Stack Effect In The Experimental Study Of The Injection-production Well

With the development of oilfields,the water content of the oil wells is increasing,resulting in the increase of sewage treatment costs and facilities construction.The same well injection and production technology can improve the situation.This technology is installed in the summer oil and water separator to achieve oil and water Separation.In the same layer of the same layer of injection and production process,the output layer of oil-oil mixture of more oil and water into the separator separation,the future to further improve the same well injection and production effect,in the packer to install chimney tube to reduce separation The oil content at the device,to improve the separator separation effectIn this paper,the characteristics of oil and water separation in the underground are studied by referring to the literatures of oil and water separation at home and abroad by means of theoretical analysis and indoor simulation experiment.In this paper,the effect of the chimney effect on the injection and production in the same well is studied by using the chimney principle and the method of installing the long tube(chimney tube)on the upper and lower channels of the packer.Based on the actual situation of the research,this paper establishes the experimental scheme of this subject,uses Fluent software and its corresponding pre-processing software Gambit to simulate the flow of oil-water two-phase flow in the separation equipment and design and design in the special laboratory of Daqing Petroleum Institute The experimental results show that the chimney effect of different chimney and the chimney can be used to study the influence of chimney effect on the effect of chimney effect on the separation of oil and water in the downhole.Through the indoor experiment method,The effect of moisture content.
