Abstract
The utility model provides a high-sealing double-action oil pump aiming to solve the problems of low pump efficiency and high power consumption of the oil pump in the prior art. The oil pump is characterized in that the lower part of a sucker rod (4) is connected to a hollow internal upper sealing plunger (7) via a top traveling valve cover (5), a bottom traveling valve (13) is arranged between the upper sealing plunger (7) and a lower sealing plunger (14) at the bottom of the oil pump, an oil pipe (3) at the bottom of the lower sealing plunger (14) is provided with a bottom fixing valve (15), an upper sealing cylinder (10) is arranged on the external side of the upper sealing plunger (7), the external side of the upper sealing cylinder (10) is fixed with an upper stroke draining device (8), the lower part of the upper stroke draining device (8) is provided with a lower stroke draining device (11). both of the upper and lower strokes of the high-sealing double-action oil pump can be used to pump oil, therefore the oil pump in the utility model has the characteristics of high pump efficiency, low power consumption and safe running.
Description
Technical field
The utility model relates to the used oil production equipment in a kind of oil field, especially belongs to a kind of high sealing double acting sucker rod pump.
Background technique
In the oilfield exploitation later stage, oil well pump is the oil production equipment of using always, and existing oil well pump is owing to pump when having only upstroke, and down stroke space-time is sailed, so pump efficiency is low, and power consumption is big.
Summary of the invention
[0003] in order to solve the problem that existing oil well pump pump efficiency is low, power consumption is big, the utility model provides a kind of high sealing double acting sucker rod pump, the upper and lower stroke of this high sealing double acting sucker rod pump all can be pumped, and has that pump efficiency height, power consumption are little, the characteristics of security of operation.
The technical solution of the utility model is: a kind of high sealing double acting sucker rod pump, comprise sucker rod, described sucker rod bottom connects the last sealed plunger of inner hollow by the top valve bonnet that moves about, be equipped with the bottom travelling valve between the lower seal plunger of last sealed plunger and its bottom, be equipped with the bottom standing valve on the oil pipe of lower seal plunger bottom, the described cold upper seal bore that is fixed with of sealing column of going up, upper seal bore external stability has upstroke oil extraction device, upstroke oil extraction device valve is arranged on the described upstroke oil extraction device, upstroke oil extraction device bottom is equipped with the down stroke oil feeder, and down stroke oil extraction device valve is arranged on the described down stroke oil feeder.
The utlity model has following beneficial effect: owing to take such scheme, last sealed plunger inner hollow, during down stroke in the pump well liquid can pass to ground well head output terminal by inner the making progress to the annular space of oil pipe and sucker rod of last sealed plunger; The bottom standing valve is opened during stroke, and travelling valve is closed, and well liquid passes to ground by the annular space of oil pipe and sucker rod.Like this, this oil well pump up-down stroke can be pumped, and has improved pump efficiency greatly, has relatively just reduced power consumption, and upper and lower sealed plunger formation double-sealing, makes sealing more reliable, moves safer.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
1-polished rod among the figure, 2-well head output terminal, 3-oil pipe, 4-sucker rod, the 5-valve bonnet that moves about at the top, 6-top travelling valve, the last sealed plunger of 7-, 8-upstroke oil extraction device, 9-upstroke oil extraction device valve, the 10-upper seal bore, 11-down stroke oil feeder, 12-down stroke oil feeder valve, 13-bottom travelling valve, 14-lower seal plunger, 15-bottom standing valve.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, a kind of high sealing double acting sucker rod pump, comprise sucker rod 4, also comprise the top valve bonnet 5 that moves about, last sealed plunger 7, upstroke oil extraction device 8, upper seal bore 10, down stroke oil feeder 11, lower seal plunger 14, bottom standing valve 15, sucker rod top connects polished rod 1, sucker rod 4 bottoms connect the last sealed plunger 7 of inner hollow, and the top valve bonnet 5 that moves about is arranged between sucker rod 4 and the last sealed plunger, moving about in the top has the top travelling valve in the valve bonnet 5, last sealed plunger 7 bottoms connect lower seal plunger 14, the lower seal plunger respectively has a bottom travelling valve 13 in two ends about in the of 14, be equipped with end standing valve 15 on the oil pipe 3 of lower seal plunger 14 bottoms, there is upper seal bore 10 described cold 7 outsides of sealing column of going up, and between the two slidably, upper seal bore 10 external stabilities have upstroke oil extraction device 8, upstroke oil extraction device valve 9 is arranged on the described upstroke oil extraction device 8, well liquid can flow from the bottom to top by upstroke oil extraction device valve 9, upstroke oil extraction device 8 bottoms are equipped with down stroke oil feeder 11, down stroke oil feeder valve 12 is arranged on the described down stroke oil feeder 11, and the well liquid between oil pipe 3 and the sleeve pipe can enter on the oil pipe 3 between the sealed plunger 7 by down stroke oil feeder valve 12.
During down stroke, top travelling valve 6 and bottom travelling valve 13 are all opened, bottom standing valve 15 is closed, because plunger moves downward, make upper and lower sealed plunger (7,14) space between increases, pressure reduces, thereby down stroke oil feeder valve 12 is opened under the pressure effect of extraneous well liquid, and upstroke oil extraction device valve 9 is closed, the outer well liquid of pump enters in sealed plunger 7 hollow stems by bottom travelling valve 13, and upwards the annular space to oil pipe and sucker rod passes to ground well head output terminal 2; During upstroke, top travelling valve 6 and bottom travelling valve 13 are closed, bottom standing valve 15 is opened, simultaneously, down stroke oil feeder valve 12 is closed, and upstroke oil extraction device valve 9 is opened, well liquid is promoted to ground well head output terminal 2 by plunger in the pump, simultaneously, the well liquid of oil sets annular space is by in bottom standing valve 15 suction pumps, for next circulation is prepared.Briefly, well liquid is upwards carried by plunger cavity during down stroke, and therefore well liquid, realized that upper and lower stroke all pumps by the upwards conveying of annular space of plunger and oil pipe during upstroke, and pump efficiency is improved greatly.Simultaneously, upper seal bore 10 and last sealed plunger 7 and pump barrel and lower seal plunger 14 form the sealing of two places respectively, make sealing more reliable, also make simultaneously this oil well pump form two independently seal operation chambeies, these two active chambers cooperate oil-feed, oil outlet separately, make this oil well pump possess double-acting characteristic.
The produced on-site test shows, when being replaced with new pump by existing pump, each equipment of pumping unit system all need not change, just the pump type can be than the little model of former pump, and replaceable as former 57 pumps is new 44 pumps, and power consumption decline has made an appointment with 30% under the situation that keeps former output, energy-saving and emission-reduction have been realized, simultaneously, as the pump with same model, then output can improve greatly.
