Description
Technical field:
The utility model relates to a kind of petroleum machinery technical field, the hemispheric eddy flow rotary plunger oil-well pump that particularly a kind of pumping well is used.
Background technique:
At present, the beam hanger oil well pump that uses both at home and abroad all adopts the sucker rod pump and the tubing pump of American API standard manufacture.Be characterized in: plunger is made reciprocal straight line motion pumping crude oil in pump barrel under the pulling of sucker rod and pumping unit.Therefore the matching gap of plunger and pump barrel will have certain requirement.Excesssive gap, though descending smooth, wastage increases, pump efficiency reduces; The gap is too small descending not smooth, and the pump school is higher.Yet, arrived the oil recovery middle and later periods, because geology and hole condition change many unfavorable situations have just appearred: 1, plunger and pump barrel eccentric wear, cause the gap to increase, pumping power reduces, pump efficiency is low, the production fluid amount is few, wastes energy, pumping unit is made idle work, has to stop well operations, changes pump; 2, sand scale condenses, and plunger is stuck in pump barrel, can't work and have to stop well operations, influences the ordinary production of pumping unit, increases operating cost; 3, the box cupling of sucker rod leaks tube wall mill, makes the oil well can't ordinary production, stops well operations, reduces output, has increased the well casing cost; 4, sand easily forms the sand post in the upper end of plunger, buries plunger, makes pumping unit spur plunger and stops well operations, has also influenced oil well yield.
The model utility content:
The technical problems to be solved in the utility model provides a kind of hemispheric eddy flow rotary plunger oil-well pump, and this oil well pump has been realized plunger rotation under fluid power promotes, and prevents that sand from entering pump barrel, improved pump efficiency.Overcome the sucker rod partial wear of existing oil well pump, pump barrel and plunger eccentric wear, sand scale condenses, and plunger is stuck in pump barrel, and sand easily forms the sand post in the upper end of plunger, buries the deficiency of plunger.
Technical solution adopted in the utility model is: a kind of hemispheric eddy flow rotary plunger oil-well pump, form by anti-collision equipment, rotor, last thruster, centring means, hemisphere traveling valve, plunger body, following thruster, pump barrel and energy storage type hemisphere standing valve; Anti-collision equipment is made up of anti-collision block and crash bar, and anti-collision block upper end links to each other with sucker rod, and the lower end is milled with claw, and the crash bar upper end is connected with anti-collision block, and the lower end is connected with rotor; Rotor is made up of rotary sleeve, running shaft and bearing, and Bearing Installation is on running shaft, and running shaft is in rotary sleeve inside; Last thruster and following thruster are cylindrical, are milled with several helixes above; Anti-collision equipment, rotor, last thruster, plunger body, following thruster are threaded in proper order, the hemisphere traveling valve is contained in the plunger body, on last thruster and the following thruster centring means is housed, pump barrel is threaded with energy storage type hemisphere standing valve, and energy storage spring is equipped with in the hemisphere upper end of energy storage type hemisphere standing valve.
The beneficial effects of the utility model are: the utility model is owing to adopted anti-collision equipment, rotor, last thruster, plunger body, the structure that following thruster is threaded in proper order, thereby the utility model can guarantee that the stoste in the pump chamber is in the eddy flow state all the time, prevent the cohesion of sand scale, increased interior sealing, improved pumping power greatly, increased pump efficiency, simultaneously because stoste is in rotation status all the time, the resistance of plunger just is decomposed into opens and the power of cut-off valve and promote the power of plunger rotation, alleviated the eccentric wear of rod collar so to a certain extent to tubing wall, thereby protected oil well, prolonged the working life of well casing; The utility model has been owing to adopted on last thruster and following thruster the structure of centring means has been housed, thereby makes the working surface of the working surface of plunger and pump barrel contactless forever, fundamentally eliminated the eccentric wear of pump barrel and plunger, prolonged the working life of pump; The utility model is because the structure that has adopted pump barrel to be threaded with energy storage type hemisphere standing valve, thereby can make valve when closing, stop the secondary spring of valve ball, eliminated trip loss, simultaneously owing to adopt the rotating seal mode, stopped the impact of valve ball to the ball seat sealing strip, prolong the working life of standing valve, also improved pump efficiency simultaneously.
Description of drawings:
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
As shown in drawings, a kind of hemispheric eddy flow rotary plunger oil-well pump is made up of anti-collision equipment 1, rotor 2, last thruster 3, centring means 4, hemisphere traveling valve 5, plunger body 6, following thruster 7, pump barrel 8 and energy storage type hemisphere standing valve 9; Anti-collision equipment 1 is made up of anti-collision block and crash bar, anti-collision block upper end links to each other with sucker rod, the lower end is milled with three uniform claws, when bumping pump, three claws bump against on the interior step of box cupling, play spacing effect, and guard column cock body 6 is without prejudice, the crash bar upper end is connected with anti-collision block, and the lower end is connected with rotor 2; Rotor 2 is made up of rotary sleeve, running shaft and bearing, and two Bearing Installation are on running shaft, and running shaft is in rotary sleeve inside; Last thruster 3 and following thruster 7 are cylindrical, be milled with several helixes above, when the oil well pump proper functioning, by stoste flowing in spiral chute thruster is produced certain thrust, thereby plunger body 6 is at the uniform velocity rotated, the moment of thrust of thruster makes plunger body 6 rotate along the direction that screws of connecting thread, thereby has stopped the drawback that roofbolt is threaded off; Anti-collision equipment 1, rotor 2, last thruster 3, plunger body 6, following thruster 7 orders are threaded, hemisphere traveling valve 5 is contained in the plunger body 6, on last thruster 3 and the following thruster 7 centring means 4 is housed, pump barrel 8 is threaded with energy storage type hemisphere standing valve 9, and energy storage spring is equipped with in the hemisphere upper end of energy storage type hemisphere standing valve 9.
When plunger body 6 was up, energy storage type hemisphere standing valve 9 was opened, the energy storage spring compression on the energy storage type hemisphere standing valve 9.The rotary fluid that stoste in the pump barrel 8 is impacted on the rotor 2 makes its rotation descending, stirs stoste and becomes the motion of eddy flow shape.Simultaneously, stoste in 3 pairs of pump chambers of the last thruster of plunger body 6 upper ends produces impulsive torque makes plunger body 6 begin to rotate, guarantee that plunger body 6 is in the state of rotatablely moving all the time in pump barrel 8, sand scale in the stoste just is difficult to condense like this, in the pump barrel 8 and the stoste in the tubing string all be in the turn state, avoided the deposition of sand scale.
When plunger body 6 is descending, energy storage type hemisphere standing valve 9 is rapid rotary closing under the effect of spring, stopped the secondary spring of conventional valve ball when closing, reduced trip loss, the bump injury that whole ball sealing causes has been stopped in distinctive hemispheric rotary seal simultaneously.Meanwhile, the following thruster 7 of stoste impact pole cock body 6 lower ends in the pump barrel 8 drives plunger body 6 rotations.When stoste rotation is up to the plunger outlet valve, last thruster 3 begins to rotate, and has guaranteed that plunger body 6 at the uniform velocity rotation in whole descending process is descending.
The blue formula centring means 4 of spending at two ends has ensured that the working surface of plunger body 6 and the working surface of pump barrel 8 contact never, has stopped the scratch of contact.
