Abstract
The invention relates to a split type design technology for a double-barreled hanger assembly in an oil field wellhead Christmas tree and belongs to the technical field of petroleum machine design and manufacturing. The double-barreled hanger assembly comprises an assembly body, double-barreled hangers, single-barreled hangers, a rectangular sealing ring, a press plate, jackscrews, an upper flange and bolt nuts. The double-barreled hanger assembly is characterized in that each double-barreled hanger is formed by two independent single-barred hangers. According to the split type design technology for the double-barreled hanger assembly, a traditional integral double-barreled hanger is designed into the split type double-barreled hangers, when oil pipes are washed, any oil pipe of the two oil pipes can be independently taken out to be washed according to needs, and the other oil pipe can continue to work; in this way, on one hand, it is ensured that the oil pipes are washed in time, and on the other hand, the oil extraction yield is not influenced. Compared with a traditional integral double-barreled hanger assembly, the split type double-barreled hanger assembly has the advantages of being reasonable in structure, high in mobility, convenient to use and capable of saving labor and time.
Description
Technical field
The present invention relates to the dual tubing hanger assembly split-type design technology in a kind of oil field shaft mouth production tree, belong 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 hanging oil pipe, and it can not only realize the function hanging OIH tubing string, also plays the annular space effect between sealing oil pipe and production string.Generally the total Chengdu of boll-weevil hanger is single tube, also can adopt two-tube, to increase the latus rectum of flow string when needs strengthen oil recovery amount.The total Chengdu of traditional dual tubing hanger is all-in-one-piece, in order to immediately clear up the greasy dirt dirt on flow string post jamb in oil recovery process, prevent blocking pipe, usually need cleaning tubing, and just must stop production once needs cleaning and pull down oil pipe by two oil pipes and all take out and could clean with special tool, particularly when only need cleaning wherein an oil pipe time, also two oil pipes all must be taken out, otherwise cleaning tubing work just cannot realize, inevitably have impact on oil recovery amount thus, and dismounting oil pipe and installation oil pipe all quite bother during cleaning tubing, take a lot of work, time-consuming.Therefore people wish that a kind of dual tubing hanger that can make up above-mentioned defect comes out.
Summary of the invention
The drawback displayed when cleaning tubing for current monolithic dual tubing hanger assembly, the present invention proposes a kind of dual tubing hanger assembly split-type design technology, to realize the object of cleaning tubing without the need to stopping production.
To achieve these goals, Bian of the present invention gets following technical scheme and implements: a kind of dual tubing hanger assembly split-type design technology, it comprises assembly body, dual tubing hanger, single tube hanger, rectangular seal, pressing plate, jackscrew, upper flange, bolt mother, described 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 characterized in that described dual tubing hanger is made up of two separate single tube hangers; Described upper flange is provided with two fixing single tube hangers and fuel-displaced stepped hole; Described rectangular seal, pressing plate are equipped with two holes of matching with single tube hanger external diameter.Traditional monolithic dual tubing hanger is designed to split type dual tubing hanger by the present invention, when cleaning tubing, any one of can take out separately as required in two oil pipes cleans, an other oil pipe can work on, such one side ensure that the instant cleaning of oil pipe, does not delay oil recovery amount again on the other hand.
Compared with traditional integral formula dual tubing hanger assembly, the present invention has rational in infrastructure, mobility strong, easy to use, saving of labor, timesaving advantage.
Accompanying drawing explanation
Fig. 1 is structural principle schematic diagram of the present invention.
In FIG: 1 assembly body, 2 jackscrews, 3 rectangular seals, 4 dual tubing hangers, 5 bolt mothers, 6 upper flanges, 7 single tube hangers, 8 pressing plates.
Detailed description of the invention
As shown in Figure 1, dual tubing hanger 4 is split type, be made up of two separate single tube hangers 7, it is by rectangular seal 3, pressing plate 8, jackscrew 2, upper flange 6, bolt mother 5, be fixed on the tube chamber top of assembly body 1 side by side, two oil pick-up tube are rotatably connected on the Internal Pipe Thread of two single tube hanger 7 lower ends.Rectangular seal 3, pressing plate 8 are equipped with two holes of matching with single tube hanger 7, for sealing constraint while two single tube hangers 7, and the constraint sealing of another single tube hanger 7 was not lost efficacy when taking out any single tube hanger 7; Upper flange 6 is provided with two and fixes two single tube hangers 7 and fuel-displaced stepped hole respectively and stagger and do not communicate.When needing to clean an oil pipe wherein, unload bolt mother 5, upper flange 6, to outward winding again the jackscrew 2 on both sides, take out pressing plate 8, rectangular seal 3, extract a single tube hanger 7 wherein out and unload pipe cleaning, an other single tube hanger 7 and rectangular seal 3, pressing plate 8 are reloaded original position together with oil pipe, cover upper flange 6 bolt mother 5 fastening, then precession jackscrew 2 makes it move downward compression rectangular seal 3 by the inclined-plane on pressing plate 8, and this single tube hanger 7 can be worked on.Such oil recovery and cleaning tubing just can be carried out simultaneously, achieve the object that cleaning tubing does not need to stop production.
