Technical field
The invention belongs to the equipment in the narrow tube down-hole injecting gas injection operation suspension arrangement, specifically, is a kind of hanger of minor-diameter pipe subsurface agent and gas pouring device.
Background technology
After narrow tube down-hole injecting gas injection apparatus for work is lowered to gas well to narrow tube, some are needed the well of long period injecting, need to use the narrow tube suspension arrangement.The elemental operation mode is: hanger hangs over well head to narrow tube weight, with fixture block narrow tube is securely fixed in well head, loads onto sealing, re-uses auxiliary the suspension with earth anchor narrow tube is anchored on the ground.Can pass through the narrow tube injecting at any time as required.
Hanger is the key equipment of injecting gas injection suspension arrangement under the continuous pipe well of minor diameter, narrow tube weight can be hung over well head, as required can be at any time by narrow tube chemical injection in well.The shortcoming that exists is at present: one, the weight that can not effectively bear the continuous pipe of whole minor diameters; Its two, the continuous seal of tube of minor diameter is undesirable in the effect of well head; Its three, obstructed when the injecting of shaft bottom by the continuous pipe of minor diameter.
Summary of the invention
The present invention is achieved in that and comprises body, fixture block, jackscrew, sealing, upper flange plate, gland, guiding, narrow tube, narrow tube passes lower channel on the body, the body center is gone up on the lower side two fixture blocks is installed, jackscrew chucking by the left and right sides, guiding and sealing are installed in body top, guiding is connected with upper flange plate, and sealing is connected with gland, and steel ring is enclosed within on the body.
Body is a five-way, is similar to the hollow cuboid, and top is the hollow disc shape, adopts the steel ring sealing; The bottom is hollow cylindrical, has external screw thread; About the cylinder boss of a symmetrical hollow is respectively arranged; There is the cylinder boss of a hollow in the dead ahead; Its top of hollow channel is the great circle cylindrical passageway up and down, and positive center portion on the lower side is conical, and the bottom is the small cylindrical passage.
Fixture block is divided into two by a hollow cone body and forms, and hollow bulb is cylindrical, and the surface is through specially treated, to increase friction factor.
Jackscrew is lip pencil, and the top is taper, and inclined to one side the place ahead, middle part is provided with O shape ring recess, and inclined to one side rear, middle part is provided with external screw thread, and jackscrew is connected with body, and end has step to be the roundlet column, which is provided with spanner side.
The front of guiding is the semicircle arcuation, and its cross section takes the shape of the letter U, and is welded on the upper flange plate, with steel ring seal body and upper flange plate.
Sealing is hollow cylindrical, and the outside is provided with external screw thread, and sealing is connected with upper flange plate, and sealed external is provided with O shape ring recess and upper flange plate sealing; Sealed inside is provided with the v shaped ring groove for v-ring is installed, and sealing is provided with internal thread and is connected with gland.
It is cylindric that sealing-plug is ladder, and its big step is provided with O shape ring recess, is placed in the passage in body dead ahead, tightens up with pressure cap.
The invention has the advantages that: single ram type perventer can be sealed the pressure of narrow tube under gas well mouth, gas emptying with tubing string on the gas well mouth. the downhole tool of the continuous pipe of minor diameter is equipped with one way valve, can prevent pouring in down a chimney of the interior object of well. and the fixture block of hanger and jackscrew can be suspended on well head reliably with the continuous pipe of minor diameter; Guiding and the annular space of the continuous pipe of the salable minor diameter of hermetic unit with the hanger inner chamber; Make the auxiliary suspension and the earth anchorage on continuous pipe of minor diameter and ground by guiding. easy and simple to handle accurate, performance guarantees reliably.
Description of drawings
Fig. 1 is a main TV structure schematic diagram of the present invention;
Fig. 2 be A-A of the present invention to sectional view;
The specific embodiment
As shown in Figure 1, comprise body 1, fixture block 2, jackscrew 3, steel ring 4, v-ring 5, sealing 6, upper flange plate 7, gland 8, guiding 9, narrow tube 10, narrow tube 10 passes lower channel on the body 1, body 1 center is gone up on the lower side two fixture blocks 2 is installed, by jackscrew 3 chucking of the left and right sides, guiding 9 and sealing 6 are installed in body 1 top, and guiding 9 is connected with upper flange plate 7, sealing 6 is connected with gland 8, and steel ring 4 is enclosed within on the body 1.
Jackscrew 3 is lip pencil, and the top is taper, and inclined to one side the place ahead, middle part is provided with O shape ring recess, is provided with external screw thread after the middle part is inclined to one side, and jackscrew 3 is connected with body 1, and end has step to be the roundlet column, which is provided with spanner side.
The front of guiding 9 is the semicircle arcuation, and its cross section takes the shape of the letter U, and is welded on the upper flange plate 7, with steel ring 4 seal body 1 and upper flange plate 7.
Sealing 6 is hollow cylindrical, and the outside is provided with external screw thread, and sealing 6 is connected with upper flange plate 7, seals that 6 outsides are provided with O shape ring recess and upper flange plate 7 seals; Seal 6 inside and be provided with the v shaped ring groove for v-ring 5 is installed, sealing 6 is provided with internal thread and is connected with gland 8.
As shown in Figure 2, it is cylindric that sealing-plug 11 is ladder, and its big step is provided with O shape ring recess, is placed in the passage in body 1 dead ahead, tightens up with pressure cap 12.
Concrete course of action is: finish in narrow tube 10 down-hole injecting gas injection device operations, after narrow tube 10 is lowered to predetermined well depth, starts single ram type perventer and seal the pressure of narrow tube 10 under gas well mouth, with the gas emptying of tubing string on the gas well mouth.The minor diameter downhole tool of pipe 10 continuously is equipped with one way valve, can prevent pouring in down a chimney of the interior object of well.Restart double ram type preventer and seal narrow tube 10, with jackscrew 3 minor diameter is managed 10 continuously with the fixture block 2 of hanger and be suspended on the well head hanger securely, then the equipment more than the wellhead assembly double ram type preventer is all unloaded.Load onto the guiding 9 and sealing 6 parts of hanger, the sealing minor diameter is the annular space of pipe 10 and hanger inner chamber continuously, and is last, with minor diameter pipe 10 and ground earth anchorage continuously.
