Abstract
The present invention relates to a kind of split type dual tubing hanger assembly, belong to Petroleum Machinery Design manufacturing technology field.It is female that it includes assembly body, dual tubing hanger, single tube hanger, rectangular seal, pressing plate, jackscrew, upper flange, bolt, it is characterized in that the dual tubing hanger is made up of two separate single tube hangers, traditional monoblock type dual tubing hanger is designed as split type dual tubing hanger by the present invention, in cleaning tubing, can individually take out as needed in two oil pipes any one is cleaned, an other oil pipe can work on, the instant cleaning of oil pipe is so on the one hand ensure that, does not on the other hand delay oil recovery amount again.Compared with traditional monoblock type dual tubing hanger assembly, the present invention have rational in infrastructure, mobility strong, easy to use, saving of labor, it is time saving the advantages of.
Description
Technical field
The present invention relates to a kind of split type dual tubing hanger assembly, the dual tubing hanger assembly split-type design technology particularly in oil field shaft mouth production tree, belongs to Petroleum Machinery Design manufacturing technology field.
Background technology
In the production tree of oil field shaft mouth, boll-weevil hanger assembly is a kind of necessary devices for hanging oil pipe, and it can not only realize the function of suspension OIH tubing string, and the annular space also acted as between sealing oil pipe and production string acts on.Generally the total Chengdu of boll-weevil hanger is single tube, when need increase oil recovery amount when also can use it is two-tube, to increase the latus rectum of flow string.The total Chengdu of traditional dual tubing hanger is monoblock type, in order to clear up the oil foulant on flow string post jamb immediately in oil recovery process, prevent from blocking pipeline, usually need cleaning tubing, and it must just be stopped production when cleaning is needed and pull down oil pipe two oil pipes are all taken out and could be cleaned with specific purpose tool, particularly when only needing to clean a wherein oil pipe, also two oil pipes must all be taken out, otherwise cleaning tubing work can not just be realized, thus it inevitably have impact on oil recovery amount, and dismounting oil pipe and installation oil pipe are all fairly cumbersome during cleaning tubing, take a lot of work, it is time-consuming.Therefore it is desirable to have a kind of dual tubing hanger appearance that can make up drawbacks described above.
The content of the invention
The drawbacks of being displayed for current monoblock type dual tubing hanger assembly in cleaning tubing, the present invention propose a kind of split type dual tubing hanger assembly, and dual tubing hanger assembly split-type design technology can realize purpose of the cleaning tubing without stopping production.
To achieve these goals, the present invention takes following technical scheme to implement：A kind of dual tubing hanger assembly split-type design technology, it is female that it includes assembly body, dual tubing hanger, single tube hanger, rectangular seal, pressing plate, jackscrew, upper flange, bolt, the dual tubing hanger is fixed on the tube chamber top of assembly body by rectangular seal, pressing plate, jackscrew, upper flange, bolt mother, it is characterised in that the dual tubing hanger is made up of two separate single tube hangers；The upper flange is provided with two fixed single tube hangers and fuel-displaced stepped hole；Two holes being engaged with single tube hanger external diameter are equipped with the rectangular seal, pressing plate.Traditional monoblock type dual tubing hanger is designed as split type dual tubing hanger by the present invention, in cleaning tubing, can individually take out as needed in two oil pipes any one is cleaned, an other oil pipe can work on, the instant cleaning of oil pipe is so on the one hand ensure that, does not on the other hand delay oil recovery amount again.
Compared with traditional monoblock type dual tubing hanger assembly, the present invention have rational in infrastructure, mobility strong, easy to use, saving of labor, it is time saving the advantages of.
Brief description of the drawings
Fig. 1 is the principle schematic diagram of the present invention.
In Fig. 1：1 assembly body, 2 jackscrews, 3 rectangular seals, 4 dual tubing hangers, 5 bolts mother, 6 upper flanges, 7 single tube hangers, 8 pressing plates.
Embodiment
As shown in Figure 1, dual tubing hanger 4 is split type, it is made up of two separate single tube hangers 7, it passes through rectangular seal 3, pressing plate 8, jackscrew 2, upper flange 6, bolt mother 5, the tube chamber top of assembly body 1 is fixed on side by side, and two oil pick-up tubes are rotatably connected on the Internal Pipe Thread of two lower ends of single tube hanger 7.Two holes being engaged with single tube hanger 7 are equipped with rectangular seal 3, pressing plate 8, constraint sealing while for two single tube hangers 7, and the constraint of another single tube hanger 7 is sealed and not failed when taking out any one single tube hanger 7；Upper flange 6 is fixed two single tube hangers 7 and fuel-displaced stepped hole and staggered and is not communicated with respectively provided with two.When needing to clean an oil pipe therein, unload bolt mother 5, upper flange 6, the jackscrew 2 on both sides is outwarded winding again, take out pressing plate 8, rectangular seal 3, extract a single tube hanger 7 therein out and unload pipe cleaning, an other single tube hanger 7 and rectangular seal 3, pressing plate 8 are reloaded into original position together with oil pipe, upper flange 6 is covered to be fastened with bolt mother 5, then precession jackscrew 2 makes it move downward compression rectangular seal 3 by the inclined-plane on pressing plate 8, this single tube hanger 7 is can continue to work.So recover the oil and cleaning tubing can be carried out simultaneously, realize the purpose that cleaning tubing need not stop production.
