Abstract
The utility model relates to a separate type double-barreled hanger assembly. The separate type double-barreled hanger assembly comprises an assembly body, a double-barreled hanger, single-barrel hangers, a rectangular sealing ring, a pressing plate, jackscrews, an upper flange and bolt nuts, wherein the double-barreled hanger is composed of two mutually independent single-tube hangers. According to the utility model, the traditional integrated double-barreled hanger is designed into the separate type double-barreled hanger; and when cleaning is performed on oil pipes, any one of the two oil pipes can be taken out separately for cleaning according to the need while the other oil pipe can continue working. Therefore, for one aspect, immediate cleaning of the oil pipes is not only guaranteed; but for the other aspect, oil extraction output is also not delayed. Compared with the traditional integrated double-barreled hanger assembly, the separate type double-barreled hanger assembly, disclosed by the utility model, has the advantages of being rational in structure, strong in maneuverability, convenient to use, labor-saving and time-saving.
Description
Technical field
The utility model relates to the dual tubing hanger assembly in a kind of oil field shaft mouth production tree, and the split-type structural that particularly this dual tubing hanger assembly is inner belongs to Petroleum Machinery Design manufacturing technology field.
Background technology
In the production tree of oil field shaft mouth, the boll-weevil hanger assembly is a kind of indispensable device that hangs oil pipe, and it not only can realize hanging the function of OIH tubing string, also plays the annular space effect between sealing oil pipe and production string.The total Chengdu of boll-weevil hanger is single tube generally speaking, when needs strengthen oil recovery amount, also can adopt two-tube, to increase the latus rectum of flow string.The total Chengdu of traditional dual tubing hanger is all-in-one-piece, in oil recovery process, for the greasy dirt dirt on the instant cleaning flow string post jamb, prevents blocking pipe; Usually need clean oil pipe; And in case just must stop production when need cleaning and pull down oil pipe two oil pipes are all taken out and could clean with special tool, particularly when need cleaning wherein during an oil pipe, also must two oil pipes all be taken out; Otherwise wash oil plumber does just can't realize; Influenced oil recovery amount thus inevitably, and when cleaning oil pipe the dismounting oil pipe with all suitable troubles of oil pipe are installed, take a lot of work, time-consuming.Therefore people hope to have a kind of dual tubing hanger that can remedy above-mentioned defective to come out.
Summary of the invention
To the drawback that present monolithic dual tubing hanger assembly is displayed when cleaning oil pipe, the utility model proposes a kind of split type dual tubing hanger assembly, to realize cleaning the purpose that oil pipe need not to stop production.
To achieve the above object, the present utility model posed to the following technical implementation of the program: one split twin tube suspension assembly, which includes the assembly of body, twin-tube hanger, single-tube hanger, rectangular seals, plate, top wire , the upper flange, bolts mother, said double tube hanger through a rectangular ring, plate, the top wire, the upper flange, bolts fixed to the base body lumen of the upper assembly, wherein the double-pipe hangers two independent single pipe hanger constituted; said upper flange is provided with two fixed single pipe hanger and the oil level hole; said rectangular ring, pressure plate has two suspension with single tube diameter hole is fitted.The utility model is designed to split type dual tubing hanger with traditional monolithic dual tubing hanger; When cleaning oil pipe; Any one that can take out separately as required in two oil pipes is cleaned; An other oil pipe can work on, and has guaranteed the instant cleaning of oil pipe so on the one hand, does not delay oil recovery amount on the other hand again.
Compare with traditional integral formula dual tubing hanger assembly, the utlity model has rational in infrastructure, mobility strong, easy to use, saving of labor, timesaving advantage.
Description of drawings
Fig. 1 is the structural principle sketch map of the utility model.
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.
The specific embodiment
As shown in Figure 1; Dual tubing hanger 4 is split type; Form by two separate single tube hangers 7; It is fixed in the tube chamber top of assembly body 1 side by side through rectangular seal 3, pressing plate 8, jackscrew 2, upper flange 6, bolt mother 5, and two oil pick-up tube are rotatably connected on the Internal Pipe Thread of two single tube hanger 7 lower ends.Be equipped with two holes of matching on rectangular seal 3, the pressing plate 8 with single tube hanger 7, constraint sealing when being used for to two single tube hangers 7, and the constraint of another single tube hanger 7 seals and did not lose efficacy when taking out any single tube hanger 7; Upper flange 6 is provided with two fixing respectively two single tube hangers 7 with fuel-displaced stepped hole and stagger and do not communicate.When needs clean oil pipe wherein; Unload bolt mother 5, upper flange 6; The jackscrew 2 on both sides of outwarding winding again takes out pressing plate 8, rectangular seal 3, extracts a single tube hanger 7 wherein out and unloads pipe and clean; An other single tube hanger 7 and rectangular seal 3, pressing plate 8 are reloaded original position together with oil pipe; It is fastening to cover upper flange 6 usefulness bolts female 5, and precession jackscrew 2 moves downward it through the inclined-plane on the pressing plate 8 and compresses rectangular seal 3 then, and this single tube hanger 7 can be worked on.Oil recovery and cleaning oil pipe just can carry out simultaneously like this, have realized cleaning the purpose that oil pipe need not stop production.
