The Development Of Injection Well Integrated Parameter Tester And Improvement

For multiple simultaneous development of oilfield,take early internal water injection to keep pressure oil production,oil field is an important technology of the high and stable yield for a long time.In the different stages of oilfield development using suitable for oil field geological conditions of water injection technology is the key to the enough water injection,water injection.With the deepening of oilfield development,three yuan,although carried out polymer flooding of daqing oilfield drilling and other advanced technology,but the water drive oil production is still dominant,daqing oilfield has entered the determining,the development difficulty is bigger and bigger,more and more high to the requirement of water injection process.In recent years,with the development of the oilfield,the separate injection well number increases year by year,the water injection well test process faces more challenges.Multilayer waterflooding oil field at the same time,the main problem is hysteresis and interlayer interference problems of formation water injection,which is lead to inaccurate layered testing and deployment of the main causes of inaccurate layered injection.We are a large number of indoor test and field test and on the basis of mathematical modeling,injection Wells is developed circuit parameter tester,and the corresponding supporting software development,the appearance of the instrument and the flow channel structure is similar to ordinary eccentric plug.Ordinary ceramic water nozzle in the eccentric water distributor,after implementation of water injection interval tubing pressure,formation pressure and flow rate,temperature of dynamic monitoring.Then,according to the process change in the ground water injection pressure for continuous monitoring,can accurately comprehensively reflects the formation stability real suction conditions.At the same time,the correction coefficient of water mouth wear study,in order to master the different sizes of water nozzle under different time,the wear under different traffic situation,find out the relationship between the wear degree and time,flow,and eventually make comprehensive parameter tester for supporting software with water injection nozzle wear correction function,reduce equipment from working long hours because the water nozzle wear of the test error.The function of the instrument to carry on the further perfection and improvement.The success of this technology,and realized injection well water injection condition monitoring for a long time,improve the comprehensive traffic allocation algorithm,realize the energy saving water injection mix.To improve traditional injection injection allocation and test mode,scientific and reasonable water injection for oilfield water injection,saving energy and reducing consumption,improve the efficiency of water injection rate and injection plays a very important role.virtual training simulation is training simulation based on virtual reality technique,which is the computer mapping to the taining process.As the virtual technique became more and more mature,virtual human will be embedded in the environment of virtual training simulation,as the expresstion the trainee in the environment of virtual training.Trainee can interact with virtual human in the virtual environment,immersing in it,studying and training.The expressing method of human body model are analyzed and studied in this paper,and selected...
