[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 nu⁃merical 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 three-dimensional geological model on the basis of fine stratigraphic comparative research, use numerical simula⁃tion 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 devel⁃opment. [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 hasreached 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 beaware 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 pro⁃motion value for tapping the remaining oil potential of other similar reservoirs.Keywords: well seismic joint; integration of modeling and numerical simulation; complex fault block res⁃ervoir; remaining oil distribution0 引言近年来，复杂断块油气藏成为增储上产的主阵地之一，复杂断块油藏建模数模一体化技术研究，是建立精准油藏模型的基础，对特高含水期自然断块周边滚动增储、老区断块群剩余油潜力认识与开发调整意义重大［1-2］。
