РАДИАЛЬНЫЙ КОМПЕНСАТОР ДЛЯ СНИЖЕНИЯ УРОВНЯ АВАРИЙНОСТИ НА НЕФТЕДОБЫВАЮЩИХ СКВАЖИНАХ

Abstract

The main cause of accidents with submersible installations of electric centrifugal pumps is an increased level of vibration of the installation. An important way to protect against increased vibration level is vibration isolation. The authors propose a radial compensator to reduce the formation of limit values of stress concentrations in the tubing string, to prevent them from breaking to the bottom of the well, twisting the electrical cable of the submersible pumping unit. In order to evaluate the efficiency of using a radial compensator, tests were performed on a vertical automated VIG-98 test bench. The vibration level was measured using the mean square vibration velocity in mm/s using the Diamex vibration analyzer. Conducted a test of the selected pump in the well without the use of a radial compensator. The magnitude of the vibration was 1.79 mm/s. Conducted a test of the selected pump in the well using a radial compensator. The magnitude of the vibration was 1.49 mm/s. Comparison of the results of the vibration values of the submersible pumping unit showed that the use of a radial compensator as part of the installation of an electrical centrifugal pump made it possible to reduce the magnitude of vibration rates by 18 %.
