The S3 block is located in the middle of the S oil field in the east of Changyuan, Daqing. It has experienced elastic mining, water injection development, encryption adjustment, driving test, subsequent water drive and other development stage. At present, it has entered a high-water period. Based on the dynamic analysis and evaluation of block development and development effects, conduct fine geological modeling and numerical simulation research, and conduct remaining oil-volume evaluation. At the same time, through the calculation of indoor experiments combined with the oil collection project, the research limit of the application technology application is performed. It is clear that the application boundary limit of the S oil field regulating technology is: the lower limit of the penetration rate is 30 md, the lower limit of the valid thickness is 3 m, the well distance is 200 m, the well network is five o'clock at five o'clock Well.com. Through the numerical simulation method, the pilot area injection parameters are optimized, designing the drive solution, and a total of 4 sets of injection schemes. The comparison effect and efficiency. The preferred result of the final injection scheme is: the concentration of the concentration of the main segment of the drive system is 800 mg/L, the injection speed is 0.05 pv/a, the injecting volume of the solution of the drive system is 0.5 PV, and the injection method is injected by the composite segmentation method. Through the adjustment of the combination of the well network, the purpose of achieving the second development of the block, the improvement of the development effect of the block, and the improvement of the final harvesting of the block.
