The Reservoir Engineering And Numerical Simulation Study Of BXX Well Area XXX Group

This research evaluated all sorts of the production in the existing development system and found out the problems existing in production through reservoir engineering method, combining with black oil model of historical fitting numerical simulation results. This study found out the distribution of remaining oil by numerical simulation, and combined with the research results of reservoir engineering part. designed production plans, seleced the best production plan through comparing and made predictions. The main research contents are as follows:1. Calibrated Water drive process and recoverable reserves Under current production plan by using all sorts of empirical formulas and water drive curves;2. Evaluated the dynamic characteristics of waterflooding from moisture content,oil production and the pressure distribution characteristics;3. Discussed the bai 48 fault closeness and edge water problems by combining basic geological research and dynamic production material;4. Evaluated Waterflooding effect from water penetration quantity, carry water rate and water flooding index, water flooding control degree four aspects;5. Evaluated injection-production corresponding condition of the small layers through liquid producing water quantity, Analysed the flowing directionin of injecting water by non-parameter statistics method and numerical simulation method;6. Established reasonable injection and suitable injection-production ratio models in each development phase based on the Logistic spinning back of WengWenBo model;7. Established reservoir numerical simulation of black oil model, studied the distribution characteristics and the control factors of remaining oil by using the results of numerical simulation historical;8. Adjusted the production plan According to the distribution of remaining oil and reservoir engineering research, designed many sets of production plans and optimized and predicted.
