One, technical field: the utility model relates to oil field operation machinery, and especially a kind of novel survey is penetrated connection and made oil well pump.
Two, background technique: the survey of using in the oil well is at present penetrated connection and mainly contained following shortcoming as oil well pump: 1, adopt overall fixed valve throw-in type, such structure diminishes oil flow channel, and pumping efficiency reduces, and it is unreliable to seal; 2, pump barrel does not have outer protection of pipe, the yielding holddown that causes when pump barrel is subjected to bigger pulling force; 3, oil outlet easily is deposited on the dirt on the tubing wall, wax etc. in the standing valve when being lowered to sucker rod on standing valve top, causes ball valve to block.
Three, summary of the invention: it is reliable that the purpose of this utility model provides sealing, long a kind of novel survey of life-span is penetrated connection and is made oil well pump, it has overcome the shortcoming of other technology, the purpose of this utility model is to realize like this, it is by upper connection, upper traveling valve cage, supporting positive cover, upper travelling valve, two tool joint pins, pump barrel, outer tube, plunger, the lower travelling valve cover, lower travelling valve, pressure cap moves about, sub-coupling, the standing valve shell, the clamp mandrel, flow tube, clamp, spring, limited cap, standing valve cover, fixed valve ball, " O " type circle, fixed valve base, lower contact is formed by connecting, upper connection is connected with external pipe thread, the outer tube lower end is threaded with sub-coupling, forms outer pipe assembly.
Upper travelling valve is installed in the upper traveling valve cage, two tool joint pins and upper travelling valve are by being threaded, upper travelling valve is limited in the cover that moves about, two tool joint pins and plunger are by being threaded, the plunger lower end is threaded with the lower travelling valve cover, the traveling valve pressure cap is threaded with the lower travelling valve cover, and lower travelling valve is limited in the lower travelling valve cover, forms plunger piston assembly.
Supporting positive cover is threaded with pump barrel, the pump barrel lower end is connected with the standing valve outer casing screw, flow tube is threaded with standing valve cover, a plurality of apertures are arranged on the flow tube, from then on oil flow, and the hole enters pump barrel, individual circular groove is arranged on the inwall of flow tube, this groove can cooperate with the groove on the clamp, two " O " type circles are arranged on the standing valve cover, have four elongated slots on the step outer wall, oil flows thus that groove enters, standing valve cover is connected with the standing valve outer casing screw, standing valve cover is threaded with lower contact, and fixed valve base is limited in the standing valve cover, forms the pump barrel assembly.
Three clamps are installed on the clamp mandrel, mounting spring between clamp and the clamp mandrel, clamp mandrel two ends are equipped with limited cap, and clamp is positioned on the clamp mandrel, form the clamp assembly.
The pump barrel assembly is threaded by sub-coupling with outer pipe assembly, and fixed valve ball is positioned on the fixed valve base of standing valve cover.
During work, the pump barrel assembly is threaded by sub-coupling with outer pipe assembly, fixed valve ball is positioned on the fixed valve base of standing valve cover and (takes out fixed valve ball and clamp assembly this moment, pump barrel is communicated with up and down, can be by test instrument and perforation rod), lower contact is lowered to designed depth with linking to each other with perforating gun by oil pipe, be lowered to test instrument and accurately test the position of perforating gun, after determining, the position of perforating gun trips out test instrument, drop into the perforation rod from well head, trigger the perforating gun perforation, drop into fixed valve ball after perforation is finished, pipe is tested in pressure testing, when testing the qualified back input clamp of pipe assembly, when the clamp assembly enters flow tube, be stuck on the step of flow tube, thereby fixed valve ball is limited in the valve bonnet, is lowered to plunger and begins oil pumping work.
Meaning of the present utility model: the one, adopt stuff, sealing is reliable, and oil flow channel increases; The 2nd, pump barrel has protective tube outward, and former tube is not subjected to the influence of pulling force, long service life; The 3rd, sand setting is difficult for valve ball is stopped up in the oil pipe on pump top; The 4th, survey, penetrate connection and do, avoid strata pressure to change and the unsafe factor that brings, protect oil reservoir effectively.
Four, description of drawings: Fig. 1 penetrates connection for a kind of novel survey and makes the structural representation of oil well pump, among the figure 1, upper connection 2, upper traveling valve cage 3, supporting positive cover 4, upper travelling valve 5, two tool joint pin 6, pump barrel 7, outer tube 8, plunger 9, lower travelling valve cover 10, lower travelling valve 11, traveling valve pressure cap 12, sub-coupling 13, standing valve shell 14, clamp mandrel 15, flow tube 16, clamp 17, spring 18, limited cap 19, standing valve cover 20, fixed valve ball 21, " O " type circle 22, fixed valve base 23, lower contact
