SAND CONTROLLING TECHNIQUE AND ITS APPLICATION FOR THE POLYMER-FLOODING OIL WELL PUMP
摘要
Abstract
After the polymer flooded block entering the peak stage of the production,the concentration of the produced polymer liquid increases continuously,the rate of servicing the polymer flooding pumps is very high,the sand sticking problem has become the main factor affecting the servicing pump rate of the polymer flooding.In the light of the technical problems in the application process of the large-channel oil well pump,the managing idea of " Preventing first,Combining the prevention and elimination" was put forward,the sand preventing pipe and equaldiameter sand discharging pump were developed.The sand discharging pores were evenly distributed on the plunger of the oil well pump,the material qualities of the piston and the valve ball to improve the wear resistance and enhance the ability of the sand elimination,thus the sand within the pump cylinder and around the piston can be discharged into the pump piston and then flowed out with the oil flow;the single-flow valve was developed on the pump to prevent the sand deposition from sticking the pump in the produced liquid after the shutdown of the oil pumping unit.Much better field-applied effects have been achieved for the sand controlling technique in the polymer-flooded oil pumping well,so the pump serving cycle of the polymer-flooded sand-stuck wells can be obviously prolonged and furthermore can meet the requirements of the sand control in different sand production stages.关键词
