摘　　要：【目的】为解决复杂断块油藏面临的油藏构造碎小、低序级断层数量多、准确识别难度大和油藏描述效率低等问题。【方法】充分应用地震资料、测井数据等储层信息,开展井震联合建模数模一体化技术研究,利用三维地震资料,结合现场生产动态响应情况开展断层精细解释、断裂系统精细刻画,准确落实低序级断层发育及组合方式,在精细地层对比研究的基础上,建立三维地质模型,利用数值模拟与模型互检,迭代修正更新模型,尽可能保证模型精准,以便厘清剩余油分布规律,指导后期开发。【结果】该技术在胜利油田复杂断块区D块、L块等多个区块先后进行了应用,结果显示,断点吻合率均达到100%,数模含水拟合率达到90%以上。【结论】该技术能够实现复杂断块构造的精细描述,对特高含水期自然断块剩余油潜力认识、提高老区采收率具有重要意义,对其他同类型油藏的剩余油挖潜具有指导意义和良好的推广价值。[Purposes]This paper aims to solve the problems faced by complex fault-block reservoirs,such as small reservoir structural fragmentation,large number of low-sequence faults,difficulty in accurate identification and low reservoir description efficiency.[Methods]This paper will fully apply seismic data,logging data and other reservoir information,carry out research on the integrated technology of geological modeling and numerical simulation Based on Well-log and Seismic Data,use three-dimensional seismic data,combined with on-site production dynamic response to carry out fine fault interpretation and detailed characterization of fault system,accurately implement the development and combination of low-order faults,establish a threedimensional geological model on the basis of fine stratigraphic comparative research,use numerical simulation and model mutual inspection,iteratively correct and update the model,and ensure the accuracy of the model as much as possible,so as to clarify the distribution law of the remaining oil and guide the later development.[Findings]This technology has been applied in multiple blocks such as D blocks and L blocks in the complex section area of Shengli Oilfield.The application results show that the breakpoint kinetic rate has reached 100%,and the digital mode water convergence rate has reached more than 90%.[Conclusions]This technology can realize the fine description of complex block structure,which is of great significance to be aware of the remaining oil potential of natural breaks during the high-moisture period,and to improve the EOR of the Old Area Oilfield.And in addition,the technology has guiding significance and good promotion value for tapping the remaining oil potential of other similar reservoirs.
