Abstract
The utility model relates to an oil pump filter which belongs to an oil producing mechanical device in oil fields and is composed of an upper connecting head, an outer pipe, a sieving pipe, a sieving pipe head, and a lower connecting head. The sieving pipe is connected with the inner part of the lower end of the upper connecting head, the sieving pipe head is connected with the lower part of the sieving pipe, the outer pipe is connected with the lower end of the upper connecting head, and the lower part of the outer pipe is connected with the lower connecting head. A plurality of sieving slits are arranged on the sieving pipe, only fluid can pass through the sieving slits, and foreign matter in a well is blocked out of the sieving pipe. The center of the sieving pipe deviates from the center of the upper connecting head, so that the flow passage space can be centralized, and foreign matter in the well is convenient to be stored. Under the condition of not influencing the flow of fluid, the utility model can prevent foreign matter influencing oil pumps from entering the oil pumps, guarantee the regular production of the oil pumps, and extend the production time of oil wells.
Description
The utility model belongs to oil field oil recovery machiner equipment, particularly a kind of oil well pump filter.
Oil well is exploited use for a long time, has fallen into various foreign material, and as packing element etc., these foreign material are when oil pumping, can rise with fluid, be pumped in the pump, and pump inner flow passage complexity, foreign material are difficult to by the oil well pump pump valve, cause pump valve malfunctioning, can not open and close, oil well can not be produced.
Problem according to above-mentioned oil well pump existence, the purpose of this utility model provides a kind of oil well pump filter, this filter can not enter in the oil well pump foreign material that influence oil well pump not influencing under the situation that fluid flows, and has enough big parking space to deposit foreign material not stop up the fluid passage.
The purpose of this utility model is achieved through the following technical solutions.It is made up of upper connection, outer tube, screen casing, screen casing head, lower contact.Screen casing is connected in the inside of upper connection lower end, the center of the misalignment upper connection of screen casing, can concentrate flow channel space, be convenient to deposit foreign material in the well, the screen casing head is connected in the bottom of screen casing, be processed with several sieve seams on the screen casing, the sieve seam can only pass through fluid, and foreign material in the well are kept off outside screen casing, and outer tube is connected in the upper connection lower end, screen casing, screen casing head are arranged in the outer tube, and the outer tube bottom connects lower contact.Upper connection with the oil well pump filter when going into the well connects with the bottom of pump, and lower contact is with lower link oil pipe or other downhole tool.
Oil well pump filter of the present utility model, can stop that the foreign material in the oil well enter in the oil well pump, not influencing fluid enters in the pump, and the enough big space of depositing foreign material arranged, do not stop up the fluid passage, avoid the oil well operation that causes oil well pump not work to cause because of the foreign material in the oil well, can reach the purpose that prolongs the oil well production time.
Accompanying drawing is the utility model embodiment's a sectional view.
In the accompanying drawings, the 1st, upper connection, the 2nd, outer tube, the 3rd, screen casing, the 4th, the screen casing head, the 5th, lower contact, promptly the utility model is made up of upper connection 1, outer tube 2, screen casing 3, screen casing head 4, lower contact 5.From accompanying drawing, can see the utility model embodiment's the general structure and the mutual alignment relation of each parts clearly.Screen casing 3 is connected in the inside of upper connection 1 lower end, the center of the misalignment upper connection 1 of screen casing 3, can concentrate flow channel space, be convenient to deposit foreign material in the well, screen casing head 4 is connected in the bottom of screen casing 3, be processed with several sieve seams on the screen casing 3, the sieve seam can only pass through fluid, and foreign material in the well are kept off outside screen casing 3, and outer tube 2 is connected in upper connection 1 lower end, screen casing 3, screen casing head 4 are arranged in the outer tube 2, and outer tube 2 bottoms connect lower contact 5.Upper connection 1 with the oil well pump filter when going into the well connects with the bottom of pump, and lower contact 5 is with lower link oil pipe or other downhole tool.
