[Abstract]:The productivity prediction of the polymer flooding submersible pump well is difficult, and with the increase of the polymer concentration, the operation life of the electric pump is reduced, the pump cycle is shortened and the energy consumption of the unit is increased. Therefore, the optimization design of the selection well selection of the polymer flooding submersible pump well is used to accurately predict the production capacity of the polymer flooding submersible pump well, and to increase the efficiency of the unit and increase the polymer flooding. The adaptability of the submersible electric pump is of great significance. In this paper, a mathematical model of the flow inflow of a polymer flooding oil well is established based on the system efficiency of the submersible pump unit, and the productivity of the oil well is predicted. The numerical model of the fluid temperature distribution and pressure gradient of the polymer flooding wellbore is established, and the pressure gradient of the wellbore fluid is carried out. On the basis of the application of the new type of blade guide, double protector and high power and high grade motor, the mathematical model of the optimization design for the selection of the well selection pump for the polymer flooding submersible pump well is established with the consideration of the constraint conditions, and the Visual Basic 6 program language has been used to prepare the "polymer flooding submersible oil". The program of optimum design for selecting well selection pump for well selection well is applied to the selection of well selection pump for 10 polymer flooding submersible pump wells in a oil production plant in Daqing oil field. The optimization of the well, the submersible pump, the oil gas separator and the double protector, and the optimization of the parameters of the submersible pump well have been realized. The results show that 10 polymer flooding potential is used. In the oil and electric pump well, 9 of them operate efficiently, and the degree of efficient operation reaches 90%.
