Abstract
The utility model belongs to an oil pump, more particularly relates to a sand scraping and rotating oil pump which comprises an upper joint, an pumping rod short connection, a sand rotating sheet, a sand scraping sheet, a piston assembly, a pump cylinder, a travelling valve assembly and a bottom valve. The sand scraping and rotating oil pump is characterized in that that the upper joint is connected with the pump cylinder, the pump cylinder is connected with the bottom valve, and the pumping rod short connection is provided with the sand rotating sheet and the sand scraping sheet and is connected with the piston assembly and the travelling valve assembly. The utility model has the advantages that the abrasion between a plunger and the pump cylinder is reduced, and the oil production period of a sanding production well is prolonged.
Description
Technical field
The utility model belongs to a kind of oil well pump, and particularly a kind of strike-ofing revolved the sand oil well pump.
Background technique
At present, conventional tubular type and rod-type pumping unit in China's field use are as main lifting instrument, increase along with oilfield exploitation intensity, the sand production problem is more and more serious, become gradually and cause oil well pump to lose efficacy, mainly show as phenomenons such as sand card plunger, sand milling plunger and wearing and tearing pump barrel, cause effective manufacture cycle of oil well to shorten, operation is frequent, and cost of production rises significantly.
Summary of the invention
In order to overcome the problems referred to above, the utility model provides a kind of strike-ofing to revolve the sand oil well pump, and this strike-ofing revolved the sand oil well pump, when sucker rod is worked up and down, revolves the sand sheet, the sheet of strike-ofing rotates thereupon and move up and down, and the sand grains rotation is flowed with well liquid, reduces sand card phenomenon.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of strike-ofing revolved the sand oil well pump, by upper connection, sucker rod short circuit, revolve the sand sheet, the sheet of strike-ofing, piston assembly, pump barrel, travelling valve assembly and bottom valve form, its special way is: upper connection connects pump barrel, pump barrel is connected with bottom valve, be equipped with on the sucker rod short circuit revolve the sand sheet, the sheet of strike-ofing, the sucker rod short circuit connects piston assembly and travelling valve assembly.
The beneficial effects of the utility model are: slow down the wearing and tearing between plunger and pump barrel, prolong the oil recovery manufacture cycle of sand well.
