Description
Technical field
The present invention is the equipment of using during boll-weevil hanger under the oil field operation, specifically boll-weevil hanger erection device.
Background technology
Will be lowered to hanger during the oil field oil water well operations and the OIH pipe is suspended on the big four of wellhead assembly, hanger also will play the Seal Oil sleeve pipe, and the above highly pressurised liquid of hanger can not be leaked in the sleeve pipe, therefore, sealing ring is arranged on the hanger.Hanger will pass through preventer in being lowered to process, because derrick tilts to cause hanger honestly not to be lowered to, the problem that the flashboard in the preventer is hung the sealing ring on the bad hanger often occurs.Hung bad problem in order to solve hanger sealing ring in being lowered to process, to promote to be connected to oil pipe on the hanger with manpower from the deflection a party at the scene, but Manual-pushing is not only wasted time and energy, the uncertain hanger that can make is placed in the middle, and the operator will be near the well head observation of bowing, can not hide burst accident, have potential safety hazard.
Summary of the invention
The objective of the invention is to design a kind of boll-weevil hanger erection device, make it when hanger is lowered to through preventer, can not hang bad sealing ring, and easy, safety, time saving and energy saving.
The object of the present invention is achieved like this: comprise the lifting oil pipe, sealing ring, hanger, preventer, connecting bolt, sealing ring is installed on the hanger, promoting the oil pipe bottom is connected with hanger, connecting well inner oil tube under the hanger, also comprise roller, wheel carrier, support, base, support bar, adjusting screw(rod), supporting seat, base is fixed on the preventer by connecting bolt, rail groove is arranged on the base, the right flank of base has screw, the internal thread of this screw and the external screw thread of adjusting screw(rod) are supporting, adjusting screw(rod) passes in the rear injection groove from the right flank screw of base, supporting seat is sleeved on the left end of adjusting screw(rod), supporting seat in rail groove, the lower end of support bar and supporting seat hinge connection, the bottom hinge connection of the upper end of support bar and support, the lower end of support and base hinge connection, wheel carrier is installed in the top of support, and roller is installed on the wheel carrier, and roller is near the outside that promotes oil pipe.
Roller surface is provided with the circular arc groove, and the radius of circular arc groove is identical with the radius that promotes oil pipe.
The right flank screw screw thread of adjusting screw(rod) external screw thread and base is rectangular thread, and pitch is 4-6mm.
The invention has the beneficial effects as follows: the rotation adjusting screw(rod), can promote to promote oil pipe makes it be in the bosom position of preventer, when being lowered to by preventer, hanger can not contact with the flashboard in the preventer, sealing ring on the hanger can not hung bad, guarantee to construct successfully, avoid operation to do over again, the rotation adjusting screw(rod) is energy righting hanger just, easy, quick, time saving and energy saving, security incident need not near well head, can not occur in operating personnel, therefore, the new shape of this practicality has significant economic benefit and social benefit.
Description of drawings
