摘　　要：基于八面河油田面14区沙三上5砂组地质特征、开发规律的研究,提出了提水、提液的“双提”开发技术。通过数值模拟,结合老井历史提液生产情况,确定了该类油藏合理提液界限及注采比;通过动态监测、油藏工程、数值模拟对该区域的剩余油进行了刻画。对不同压力保持水平、不同采出程度区域进行了差异化提液,实施后采油速度由0.27%上升到0.42%,开发效果明显好转,为特高含水油藏经济有效开发提供了依据。Based on the study of geological characteristics and development pattern of Sha-3 upper 5 member of sand sequence in the Mian 14 area of the Bamianhe oilfield,the"double-extraction"development technique for water and liquid extraction was put forward Through numerical simulation and combined with the fluid-extraction production history of old wells,the rational extraction limit and injection-production ratio of this type of reservoirs are determined.The remaining oil in this area is characterized by dynamic monitoring,reservoir engineering and numerical simulation.Differential extraction was carried out in areas with different pressure maintenance levels and different recovery degrees.After the implementation,the oil recovery rate increased from 0.27% to 0.42%,and the development effectiveness improved significantly,providing a basis for the economic and effective development of ultra-high water cut reservoirs.
