Abstract
The utility model relates to a blowout wrecking device for mechanically installing a plug valve. The technical scheme is that the blowout wrecking device is movably connected on one side of a well mouth or a well repairing blowout preventer flange and mainly composed of a support rod sleeve, a fastening handle, a support spring, a movable support rod, a cross hand wheel, a cross guiding sleeve, a rotating handle, a rotating short section, a central support and the plug valve. The upper end of the support rod sleeve is connected with the movable support rod through the support spring and the fastening handle, the cross guiding sleeve is fixed at the top of the movable support rod, the cross hand wheel is arranged at one end of the cross guiding sleeve, the central support is connected at the other end of the cross guiding sleeve, the rotating short section and the rotating handle are arranged at the top of the central support, and the plug valve is movably connected at the bottom of the central support. The blowout wrecking device has the advantages that during workover treatment of an oil field, when the pressure in a well rises suddenly and blowout occurs, the plug valve can be installed fast, forcefully and mechanically, liquid gas in the well can be prevented from ejecting outwards through an oil pipe, and the problem that the plug valve cannot be installed easily without any supporting reference substance during traditional manual removing is solved.
Description
Technical field
The utility model relates to a kind of oil well repairing operation device, particularly a kind of mechanical erection plug valve blowout control device.
Background technology
At present, no matter in oil field overhaul or light maintenance operation team, all be furnished with the running string plug valve, during use, traditional mode of operation generally all is with the mode of upward detaining manually it to be installed in the top of running string; This traditional mode of operation, in the situation that blowout does not occur in Oil/gas Well, it is than more smoothly that traditional plug valve is installed, but, when Oil/gas Well really blowout occurs, when robbing the dress plug valve with this artificial mode again, following situation can occur: the one, if blowout pressure is little, the constructing operation personnel not great strength of membership dues just can rob and load onto plug valve, but cause potential harm can for the well head operating personnel; The 2nd, in the situation that blowout pressure increases gradually, because well head pressure is larger, the well head operating personnel are just difficult to be robbed plug valve on the tubing string that is contained in well head with traditional manual mode, even load onto strength and the long time that also can cost a lot of money.
Sign in above situation, for the in time generation of Prevention of blowout accident, the device of Fast Installation Prevention of blowout occurs to have behind the gas blowout accident with the well site, on-the-spot need a kind of can be safe, simple, convenient and rapid, installation, the reliable blowout control device of flexible adjustment, solve the on-the-spot problem that exists.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provide a kind of be specifically designed to rob be sprayed in the well workover trip-out process when blowout occurs, the mechanical erection plug valve blowout control device of plug valve is installed by force.
Its technical scheme is: the side at well head or well-repairing blowout preventor flange is flexibly connected blowout control device, described blowout control device is mainly by the support bar cover, fastening handle, support spring, movable branching rod, horizontal handwheel, horizontal fairlead, rotary handle, rotating short-knot, center bearing bracket, plug valve forms, support spring is passed through in the upper end of described support bar cover, fastening handle connects movable branching rod, horizontal fairlead is fixed at the top of movable branching rod, one end of horizontal fairlead is provided with horizontal handwheel, the other end connects center bearing bracket, the top of center bearing bracket is provided with rotating short-knot, rotary handle, the bottom is flexibly connected plug valve.
Above-mentioned blowout control device is connected to a side of well head or well-repairing blowout preventor flange by base for supporting, U-shaped groove, fixed pin shaft, active pin shaft, described base for supporting is fixed on a side of well head or well-repairing blowout preventor flange, and base for supporting is provided with U-shaped groove.
Operating principle of the present utility model is: base for supporting is passed through set bolt, nut is fixed on two corresponding on 250 well heads or well-repairing blowout preventor flange bolts hole, behind set bolt and nut screwing clamping, plug valve has been installed on the rotating short-knot in advance, then by the center of rotation support and regulate horizontal handwheel centering tubing coupling center, then being rotated counterclockwise vertical release handle drops on plug valve in the tubing coupling in the button, clockwise rotate again rotating short-knot, so just plug valve tightly can be tightened in the tubing coupling, last cut-out tap valve can be finished and rob spray.
The beneficial effects of the utility model are: mainly adopt first support to be installed on wellhead flange, then use on the handwheel of blowout control device itself and detain, be used for the oil well repairing operation process, if borehole pressure raises suddenly, when blowout occurs, can be fast the blowout control device of mechanical erection plug valve by force, to prevent that liquid gas sprays by the oil pipe inner chamber in the well outward, solved and unloaded plug valve on the Traditional Man without the problem that supports object of reference and be not easy to install.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model;
Among the upper figure: base for supporting 1, U-shaped groove 2, fixed pin shaft 3, active pin shaft 4, support bar cover 5, fastening handle 6, support spring 7, movable branching rod 8, horizontal handwheel 9, horizontal fairlead 10, set bolt 11, rotary handle 12, rotating short-knot 13, center bearing bracket 14, spacer pin 15, plug valve 16; Box cupling A, tubing string elevator B, well head big four C.
The specific embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
Side at well head or well-repairing blowout preventor flange is flexibly connected blowout control device, described blowout control device is mainly by support bar cover 5, fastening handle 6, support spring 7, movable branching rod 8, horizontal handwheel 9, horizontal fairlead 10, rotary handle 12, rotating short-knot 13, center bearing bracket 14, plug valve 16 forms, the upper end of described support bar cover 5 is by support spring 7, fastening handle 6 connects movable branching rod 8, horizontal fairlead 10 is fixed at the top of movable branching rod 8, one end of horizontal fairlead 10 is provided with horizontal handwheel 9, and fixing by set bolt 11, the other end connects center bearing bracket 14 by spacer pin 15, the top of center bearing bracket 14 is provided with rotating short-knot 13, rotary handle 12, the bottom is flexibly connected plug valve 16.
