Reservoir numerical simulation technology is an important means of reservoir analysis， and it is a powerful tool for oilfield developers to design development schemes， proceed with dynamic tracking adjustment， and enhance oil recovery of reservoirs.In order to clarify the future development directions of reservoir numerical simulation technology in Shengli Oilfield，this paper reviewed the development process of reservoir numerical simulation application technology and independent intellectual property software in Shengli Oilfield over the past 60 years and summarized the innovative progress in numerical simulation application technology in many fields since the“ 13th Five-Year Plan in 2011-2015” period， which is applicable to current development and geological characteristics of Shengli Oilfield. The fields covered fine reservoir description in ultra-high water-cut stage， pressure flooding development in low-permeability reservoirs，heterogeneous combination flooding，multiple thermal combination flooding in heavy oil reservoirs， high-pressure CO2 miscible flooding， and integrated development of shale oil by large-scale fracturing. Then，this paper introduced the development and application of several reservoir numerical simulation software with Shengli characteristics，involving water flooding， chemical flooding， and micro and intelligent simulation. Finally， it was pointed out that under the current development situation of Shengli Oilfield， the reservoir numerical simulation is facing great challenges in terms of refinement，scale，efficiency，and collaboration approach， and the numerical simulation of reservoirs should be further developed towards integration，parallelization， and intelligence， so as to provide technical support for improving the quality and efficiency of Shengli Oilfield development.
