Abstract
The utility model discloses an oil well helps takes out ware improvement structure, its body outside is equipped with the rubber sealing ring, separates through the spacer ring between each rubber sealing ring, and its focus lies in: the spacer ring is wrapped on the sealing rubber ring. The interval of the upper and lower spacing rings of the sealing rubber ring is smaller than the height and width of the sealing rubber ring. Through the structure that wraps the seal rubber ring with the spacer ring, the seal rubber ring is not easy to damage, break and fall off. Therefore, the sealing rubber ring is only normally worn, so that the service life is prolonged, the well repairing cost is reduced, the cost is saved, and the long-acting production of an oil well is ensured.
Description
Technical field
The utility model relates to from the equipment of underground mining oil, particularly relates to a kind of structural improvement of oil well pumping-assistant device.
Background technology
Oil pumper in the producing well in conventional oil field has only deep well pump, and exhausting-aid device is a kind of picking device that helps that increases in the sucker rod of well head in the middle of the deep well pump in shaft bottom, it can arrive shaft bottom pump piston pressure is decomposed to well mouth of oil well, as: the head of liquid of 2000 meters fluid column middle-deep well pump is 2Pa.If add an exhausting-aid device that certain sealability is arranged in the centre, then the head of liquid of deep well pump can relatively reduce, and utilizes this principle just can improve the efficiency of pump of deep well pump, the head of liquid of minimizing deep well pump and the deep well pump wastage that causes because of sealing.That is to say that exhausting-aid device can play pump efficiency that increases deep well pump and the effect that increases output in the pit shaft of oil well.
The oil well pumping-assistant device of creation before the utility model creator, be that the patent No. is ZL94247199.7, it has top connection and body, top connection and body are connected as a single entity, and this top connection is a hollow, and inside is equipped with valve ball and valve seat, also has passage with external communications, body is a part hollow, and cavity has the passage with exterior, and the outside of body also has with pressure ring fixing V-seal ring and spacer ring.Its valve ball is closed when sucker rod is up, make oil up, when sucker rod is descending, after valve ball is opened, oil is entered always from following hole upwards flow, so just make exhausting-aid device in the process that pumps of sucker rod, reach the purpose of decomposition deep well pump fluidization tower pressure oil pumping, help upwards oil pumping of deep well pump with exhausting-aid device, can improve the efficiency of pump of deep well pump, have more oil, increase output.
Yet obscission in use takes place in the main accessory sealed rubber ring of above-mentioned technology easily, and for this reason, the utility model creator has carried out structural improvement on this basis.
The utility model content
The utility model is improved on the basis of original oil well pumping-assistant device, increases the slip-off preventing ability of O-ring seal, and cushion rubber easily falls, perishable problem thereby solve.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of oil well pumping-assistant device structure-improved, its body exterior is equipped with O-ring seal, separates by spacer ring between each O-ring seal, and it focuses on: this spacer ring is coated on the sealing cushion rubber.
Wherein: the interval of lower isolating ring is less than the height and the width of sealing cushion rubber on the sealing cushion rubber.
The V-shaped structure of described O-ring seal.
Described O-ring seal is trapezium structure.
Described spacer ring is ㄣ shape structure.
The diameter of described spacer ring is in the 60-61mm scope.
Because the utility model has adopted said structure, has more following beneficial effect:
By spacer ring being encased the structure of O-ring seal, can make the sealing cushion rubber not fragile, the fracture and come off.So O-ring seal has only normal wear, this has just prolonged application life, has reduced workover cost, has also saved cost, guarantees the long-acting production of oil well.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is the structural representation of the utility model oil well pumping-assistant device, and wherein part is analysed and observe.
The specific embodiment
As shown in Figure 1, be the structural representation of the utility model embodiment.It has top connection 1 and body 8, and top connection 1 is connected as a single entity with body 8, and top connection 1 is a hollow, cavity has passage 2 and exterior, body 8 is a part hollow, and cavity has passage 9 and exterior, and this passage 9 need be positioned at the below of outside seal ring.O-ring seal 6 is equipped with in the outside of body 8, separate by spacer ring 7 between each O-ring seal 6, O-ring seal 6 and spacer ring 7 are pushed down by the hold-down ring 5 on the threaded screw thread that is connected body 8 and are fixed on outside the body 8, spacer ring 7 is structure as shown in the figure, it is ㄣ shape, and the bottom and the sidepiece of sealing cushion rubber 6 encased.The interval of lower isolating ring is less than the height and the width of sealing cushion rubber on the sealing cushion rubber.Have valve seat 4 and valve ball 3 in top connection 1 inside, it plays one way valve.The outside of this exhausting-aid device can directly contact with the internal diameter of oil pipe, and special-purpose pump barrel also can be arranged.
The quantity of sealing cushion rubber 6 can be decided according to the required degree of depth in well of exhausting-aid device, and then used quantity was some more when the degree of depth was big, and the material of O-ring seal 6 is oil resistant temperature resistant rubber or Polyurethane, and the external diameter of its end should be greater than oil pipe or pump barrel internal diameter 2-4mm.
The sealing cushion rubber can V-shaped or trapezium structure.Wherein, the diameter of this spacer ring is within the 60-61mm scope.
In sum, the utility model from application target, on the usefulness, viewpoint such as progressive and novelty sets forth, the practical improvement that it has, function enhancement and practical important document that novel Patent Law is emphasized have been met, shown in the implementation and accompanying drawing that the utility model is above, be one of the utility model preferred embodiment, be not to limit to the utility model with this, be with, such as with approximate, identical person such as structure of the present utility model, device, feature, all should belong to of the present utility model founding within purpose and the claim.
