Description

Technical Field

[0001] The utility model belongs to the technical field of oil extraction, and particularly relates to a self-cleaning sand filter pipe pumping device. Background Art

[0002] China is rich in oil resources. However, the environments of some oil reservoirs are relatively harsh, resulting in excessive impurities in the oil, such as sand, water, various gases and other impurities. When extracting oil, a sand filter pipe is used to preliminarily filter the sand in the oil, and then the oil is pumped to the processing center on the ground for further treatment of other impurities in the oil.

[0003] In the related art, a sand filter pipe is disclosed, which includes an outer protection base pipe, a base pipe and a filtering mechanism. The base pipe is fixedly installed inside the outer protection base pipe, and the filtering mechanism is arranged inside the base pipe. The filtering mechanism is composed of a stainless steel pipe, a mounting block, a filter screen, a connecting rod, a spring rod and a pull rod. In the process of oil well exploitation, the stainless steel pipe will hinder the upward penetration of the ground sand layer, and the ground sand layer will pour in from the sand holes on the outer surface of the stainless steel pipe. The filter screen inside the stainless steel pipe can hinder the upward movement of the ground sand. By arranging multiple layers of filter screens, when the pressure difference inside and outside the filter screen is large and the filter screen is damaged, the formation sand can be prevented from entering the base pipe, causing sand burial of the base pipe and preventing the normal production of the oil well. By setting a corrosion-resistant layer on the outer wall of the outer protection base pipe, soil erosion of the outer protection base pipe can be reduced, long-term shutdown and maintenance of the oil well can be avoided, and the service life can be increased.

[0004] However, there are still deficiencies in the above structure. When the sand filter pipe is in use, sand and gravel are easily stuck in the filter holes of the sand filter pipe, resulting in blockage of the filter screen and reduction of the filtering effect on the oil.

[0005] Therefore, it is necessary to provide a new self-cleaning sand filter pipe pumping device to solve the above technical problems. Summary of the Utility Model
