Abstract
The utility model discloses a petroleum lifting pump, the main body of the pump is a pipe body (1), an L-shaped air inlet pipe (2) is installed at the lower part of the pipe body (1), the horizontal tube air-inlet of the air inlet pipe (2) is at the side wall of the pipe body (1), the upper end of the vertical tube is air outlet which connects with a nozzle (3), the nozzle end of the nozzle (3) connects with a throat (4), the throat (4) connects with the diffusion tube (5), some fuel inlet channels (7) are installed at the lower part of the pipe body (1), and one end of the fuel inlet channel (7) which stretches to the lower part of the pipe body (1) is the oil-entrance, the other end of the fuel inlet channel (7) is oil outlet which connects with the nozzle (3). The utility model accelerates the heat exchange speed and decreases the petroleum consistency greatly, which improves the petroleum fluidity obviously, meanwhile, the out and in of the petroleum is positive discharging process, which reduces the liquid resistance of the reverse discharging process and improves the speed of the petroleum discharge.
Description
Technical field:
The utility model relates to a kind of liquid lifting pump, particularly a kind of oil lifting pump.
Background technique:
Chinese patent ZL200410030531.1 discloses a kind of oil lifting pump, this pump is made up of outer tube and interior pipe, be provided with nozzle, trunnion and diffusing tube from top to bottom successively in the tube chamber in it, be provided with several oil channels between outer tube and the interior pipe, filler opening is located at outer tube top, oil outlet is in the outer tube bottom, oil flows into from filler opening, enter oil channel by oil outlet then, again from oil channel ejection suitable for reading, oil is anti-current drainage journey from entering out like this, and the petroleum liquid flow resistance is bigger, influences the velocity of discharge of oil; Because oil contains more wax or pitch mostly in the well, denseness is big, mobile poor, this infusion gas equipment injects high compressed steam from aboveground mouthful to nozzle, trunnion and diffusing tube, its heat only distributes in interior tube chamber, low with petroleum liquid rate of heat exchange in the well, can not reduce the denseness of oil effectively, improve its flowability, therefore also influence the velocity of discharge of oil.
The model utility content:
The purpose of this utility model is to provide a kind of petroleum liquid directly to discharge, and can improve the oil lifting pump of oil flow.
The technological scheme that the utility model adopted in order to achieve the above object is: oil lifting pump comprises nozzle, trunnion and diffusing tube, this pump main body is a body, L shaped suction tude is established in its body bottom, the transverse tube suction port of suction tude is positioned at tube wall, its riser upper end links to each other with nozzle, the spout end of nozzle is connected with trunnion, trunnion is connected with diffusing tube, some oil inlet passages are established in the body bottom, it is filler opening that its oil inlet passage one end extends the body bottom, and the oil inlet passage the other end is an oil outlet, and oil outlet is connected with nozzle.
As improvement project of the present utility model be: the trunnion internal diameter is less, and diffusing tube part internal diameter is bigger, and the two is connected to form conical internal cavity.
During use, the utility model is put into oil well casing, form toroidal cavity between oil well casing and the tube wall of the present utility model, inject high compressed steam from oil well is suitable for reading to toroidal cavity, steam will enter body from the suction port of body bottom, and enter nozzle successively, trunnion and diffusing tube, steam forms negative pressuren zone in nozzle, be that nozzle and oil well form pressure reduction, oil will enter from the filler opening of body bottom in the nozzle fast, and oil mixes by trunnion with steam directly discharges from diffusing tube, and oil advances like this, go out to be positive current drainage journey, reduce the anti-row's of oil liquid resistance, improved the oil velocity of discharge; In addition,, accelerated the rate of heat exchange of shaft bottom steam and oil, greatly reduced the oil denseness, obviously improved oil flow, be beneficial to petroleum liquid and discharge because steam of the present utility model is directly squeezed into the well casing bottom.Because the utility model has only a body, has saved gas transmission line, has reduced the manufacturing operation cost.
Description of drawings:
Fig. 1 is an oil lifting pump structure schematic representation of the present invention.
Fig. 2 is that A-A shown in Figure 1 is to view.
Embodiment:
As Fig. 1, shown in Figure 2, oil lifting pump of the present invention, comprise nozzle 3, trunnion 4 and diffusing tube 5, this pump main body is a body 1, L shaped suction tude 2 is established in its body 1 bottom, the transverse tube suction port 21 of L shaped suction tude 2 is positioned at body 1 sidewall, the upper end of its vertical tube is the air outlet and is connected with nozzle 3, the spout end of nozzle 3 is connected with trunnion 4, trunnion 4 is connected with diffusing tube 5 again, promptly establishes suction tude 2 in body 1 from bottom to top successively, nozzle 3, trunnion 4 and diffusing tube 5, the utility model is established some oil inlet passages 7 in body 1 bottom, it is filler opening that oil inlet passage 7 lower ends extend body 1 bottom, oil inlet passage 7 upper ends are oil outlet, and oil outlet is connected with nozzle 3, are the negative pressuren zone at enlarged nozzle 3 places, be provided with gap 6 between the air inlet nozzle place of the utility model nozzle 3 and body 1 outer wall, this gap 6 and oil inlet passage 7, nozzle 3 communicates.The utility model nozzle 3 adopts dogging shoulder to be connected with body 1 chamber, nozzle 3 is fixed on the certain position in body 1 chamber thus, be processing, easy for installation, suction tude 2 of the present utility model, nozzle 3, trunnion 4, diffusing tube 5 can be split, removable structure, suction tude 2, nozzle 3, trunnion 4, diffusion 5 pipes can shape respectively, and then the butt joint get up to put into body 1 chamber, also can earlier suction tude 2 be put into body 1 chamber, put into nozzle 3, trunnion 4, diffusing tube 5 more successively.Trunnion 4 chamber internal diameters of the present utility model are less, diffusing tube 5 diameters are bigger, trunnion 4 closely is connected to form conical internal cavity with diffusing tube 5, change nozzle 3 and trunnion 4 areas ratio, the ability to work of the utility model lifting pump is improved, for the certain nozzle 3 of area of passage, select for use trunnion 4 combinations of minor diameter to be applicable to the deep-well that lift height is big, select for use large diameter trunnion 4 combinations to be applicable to the shallow well of low lift height; The tubing employing at the utility model nozzle 3 and trunnion 4 places is wear-resistant, high temperature resistant, the GCr15 material of high pressure.
The utility model oil lifting pump also is applicable to the lifting of other liquid.
