The influencing factors of gas-oil ratio in production were studied by numerical simulation method
Research Institute of Exploration and Development of Daqing Oilfield Co. Ltd, Daqing, Heilongjiang, 163712
In recent years, the gas-oil ratio of LaSaxing Oilfield has been on the rise and the variation characteristics of gas-oil ratio of each plant are quite different. The high production of gas leads to the intensification of three-phase interference of oil, gas and water, and the poor fluidity of crude oil after degassing, which affects the overall development effect of the oilfield. Though the method of oil and gas water three phase numerical simulation, the conceptual model was established. Based on the model, analysing the change of producing gas-oil ratio by designing the scheme of numerical simulation under different factors points out the results——the formation pressure is the key factors influenced the producing gas-oil ratio change and the formation pressure level determines the trend of the producing gas-oil ratio. The results provide a technical support for oilfield production safety and the optimization of the ground production system, and achieve an important practical significance for oilfield sustainable development.
