Research On Working Parameter Adjustment Methods Of Pumping Well And Screw Pump Well

In the process of the production of oilfield water injection, the phenomena of high or lowsubmergence of pumping well and screw pump well before and after the reservoir hydraulicfracturing always occur. But at present, the working parameter adjustments of pumping welland screw pump well primarily are depended on artificial experience, lacking of reliabletheory basis. Therefore, it is significant to research working parameter adjustment methods ofpumping well and screw pump well.Based on the numerical calculation and analysis of the oil well inflow performancebefore and after the reservoir hydraulic fracturing, the pump efficiency of pumping and screwpump after adjusting the working parameters for the submergence, the checking of the suckerrod strength of pumping well and screw pump well, the working parameter adjustmentmethods of pumping well and screw pump well are given;.using Visual Basic6.0programming language, the “Working Parameter Adjustments on Pumping Well and ScrewPump Well” programme was programmed; and applying the programme metioned above,the working parameters.of10pumping wells and screw wells before and after the reservoirfracturing such as T-1in Daqing oilfield were adjusted.
