Study And Application On Techniques For Improving Pump Full Coefficients

The Average pump efficiency of sucker rod in Jiangsu oilfield is51%,280wells isbelow30%, about20.4%of the total number of wells. Discovered through analysis ofpump full of coefficients is a major factor affecting the pump efficiency, and workingparameters of gas and unreasonable is main factor affecting the pump filled with acoefficient of. Gas oil ratio in part for oil field block, while low-sunk well due tounreasonable working parameters, these two factors result in pump full of coefficient is low,development and optimization of working parameters of new gas anchor method of study.New gas anchor research area, through on General gas anchor application effect andadaptability analysis, used numerical simulation optimization method on new gas anchor ofstructure parameter for optimization, while combined indoor experimental evaluation,development has new gas anchor, the gas anchor used double spiral variable pitch structure,while screw Rod top opened exhaust hole, internal hollow, and side wall cloth radial passhole of double exhaust channel structure, effective to improve wells of points gas efficiency;work parameter optimization method area, for currently common pump full coefficientcalculation method only consider gas effect, For fluid low or high viscosity crude oil wells,get pump full of coefficient deviates from the actual value of a largerphenomenon.Considering factors such as the nature of the crude oil, pump swabbingparameter with coefficients in the pump effects research fixed pump full of coefficientcalculation method and parameter optimization of the use of VB language developmentwork on the basis of software, achieve maximum pump efficiency parameter optimizationdesign for the purpose.2010new field application of gas separator in well27since,averaging of single well pump efficiency8.2%; use parameters optimized applicationsoftware optimization of working parameters on site8wells, the single averaging12%pump efficiency. By field application that new gas separator application better, developmentof optimization software advanced scientific results reasonably reliable.
