差。为改善开发效果,渤海QHD32-6油田首次利用了中心管采油技术,实现了水平井选择性堵水,将长期限液停产井成功复产。A25h井实际应用中心管采油技术后,日产液量下降351 m3/d,含水下降5.9%,增油24 m3/d,该技术为渤海油田水平井增油控水工作提供了技术方向。Bohai oilfield has limited FPSO capacity,and wells of high mass production,especially horizontal wells,are likely forced to shut down.In addition,bottom water coning severely affects horizontal well performance in the late life of oilfield development.Therefore,base pipe technology was used for the first time in Bohai QHD32-6 oilfield,had realized selective water shut off in horizon wells and resumed production from wells of long-term production restriction and shutdown.After applying the base pipe technology,Well A25h had mass production reduced by 351 m 3 / d,water cut reduced by 5.9% and oil production increased by 24 m 3 / d.This technology is significant for increasing oil production and water control in the horizontal wells of Bohai oilfield.
