In view of the complexity of reservoir development,the reservoir numerical simulation method is used to achieve the optimal design for effective exploitation and maximum economic benefits of the reservoir in the paper.After the objectives of reservoir simulation are formulated and the necessary basic data are prepared,the corresponding numerical model is established according to the simulation area need.Then the historical fitting of daily oil production,water content and cumulative oil production are carried out to make the simulation results consistent with the actual oil field data,so as to accurately reflect the reservoir characteristics.Based on the distribution of remaining oil obtained,different prediction schemes are compared to select the pattern of well improvement scheme with better development effect,which is used to improve the degree of reservoir exploitation in the subsequent production and development process.Reservoir numerical simulation has become a reliable technical means in the exploitation of oil and gas fields.Based on the current understanding,the future development trend of reservoir numerical simulation methods are prospected.
