Problems solved by technology

[0002] At present, in the sand control separator used on oil wells, the sand control filter screen is covered on the sand control inner tube. Although there is a certain gap between the sand control filter screen and the sand control inner tube, the sand control filter screen is easily absorbed by the pump for a certain period of time. On the sand control inner pipe, the filter area of ​​the sand control filter is reduced, and the suction force of the sand control filter is increased. The filter screen of the oil inlet channel with a small area is easily damaged by the suction of the oil well pump, and the filter screen is easy to lose. Filtration, fine silt enters the pump barrel through the damaged filter, causing the pump to stop production and shorten the separation effect of the separator

Abstract

The invention discloses a high-efficient multi-stage cyclone self-cleaning separator and an application method, relates to the sand control technique of oil well pumps and solves the problems in the prior art. The structural relationship of the separator lies in that an upper connector is connected to the upper end of an outer tube, and a lower connector is connected to the lower end of the outer tube; an inner tube is arranged in the middle of the outer tube; spring supports are respectively fixed on the periphery of the inner tube; big ends of springs are fixed on the spring supports; small ends of the springs are fixed on upper fixed rings, slip rings are arranged on the periphery of the inner tube, filter screens are arranged at the outer ends of the springs, the upper ends of the filter screens are fixed on the peripheries of the slip rings by filter screen small hoop rings, and the lower ends of the filter screens are fixed on the peripheries of the spring supports by filter screen large hoop rings.

Description

technical field [0001] The invention relates to sand control technology of an oil well pump, in particular to a multi-stage high-efficiency cyclone self-cleaning separator and an application method. technical background [0002] At present, in the sand control separator used on oil wells, the sand control filter screen is covered on the sand control inner tube. Although there is a certain gap between the sand control filter screen and the sand control inner tube, the sand control filter screen is easily absorbed by the pump for a certain period of time. On the sand control inner pipe, the filter area of ​​the sand control filter is reduced, and the suction force of the sand control filter is increased. The filter screen of the oil inlet channel with a small area is easily damaged by the suction of the oil well pump, and the filter screen is easy to lose. Filtration, fine silt enters the pump barrel through the damaged filter screen, causing the pump to stop production and sh...
