Abstract
The utility model discloses telescopic fully-closed well head equipment. The telescopic fully-closed well head equipment comprises a connecting chuck connected with a pumping unit polish rod, and an upper connector connected with the connecting chuck, wherein a sealing element is arranged at the joint of the connecting chuck of the upper connector, the upper connector is connected with telescopic sleeves through bolts, the upper parts of the telescopic sleeves are provided with spring collars for limiting, one end of the telescopic sleeve at the lowermost part is fixedly connected with a bottom board, and the bottom board is further provided with a connecting threaded head connected with a well head. According to the equipment, the structure of the well head is simplified, the pollution caused by oil leakage is reduced, the power consumed by friction is reduced, the labor intensity of workers is reduced, the service life of the polish rod is prolonged, and the installation and maintenance costs are reduced; connection without relative movement between the polish rod and an oil well is realized, so that the well head is positioned in a static seal state, and the effect of no leakage is achieved.
Description
Technical field
The utility model relates to a kind of oil pumping in oil fields well head device, is specifically related to a kind of telescopic hermetically sealed wellhead assembly.
Background technology
Beam pumping unit is a large amount of a kind of pumping units that use of current middle stripper well in the world.It is to utilize oil pumper to drive the reciprocating motion of the pistons that in tubing string, sucker rod connects, and pump barrel and shaft bottom crude oil are lifted to ground.Owing between sucker rod and oil pipe, having relative motion, so on the well head of this kind equipment, all be furnished with packing box, prevent the crude oil leakage.The use of packing box, increased the load of oil pumper, improved the oil extraction cost, and draining has polluted environment, simultaneously owing to often changing the labour intensity that packing has increased the workman.On the other hand, the basis that trueness error during due to erection equipment and oil pumper long-term work cause changes, and has increased greatly the malalignment between sucker rod and oil pipe, makes packing place eccentric wear serious, cause the wearing and tearing of polished rod and oil pick-up tube, form the serious equipment breakdowns such as disconnected bar.So from fundamental significance, it is very urgent and necessary developing a kind of brand-new hermetically sealed Novel wellhead of nothing leakage.
Summary of the invention
In order to solve the deficiencies in the prior art, the utility model discloses a kind of telescopic hermetically sealed wellhead assembly.
The technical solution of the utility model is: comprise the connection dop be connected with oil-extractor polish-rod, with the described upper binding head that is connected the dop connection, the junction of described connection dop and upper binding head also is equipped with seal, described upper binding head has been bolted telescopic tube, the top of telescopic tube is provided with spring collar and carries out spacing, one end of described foot telescopic tube is fixedly connected with base plate, on described base plate, also is provided with the connecting filament head be connected with well head.
Further improvement of the utility model comprises:
Described connecting filament head also is provided with supporting positive cover.
Between described two adjacent sleeves, connect by elastic component, described elastic component is the outward flange structure.
On described sleeve, also be provided with limiting section, be fixed with cushion pad on described limiting section.
Described elastic body is polyurethane elastomer or Jia Bujia steel wire elastic caoutchouc.
The utility model has been simplified shaft collar, has reduced the draining pollution, has reduced the friction consumed power, reduces labor strength, improves polished rod application life, reduces the installation and maintenance cost.By the connection of hermetically sealed telescopic tube, realize between polished rod and oil well without being connected of relative motion, make well head all be in the static seal state, realize truly without revealing.Overcome the existing all drawbacks that seal by packing box, as leakage, eccentric wear, useless friction work, the replacing of increase, bother etc.Thereby play the purpose of environmental protection and energy saving.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, connect dop, 2, seal, 3, upper binding head, 4, telescopic tube, 5, cushion pad, 6, elastic component, 7, supporting positive cover, 8, base plate, 9, the connecting filament head, 10, spring collar.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
As shown in Figure 1, a kind of telescopic hermetically sealed wellhead assembly of the utility model, comprise the connection dop 1 be connected with oil-extractor polish-rod, with the described upper binding head 3 that is connected dop 1 connection, the junction of described connection dop 1 and upper binding head 3 also is equipped with seal 2, described upper binding head 3 has been bolted telescopic tube 4, the top of telescopic tube 4 is provided with spring collar 10 and carries out spacing, one end of described telescopic tube 4 is fixedly connected with base plate 8, on described base plate 8, also is provided with the connecting filament head 9 be connected with well head.Described connecting filament head 9 also is provided with supporting positive cover 7.
Between described two adjacent sleeves, connect by elastic component 6, described elastic component 6 is the outward flange structure.On described sleeve, also be provided with limiting section, on described limiting section, be fixed with cushion pad 5.Described elastic body is polyurethane elastomer or Jia Bujia steel wire elastic caoutchouc.
The utility model has been simplified shaft collar, has reduced the draining pollution, has reduced the friction consumed power, reduces labor strength, improves polished rod application life, reduces the installation and maintenance cost.By the connection of hermetically sealed telescopic tube, realize between polished rod and oil well without being connected of relative motion, make well head all be in the static seal state, realize truly without revealing.Overcome the existing all drawbacks that seal by packing box, as leakage, eccentric wear, useless friction work, the replacing of increase, bother etc.Thereby play the purpose of environmental protection and energy saving.
Above demonstration and described basic principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and manual, describes just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
