Description
Technical field
The utility model relates to oil field oil, well operation aid technology, particularly is that a kind of well head hanger is set upright instrument.
Background technology
At present, in oil field oil, well operation well workover process, cause the well head oil casing annular space poorly sealed after the hanger sealing ring damages, cause well head blowout out of control, or cause drive a well after the completion unsuccessful; In the construction, because wellhead blowout preventor must be installed, more increased the difficulty of seat hanger at the scene, caused the damage of sealing ring often, spoilage reaches 35%.Prior art can not address the above problem.
Summary of the invention
The purpose of this utility model is at above-mentioned technical problem, designs a kind of well head hanger and sets upright instrument, thereby avoided the problem that the seat hanger causes red copper sealing ring and fluorine glue sealing ring to damage in oil, the well operation well workover process.
The technical solution of the utility model comprises: long handle, connecting ring, short handle, retainer ring, swivel hook, pad, connecting bolt, steady pin; It is the pincerlike structure of hinge type that its well head hanger is set upright instrument, and the long handle right-hand member is provided with swivel hook, and the centre is provided with semicircular ring, and middle part, a left side is provided with connecting ring; The short handle right-hand member is provided with swivel hook, and the centre is provided with semicircular ring, is provided with retainer ring on the direction perpendicular to the semicircular ring diameter, and left end is provided with connecting ring; The upper end of three steady pins is inserted connecting ring, retainer ring, swivel hook respectively, is lined with pad, and the upper end snail pit that is screwed in steady pin by connecting bolt is fixedly connected, and two semicircular ring are formed the oil pipe through hole, so that tubing string is passed through.
Well head hanger according to the such scheme manufacturing is set upright instrument, and is simple in structure, easy to operate, avoided seat hanger in oil, the well operation well workover process to cause the infringement of red copper sealing ring and fluorine glue sealing ring, improves the well in operation success rate, avoids gas blowout accident to take place.

The specific embodiment
Below in conjunction with accompanying drawing enforcement of the present utility model is further elaborated:
This well head hanger is set upright instrument, comprising: long handle 1, connecting ring 2, short handle 3, retainer ring 4, swivel hook 6, pad 7, connecting bolt 8, steady pin 9; It is the pincerlike structure of hinge type that its well head hanger is set upright instrument, and long handle 1 right-hand member is provided with swivel hook 6, and the centre is provided with semicircular ring, and middle part, a left side is provided with connecting ring 2; Short handle 3 right-hand members are provided with swivel hook 6, and the centre is provided with semicircular ring, are provided with retainer ring 4 on the direction perpendicular to the semicircular ring diameter, and left end is provided with connecting ring 2; The upper end of three steady pins 9 is inserted connecting ring 2, retainer ring 4, swivel hook 6 respectively, is lined with pad 7, and the upper end snail pit that is screwed in steady pin 9 by connecting bolt 8 is fixedly connected, and two semicircular ring are formed oil pipe through hole 5.
Method of operating: at first, in the lower end of steady pin 9 inserted well head big four 14 (or preventer) respectively and the well head hanger is set upright the corresponding screw vent of instrument; Secondly; the upper end of three steady pins 9 is inserted connecting ring 2 respectively; retainer ring 4; swivel hook 6; shell tool 7; connecting bolt 8 is connected with the upper end of steady pin 9; two semicircular ring are positioned at tubing string 10 center of well head big four 14 (or preventer); thereby make hanger and well head big four 14 (or preventer) keep concentric circles; thereby play the effect that a hanger protection red copper sealing ring and fluorine glue sealing ring are not damaged; the 3rd; when well head hanger 15 stops during near well head; the well head hanger is set upright instrument 13 removes, slowly 15 of well head hangers on well head big four 14 (or preventer).
