The Research On Reasonable Sinking Pressure Of Oil-Well Pump For Xingbei Oilfield Developmentzone

The determination of reasonable sinking pressure of oil-well pump is the core element of well management for the pumping unit. It is the key factor that can ensure the pumping unit working under the stable and efficient operation. It can also well advanced standing for longer periods and ultimately achieved to create the best economic benefits.On the basis of investigating the related literature domestic and overseas in this paper.Comprehensiving analysis various factors including gas,viscosity, moisture content, gas pump diameter,the capacity of liquid producing and other factors, described the working principle,system efficiency of pump and pump efficiency calculation method in detail. Then set the design of trainiing thought and method for the determination of reasonable sinking pressure.According to the production situation of different oil Wells, determining that predicting productivity is the foundation of the oil-well production system.Adopting the method of weight distribution,Selecting for and mining coordination, pump efficiency, economic efficiency,system efficiency, rate of equipment utilization five target parameter for optimization design the combination of sucker rod. At the same time according to the characteristics of different reservoirs and using the data of field, adopting the method that the highest yield as the optimization target for determining the reasonable sinking pressure of oil-well pump. Finally choosing one typical blocks of Xingbei Oilfield developmentzone for the optimal design,each block has obtained reasonable sinking pressure and pump depth under the rea range of values.Using the Java software for the compilation of the reasonable sinking pressure optimization design, the software can meet the needs of the production of the block oilfields and it can improve the production conditions of oil Wells and obtain the fine using effect.
