Abstract
The utility model relates to an antiscale oil exploitation pump which comprises a pump body (1), a plunger (4), a movable valve ball (9) and a fixed valve ball (10). An outer cover (11) is fixed at the upper end of the fixed valve ball (10), the lower end of the outer cover (11) is connected with a lower coupling (3), the plunger (4) is arranged on the inner wall of the pump body (1), the plunger (4) is connected with a core tube (7), a groove is formed in the core tube (7), and a scraping ring (12) is arranged inside the groove. Due to the fact that an upper opening and a chamfering structure are arranged at the upper end of the open plunger of the upper portion of the pump, the possibility that subsiding sand enters a seal clearance is reduced to a maximum extent, full-stroke contact type scraping is carried out to the inner wall of the pump body by utilizing a nonmetal scraping ring structure, sand and dirt are effectively prevented from being formed and accumulating on the inner wall of a pump barrel, and therefore the adaptability of an oil well pump on a sandy well and a scaling well is effectively improved, and the aim of prolonging a pump detection period is achieved.
Description
Technical field
The utility model relates to a kind of petroleum production pump, relates in particular to a kind of antiscale petroleum production pump, belongs to oil-field oil pumper oil recovery technique field.
Background technique
Oil is the indispensable energy of modern social development or resource, and oil can be divided into the various products such as gasoline, aviation kerosine, diesel oil, machine oil through exploitation with after refining, for nearly all machines such as automobile, aircraft, steamer provide the energy.
Oil is can form through tens million of years, thereby it is to form from process corruptions such as Paleozoic trees.General oil all buries under underground or seabed, with oil at the bottom of the ground or offshore mining out, need various device and device.The petroleum production pump is the main core apparatus of recover petroleum; the production pump that existing oilfield uses; plunger in the pump barrel is common plunger; containing dirt, containing in the recovery process of sand oil recovery well; plunger and pump barrel all can cause partial wear; when plunger is up and down reciprocatingly twitched in pump barrel; the meeting that can not wall exempt from gap in the oil well pump system between pump barrel and the plunger enters dirt grain or sand grains; the easy like this stuck phenomenon of pump barrel and plunger that causes occurs; thereby brought adverse effect for the normal production of oil well, seriously restricted the benefit of oil field development.These petroleum production pump simplicity of design of while, structure is very original, all haves much room for improvement on production efficiency and function, and along with continuous complicated and abominableization of the environment of petroleum production, traditional petroleum production pump has not adapted to modern petroleum production environment gradually.
The model utility content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of antiscale petroleum production pump, comprise the pump housing, plunger, travelling valve ball and standing valve ball, standing valve ball upper end is fixed with outer cover, the outer cover lower end is connected with lower box cupling, and plunger is arranged on pump housing inwall, and plunger is connected with the core pipe, in described core pipe, be provided with groove, the scraping ring is installed in the groove.
Preferably, above-mentioned pump body is provided with pull bar.
Preferably, above-mentioned pull bar is connected with valve bonnet.
Preferably, above-mentioned core pipe lower end is disposed with lower valve bonnet, travelling valve ball and pipe close.
Preferably, above-mentioned plunger is connected with described core pipe by described upper valve bonnet.
Preferably, the upper end of the above-mentioned pump housing is fixedly connected with box cupling.
The antiscale petroleum production pump that the utility model provides is by upper opening and chamfering structure on the open plunger that is arranged on top, at utmost reduce the possibility that the sedimentation sand grains enters seal clearance, and utilize nonmetal scraping ring structure, pump housing inwall is carried out the scraping of full stroke contact-type, effectively stop sand and formation and the accumulation of dirt at the pump barrel inwall, thereby effectively improve this oil well pump to shake out, the adaptability of fouling oil well, reach the purpose that prolongs pump detection period.
Description of drawings
Fig. 1 is the utility model structural representation.
Mark among the figure: the 1-pump housing; The upper box cupling of 2-; Box cupling under the 3-; The 4-plunger; The upper valve bonnet of 5-; Valve bonnet under the 6-; 7-core pipe; The 8-pipe close; 9-travelling valve ball; 10-standing valve ball; The 11-outer cover; 12-scraping ring; The 13-pull bar.
Embodiment
Understand and enforcement the utility model for the ease of those of ordinary skills, below in conjunction with the drawings and the specific embodiments the utility model is described in further detail.
Antiscale petroleum production pump as shown in Figure 1, comprise the pump housing 1, plunger 4, travelling valve ball 9 and standing valve ball 10, standing valve ball 10 upper ends are fixed with outer cover 11, outer cover 11 lower ends are connected with lower box cupling 3, plunger 4 is arranged on the pump housing 1 inwall, plunger 4 is connected with core pipe 7, is provided with groove in described core pipe 7, and scraping ring 12 is installed in the groove.The pump housing 1 inside is provided with pull bar 13.Pull bar 13 is connected with valve bonnet 5.Core pipe 7 lower ends are disposed with lower valve bonnet 6, travelling valve ball 9 and pipe close 8.
In the oil well pump work, during upstroke, open plunger 4 forms sealing with the pump housing 1, the opening upwards of the plunger 4 of opening, and top is chamfering structure, can prevent effectively that like this sand and dirt from entering seal clearance; Simultaneously, in upstroke and down stroke, along with pumping of open plunger 4, can in the annular groove of core pipe 7, form pressure reduction, scraping ring 12 is under the effect of this pressure reduction, the pump barrel inwall is carried out the scraping of full stroke contact-type, be in constantly by the sand grains in the fluid of agitated conditions and dirt grain and can be deposited in the pump housing 1, can prevent effectively that dirt and sand are in formation and the accumulation of pump barrel inwall.
Usually, the pump housing 1 and plunger 4 have metal cladding, and scraping ring 12 can be made with nonmetallic material, and the scraping that can reduce like this 12 pairs of pump housing 1 inwalls of scraping ring and plunger 4 destroys.
The antiscale petroleum production pump that the utility model provides is by upper opening and chamfering structure on the open plunger that is arranged on top, at utmost reduce the possibility that the sedimentation sand grains enters seal clearance, and utilize nonmetal scraping ring structure, pump housing inwall is carried out the scraping of full stroke contact-type, effectively stop sand and formation and the accumulation of dirt at the pump barrel inwall, thereby effectively improve this oil well pump to shake out, the adaptability of fouling oil well, reach the purpose that prolongs pump detection period.
The embodiment of the above is better embodiment of the present utility model; be not to limit implementation scope of the present utility model with this; scope of the present utility model comprises and is not limited to this embodiment, and the equivalence that all shapes according to the utility model, structure are done changes all in protection domain of the present utility model.
