Abstract
The utility model relates to a two-purpose thick oil well pump for gas injection and oil pumping, belonging to the improvement of a tubular pump in oil well pumps in oil machinery. The timely opening and closing of the pump and the reliability of gas injection and oil draining can be realized by using a three-purpose joint for injecting, pumping and draining and by using the structure of a plug valve for forcible opening and closing. The utility model is mainly composed of a free assembly, a pump cylinder, the three-purpose joint for injecting, pumping and draining, and a standing valve assembly.
Description
The utility model relates to a kind of novel notes vapour dual-purpose suction pump of pumping, and it is the improvement that belongs to the tubing pump in the oil well pump in the petroleum machinery.It is to take out the reliability that the stifled valve arrangement of letting out three usefulness joints and adopting forced opening-closing is realized the timely opening and closing of pump and annotated the vapour draining by adopting to annotate.It mainly is that move about assembly, pump barrel, notes taken out and let out three usefulness joints and the standing valve assembly constitutes.
At present, employed oil well pump mainly contains the branch of tubing pump and sucker rod pump in the petroleum development engineering.The pump barrel of tubing pump directly is connected the lower end of oil pipe, and remove with oil pipe, its plunger links to each other with rod string, and remove with rod string, this pump is widely used in the Development Engineering of oil greatly because of its discharge capacity, but the rountrip amount of this pump is big, need rod string and tubing string mentioned respectively just and can trip out oil well pump, because its draining is incomplete or the draining failure also usually causes near the environmental pollution in well site, this has not only wasted crude oil, also makes operating worker very arduous.And removing of sucker rod pump is simpler than tubing pump, and entire pump can remove with rod string, but under same production string diameter, its discharge capacity is little than tubing pump, thereby this pump is used less in China at present.When production of heavy oil reservoir, also need in oil well, to inject hot steam every now and then to reduce the viscosity of crude oil.When annotating vapour, to trip out rod string and plunger to tubing pump, and the bailing standing valve, its workload is bigger.At present, used traditional oil well pump all is that traveling valve and standing valve are arranged in the oil development industrial and mineral, because the spatial motion of valve is extremely complicated, the untimely filling index of pump that then can cause of the switch of valve reduces, and causes pump delivery to reduce.
The purpose of this utility model provides a kind of notes vapour that vapour can pump dual-purpose suction pump of pumping of both can having annotated with regard to being to avoid above-mentioned the deficiencies in the prior art part.It is that the tubing pump of routine is reequiped a little, adds to annotate to take out to let out three usefulness joints and realize that it annotates vapour oil pumping and need not the purpose of pump.It mainly is by the assembly that moves about, pump barrel (2), annotates to take out and let out three usefulness joints and standing valve assembly formation, its major technology characteristics component placement (2) in pump barrel that is to move about, take out with notes then and let out three usefulness joints, the standing valve assembly is in series successively, and be coupled to each other respectively by the screw thread screw thread.
Accompanying drawing is structural representation of the present utility model.
In order to realize above-mentioned purpose of the present utility model better, artificer of the present utility model then takes out notes and lets out three usefulness joint design one-tenth is to be series at the interior structural type of joint housing (13) successively by upper tooth body (8), lower tooth body (9), sealing body (11), thrust bearing (10), return spring (12) and spring seat (20), the middle part of its joint housing (13) offers annotates vapour draining hole (21), also offers corresponding notes vapour draining hole (21) respectively on its sealing body (11) and the spring seat (20); The lower end of its return spring (12) is located on the spring seat (20), and sealing body (11) is being supported in its upper end, is provided with thrust bearing (10) at sealing body (11) with lower tooth body (9) place of linking; Its assembly that moves about that is placed in the pump barrel (2) also is to be designed to be the structural type that is in series successively by adapter coupling (3), connecting rod (4), pressure cover (19), sliding piston (5), stifled valve seat (6) and stifled valve (7), the upper end of its connecting rod (4) is connected in adapter coupling (3), lower end and stifled valve (7) link, after the series connection move about assembly then integral body be arranged in the pump barrel (2), upper end of its pump barrel (2) and top sub (1) link by screw thread, and the lower end is then taken out with notes and let out three usefulness joints and link by screw thread; The standing valve assembly then is to be made of standing valve cover (22), location body (16), special box cupling (15), fixed valve ball (14) and bottom joint (18), its fixed valve ball (14) is arranged on the fixed valve base (17), and place in the location body (16), the upper end of fixed valve ball (14) is provided with standing valve cover (22), totally place then in the special box cupling (15), the lower end of its special box cupling (15) and bottom joint (18) link by screw thread.
The drawing of accompanying drawing is described as follows:
1---top sub 2---pump barrel 3---adapter coupling 4---connecting rod
The stifled valve 8---upper tooth body of the stifled valve seat 7---of 5---sliding piston 6---
9---lower tooth body 10---thrust bearing 11---sealing body 12---return spring
The special box cupling 16---of 13---joint shell 14---standing valve 15---location body

21---draining hole 22---standing valve cover
Come enumeration design feature of the present utility model below in conjunction with drawings and Examples:
In actual design with in making, artificer of the present utility model is that the tubing pump that will have the utility model structural feature is designed to be made of three parts, and the promptly inner pump barrel part that is provided with the assembly that moves about (mainly comprises adapter coupling, connecting rod, press cover, sliding piston, stifled valve seat and stifled valve etc.), notes are taken out and are let out three usefulness joint parts and (mainly comprise the upper tooth body, the lower tooth body, thrust bearing, the sealing body, return spring and spring seat etc.) and the standing valve assembly part (mainly comprise standing valve cover, the location body, special box cupling, fixed valve ball, fixed valve base and bottom joint etc.).Then, the structure installation according to accompanying drawing forms.Like this, take out draining problem when letting out three usefulness joints and having solved that tubing pump plays pump, make its reliable operation, and simply rod string just can all release the oil in the oil pipe to only transferring with notes.In addition, because the particularity of this structure, it can not realize that also pump just can annotate the purpose of vapour: when annotating vapour, only need transfer rod string, notes vapour is over rod string is upwards transferred again and can normally have been pumped once carrying.Replace traveling valve with stifled valve and sliding piston, pressure makes it in time to open and in time closes, thereby has reduced the discharge capacity that hysteresis and leakage the caused loss of valve, has increased pump delivery.The pressure cover on its pump top also has the effect of strike-ofing, and can reduce the wearing and tearing of sand to the pump component.
Because special construction of the present utility model, make it to have possessed above-mentioned advantage, compare with oil well pump of the prior art, when only annotating vapour and the operation during draining, just can reduce about about 10,000 yuan of operation cost at every turn.Simultaneously, again because its whole pump structure is simple, easy to process, cheap, so great market prospects and promotional value are arranged.
