Abstract

Provided are an oil field oil pump sand removal device and a manufacturing method thereof. According to the technical scheme, the oil field oil pump sand removal device can be used for scraping sand,is arranged between an upper moving ball cover and an upper moving valve joint of an oil pump to enable sand in crude oil not to enter the place between a plunger and a pump cylinder, and is composedof a sand hole straight joint and a scraper ring. The sand hole straight joint is in a tube straight through shape; an upper screw opening is formed in an upper end port of the sand hole straight joint; a lower screw opening is formed in a lower end port of the sand hole straight joint; and a scraper groove is formed in the middle of the sand hole straight joint, and a sand returning hole is formed in the scraper groove. The scraper ring is in a circular ring shape and is provided with a scrapper ring seam so as to enlarge a ring opening during installation. The cross section of a ring rib isin a prism shape, the inner diameter wall of the ring rib is low, the outer diameter wall of the ring rib is high, and two cutting edges are formed up and down. The oil field oil pump sand removal device has the advantages of solving the blockage and stopping problems caused by sand sediment in the crude oil on the plunger of the oil pump and improving the working efficiency of the oil pump.

Description

technical field [0001] The invention relates to a manufacturing method of an oilfield oil recovery equipment accessory. , especially an oil field oil pump sand cleaner and a manufacturing method thereof. Background technique [0002] The oil pump is a common oil pumping equipment for pumping the crude oil in the well to the ground. The existing oil pump mainly consists of an upper moving ball cover, an upper sealing ball, an upper sealing ball seat, an upper fixed valve joint, and an upper moving valve joint. , plunger, pump barrel, middle-swimming valve cover, middle sealing ball, middle sealing ball seat, sealing seat cover, middle fixed valve joint, lower fixed valve cover, lower sealing ball, lower sealing ball seat, lower fixed valve joint The oil pumping method is to lift the crude oil from a low place to a high place through the up and down movement of the plunger and pump the crude oil from the bottom of the well to the top of the well and out of the well, because t...
