Study Of Predicting And Simulation Of Water Flooding Production In Oil Field

Production system in oil field is a large-scale and complicated engineering system, Bigger is system complicated level of the system structure is bigger. The production process in oil field is a dynamic cource, Along with the development of oil field, How to adjust production system structure and suit the change of production state is a work assignment frequently for oil field planning design and production management person. Combine with the development history of oil field production, study the change course of dynamic system of oil field, reveal the regularity of system, and predict the state change of oil field development with these laws, thus make adjustment planning of the production system,ensure stable run of production system under high efficiency and low cost. Research object of the dissertation is water flooding system in oil field, build the suitable predicting model, aim at predicting water flooding yield, according to the fixed computer simulation method, calculates out operating situation of system under the coming operating mode.The dissertation regard the Poisson formula that is descripted by professor Weng Wenbo as the basic structure of predicting model, according to the real history production data of oil field, adopts the least square method to carry on the parameter estimation, built predicting model of oil yield and the synthetical moisture content, thus counts out predicting water flooding yield.Based on water flooding yield on predicting year, according to structure of real producing system, fix the forecasting simulation operating mode. Predict the running state of system; on the other hand can predict the running state of system under simulation operating mode according to imagined water flooding yield-, state of well and station, then analysis welk station and system.Predicting result provided the most advantageous water pressure and the optimum well number under predicting circumstance of water flooding system.The dissertation programs the software of forcasting and simulation in production process of water flooding system in oil field, the software is used to water flooding system in Putaohua oil field and put forward the corresponding analytical result and suggestion, the result shows that this software can be used to predicts the coming operating circumstances of production system in oil field.
