摘　　要：王场油田中区潜4^(3)经过近五十年的开发,目前已进入开发中后期。由于储层非均质性严重,平面、层间开发特征差异大且水驱多向受效,长期的高效开发后累产累注量大,地下水驱流线分布复杂,限制后期开发调整。通过开展储层精细描述和构造主曲率分析下的裂缝分布规律研究,形成了一种以定量刻画油水关联性的流场描述及时变规律研究方法,对油藏高含水后期开发调整起到重要的指导作用。The central Qian43 in the Wangchang oilfield has proceeded to the middle and late stage of production after nearly 50 years of development.Such factors pose a limit to the late production adjustment as severe reservoir heterogeneity,significant difference in planar and interlayer development characteristics,multi-directional water flooding effect,the significant cumulative production and injection volume after long-term high-efficiency development,and the complex distribution of water flooding flowline.Based on the study of fracture distribution through the refined reservoir description and analysis of structural principal curvature,a methodology was established for quantitatively determining the flow field description of oil and water correlation and time-dependent variation,which plays an important role in directing the development and adjustment of the reservoirs in the late stage with high water cut.
