Abstract
The utility model relates to a hanging water power-type soft sealing rod-type pump which is used for an oil pumping machine well in an oil field, composed of a hanger outer cylinder (1), a hanger central pipe (3), an upper and a lower bearing rings (4), (7), an asbestos sealing part (5), a metal ring (6), an oil pumping rod (8), a short joint (9) of an oil pipe, a plunger joint (10), a tail pipe (11), a pump body (13), and a sand-prevention pipe (15). When the utility model works, a deep-well pump and a central pipe seat of a hanging sealing device are arranged on a table shoulder of the hanger outer cylinder. The pump has the advantages of the existing pipe pump and a rod pump. When the pump is used, the trouble that the oil pipe is dismounted when a well is repaired and the pump is detected can be avoided, and the operation workload and the labor strength can be decreased; in addition, the oil drainage can be carried out under the condition that an oil drainage device is not mounted.
Description
The utility model relates to a kind of mechanical oil recovery device that is used for oil field pumping well: hang waterpower formula soft seal sucker rod pump.
At present, the bar oil extraction pump that has of Oilfield using mainly contains two kinds of tubing pump and sucker rod pumps.Tubing pump directly is connected on the tubing string lower end, though simple in structure, the pump footpath is big, the OIH pipe all must be tripped out when changing pump.Need not play oil pipe when the major advantage of sucker rod pump is well repairing and pump checking, shortcoming is because of being cone Metal Contact sealing can to cause leakage inadequately if any foreign material or machining accuracy on its structure, and the pump footpath is less.
The purpose of this utility model is to provide a kind of suspension waterpower formula soft seal sucker rod pump, and the improved sucker rod pump of this kind possesses the advantage of existing tubing pump, sucker rod pump, overcomes shortcoming separately, utilizes it can obtain exploitation effect and economic benefit preferably.
The utility model is to realize like this.It is made up of hanger urceolus 1, center tube joint 2, hanger center tube 3, upper and lower load-bearing ring 4,7, asbestos seal spare 5, metal ring 6, sucker rod 8, tubing nipple 9, plunger connector 10, tail pipe 11, pump housing upper connection 12, the pump housing 13, box cupling 14, anti-sandpipe 15 and plug 16, wherein, hanger urceolus 1, center tube joint 2, hanger center tube 3, go up load-bearing ring 4, Sealing 5, metal ring 6, load-bearing ring 7 constitutes and hangs the sealer parts down, all the other component constitute deep-well pumps.This sucker rod pump general structure is as follows with the assembling feature: hanger urceolus 1 upper end is connected with tubing string by screw thread, and the lower end is connected with tail pipe 11, box cupling 14, anti-sandpipe 15 and plug 16 in turn by screw thread; Hanger center tube 3 upper ends link to each other with center tube joint 2 with screw thread, and the lower end is connected with tubing nipple 9, pump housing upper connection 12 and the pump housing 13 in turn by screw thread; Annular space between hanger urceolus 1 and the hanger center tube 3 is equipped with seal section, and sealing section upper and lower end is respectively upper and lower load-bearing ring 4,7, is arranged at intervals with many group asbestos seal spares 5 and metal ring 6 therebetween; Center tube joint 2 places load-bearing ring 4 tops, by with the hanger center tube 3 that is threaded the pump housing 13 being suspended on the tubing string bottom with it, 8 of sucker rods in the tubing string pass through plunger connector 10 and are connected with the plunger of its below, realize the suspension of sucker rod and deep-well pump by the shoulder between hanger center tube 3 and the plunger connector 10.During use, the suspension sealer urceolus of this pump is connected in oil pipe master afterbody with in the oil pipe lower going-into-well, then deep-well pump, plunger, the center tube of band soft seal, sucker rod are connected together, by rod string deep-well pump, suspension sealer center base are placed on the outer shoulder of hanger, utilize oil, sleeve pipe head of liquid difference that pump is fixed on the hanger urceolus shoulder, realize the sealing of urceolus and center tube simultaneously.
The utility model is as having bar deep-well pump pump footpath only than the little one-level of tubing pump, and working principle is identical with tubing pump, has only changed sealing means and just tubing pump has been transform as sucker rod pump.Adopt this kind pump can avoid tubing pump when well repairing and pump checking, to remove the trouble of oil pipe, reduce work operations amount and labor intensity, and be suitable for and apply not descend to get final product under the situation of oil drainer draining.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing enforcement of the present utility model is imposed explanation.
In the utility model, hanger urceolus (1) is the bigger cylindrical body of a upper/lower terminal diameter, and inner headed face has between the upper/lower terminal of female thread and middle cylinder and is respectively conical surface transition, the up big and down small reducing in circle bottom in the middle cylinder; Form a shoulder.Center tube joint (2) is one to have the short tube of female thread.Hanger center tube (3) is the bigger pipe of a bottom diameter, and its upper end has the external screw thread that matches with center tube joint (2), and there is female thread the lower end, and a shoulder is arranged between the upper and lower part.Last load-bearing ring (4) upper end is a plane, and the lower end is the conical surface of slope inwardly (outer thick interior thin); Following load-bearing ring (7) then in contrast, the lower end is the plane, the upper end is the intilted conical surface.Metal ring (6) upper and lower end is the intilted conical surface.Asbestos seal spare (5) then goes to upper and lower two ends and is the circular of outward-dipping (interior thick outer thin) conical surface.Each parts of deep-well pump part and common deep-well pump are roughly the same.
