Description
Technical field
The utility model relates to oil extraction in oil field field oil pumping machine oil pumping pump used auxiliary device, especially oil pump enhancing device.
Background technique
In the oil extraction in oil field field, oil well pump is important oil recovery well lifting equipment.Oil well pump is comprised of pump barrel, plunger and valve valve.When plunger was up, the travelling valve valve cut out, and the plunger lower space produces negative pressuren zone, is full of the liquid of negative pressuren zone from two aspects, and the one, the standing valve valve that liquid backs down under the pump in the pit shaft enters negative pressuren zone, and this is our needs.The 2nd, the gap of plunger and pump barrel is also so that the liquid that has risen in the oil pipe column oozes the negative pressuren zone of getting back to the plunger bottom, this is a large reason that reduces pump, what are directly proportional with pressure is not of uniform size the gap length of pump and plunger top the amount of oozing back, the larger pressure in gap is larger, and the amount of oozing back is also just larger.The liquid that oozes back by the gap of plunger and pump barrel, produces atomizing under High Pressure, be full of rapidly the negative pressuren zone of plunger bottom, and it is stifled to form vapour lock, occupies space in the oil well pump, and pump efficiency generally reduces by 13% to 27% along with reduction, finally affects the Annual output in oil field.。
Summary of the invention
In order to solve the stifled problem of existing oil well pump vapour lock.The utility model provides a kind of oil pump enhancing device.This oil pump enhancing device can improve the oil well pump working environment, and it is stifled to eliminate the oil well pump vapour lock, increases the oil well pump pumping efficiency.
The technical solution of the utility model is: this oil pump enhancing device comprises central shaft, valve seat and unsteady valve cover.The sucker rod upper end of oil well pump upper end is connected with 1 above central shaft in turn, the central shaft upper and lower end has respectively upper connection and lower contact, axially have 2-3 guiding gutter on the central shaft between upper connection and the lower contact, valve seat is connected on the central shaft of lower contact upper end, slidely connects the valve cover that floats more than 1 on the central shaft of valve seat upper end.
Guiding gutter in the such scheme is 3; The valve cover that floats is 5.
The utlity model has following beneficial effect: this oil pump enhancing device is owing to adopt the sucker rod upper end of oil well pump upper end to be connected with 1 above central shaft in turn, the central shaft upper and lower end has respectively upper connection and lower contact, axially have 2-3 guiding gutter on the central shaft between upper connection and the lower contact, valve seat is connected on the central shaft of lower contact upper end, slidely connects the structure of the valve cover that floats more than 1 on the central shaft of valve seat upper end.When pumping unit works, this oil pump enhancing device and oil pump plunger piston synchronous operation, when oil pump plunger piston is up, utilize valve seat and cooperating that unsteady valve overlaps, close guiding gutter, simultaneously by unsteady valve overlap with oil pipe in cooperate, produce suction, and then reduce oil well pump top pressure, the formation negative pressuren zone is effectively controlled liquid and is oozed backflow, eliminate atomizating phenomenon, the plunger working space all fills up liquid when making oil well pump up, and then improves pump efficiency, increases pumping well output, generally bring up to 2-5 doubly, and structure and installation are simple.This oil pump enhancing device can be eliminated the oil well pump vapour lock and block up increase oil well pump pumping efficiency thus.And structure and installation are simple.This oil pump enhancing device can improve the oil well pump working environment thus, and it is stifled to eliminate the oil well pump vapour lock, increases the oil well pump pumping efficiency.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
1-central shaft among the figure, 2-valve seat, the 3-valve cover that floats, 4-upper connection, 5-lower contact, 6-guiding gutter, 7-oil well pump, 8-sucker rod.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in the figure, this oil pump enhancing device comprises central shaft 1, valve seat 2 and unsteady valve cover 3.Sucker rod 8 upper ends of oil well pump 7 upper ends are connected with 1 above central shaft 1 in turn, according to well depth, can be connected with 1 central shaft 1 in first segment sucker rod 8 upper ends of oil well pump 7 upper ends, can also be connected with again 1 central shaft 1 in second section sucker rod 8 upper ends of oil well pump 7 upper ends again, according to the well depth design by that analogy.There is upper connection 4 central shaft 1 upper end, and there is lower contact 5 central shaft 1 lower end, axially evenly has 3 guiding gutters 6 on the central shaft 1 between upper connection 4 and the lower contact 5,6 guide functions of guiding gutter.Valve seat 2 is connected on the central shaft 1 of lower contact 5 upper ends, slidely connects 5 unsteady valve covers 3 on the central shaft 1 of valve seat 2 upper ends, forms valve by valve seat 2 and unsteady valve cover 3, closes when up, opens when descending.
Working procedure:
This oil pump enhancing device is connected on first segment sucker rod 8 upper ends of oil well pump 7 upper ends, according to well depth, also can be in second section sucker rod 8 upper ends or the 3rd joint sucker rod 8 upper ends respectively connect 1.This oil pump enhancing device is independent of outside the oil well pump.This oil pump enhancing device and oil pump plunger piston synchronous operation, when sucker rod 8 is up, valve seat 2 cooperates with unsteady valve cover 3, close guiding gutter 6, form negative pressuren zone in the tubing string chamber between oil well pump 7 and the oil pump enhancing device, it is stifled to eliminate vapour lock, amplify space in the oil well pump, pump efficiency has finally reduced cost for oil production along with rising, has increased the oil recovery well benefit.When sucker rod 8 was descending, valve seat 2 separated with unsteady valve cover 3, and guiding gutter 6 is opened, the normal extraction of liquid measure.This oil pump enhancing device is applicable to all kinds of pumping unit oil wells of continuous liquid supply ability.
