Description
Technical field
The utility model relates to a kind of oil well pump, particularly a kind of ultra-long-stroke oil well pump.
Background technique
At present, in field of petroleum exploitation, in order to improve oil production, some oil well needs to use ultra-long oil well pump to exploit, but conventional oil well pump enter well mode, enter under not being suitable for overlength pump, enter directly if think, then how long oil well pump must need workover derrick how long, sometimes limit by terrian condition, adopt routine to enter well mode overlength pump and cannot enter well at all, and ultra-long oil well pump used needs to use professional tool to block pump barrel and pump barrel connecting hoop links together upper and lower pump barrel when mounted at present, more time-consuming, effort, significantly reduce the operating efficiency of oil well.
Summary of the invention
The purpose of this utility model not easily enters time-consuming in well and installation process, effort to solve some overlength oil pumps used in existing petroleum production industry, causes the problem that oil well operation efficiency reduces and a kind of ultra-long-stroke oil well pump provided.
The ultra-long-stroke oil well pump that the utility model provides includes pump barrel and lower pump barrel, the left end wherein going up pump barrel is connected with the first pump barrel joint, the first pump barrel connecting hoop is connected with between upper pump barrel and lower pump barrel, the right-hand member of lower pump barrel is connected with the second pump barrel connecting hoop, the right-hand member of the second pump barrel connecting hoop is connected with the second pump barrel joint, and the right-hand member of the second pump barrel joint is connected with standing valve ball assembly.
The left end of the first pump barrel joint is connected with pull bar by supporting positive cover.
Plunger piston assembly is inserted with in upper pump barrel.
The two ends of the first pump barrel connecting hoop and the second pump barrel connecting hoop are equipped with locking nut, and the first pump barrel connecting hoop and the second pump barrel connecting hoop are undertaken fastening by locking nut.
Installation principle of the present utility model:
First lower pump barrel is connected with standing valve ball assembly with the second pump barrel joint successively by the second pump barrel connecting hoop, then G.I.H is suspended on wellhead flange by elevator, again the right-hand member of the first pump barrel connecting hoop is carried out locking by locking nut with the left end of lower pump barrel to be connected, upper pump barrel is fastenedly connected the left end at the first pump barrel connecting hoop by locking nut, then the left end going up pump barrel connects the first pump barrel joint again, from then on analogizes the some joints of connection and reaches use length.
The beneficial effects of the utility model:
The ultra-long-stroke oil well pump that the utility model provides is the overlength pump barrel be connected to form successively by multiple pump barrel unit, and there is the standing valve ball assembly be connected with oil pipe in oil well the upper end of this pump barrel.Several adjacent pump barrel connects the length requirement reaching ultra-long-stroke oil well pump in this way, and structure is simple, easy to operate, connects reliable, is fit into well ratio and is easier to, compare save time, laborsaving, drastically increase the operating efficiency of oil recovery well.
