Description
Technical field
The utility model relates to a kind of blowout control device.Be used in well recovery and well workover process, when causing the sleeve valve of wellhead assembly to damage, use this device can be with pressure can change four way valve by force owing to pressure reason or other reason no matter be.
Background technology
The oil well four-way is the foundation of wellhead assembly, and bilateral symmetry is installed two sleeve valves with control well inner oil tube and casing annulus, also is to carry out well-flushing kill-job, the central core of circulation of open flow in the well workover process.If four way valve damages, the annular space in the oil well is out of hand, changes four way valve having under the situation of pressure, and blowout will take place, and valve can be sprayed, and causes the personal safety accident.
Summary of the invention
The problem that the utility model solves is, at the problems referred to above, provides a kind of blowout control device of changing four way valve fast by force under a kind of situation that pressure arranged and can not cause bigger loss in well.
The utility model is that the technical scheme that the technical solution problem is adopted is:
A kind of blowout control device described in the utility model comprises the mount pad that is used to be installed on the wellhead flange, it is characterized in that: described mount pad is fixedly connected on the front end of guide pillar, the rear end of guide pillar and horizontal leading screw threaded engagement, the fixedly connected connecting rod in rear end of horizontal leading screw, this connecting rod rotatably is inserted on the guide seat, be installed with the lateral adjustments handle on this connecting rod, guide column sleeve is contained in the front end of sleeve, and the guide seat is fixedly mounted on the rear end of sleeve; The lower end of guide seat is fixedly connected with guide, and described guide is the cylinder of the threaded hollow of outer wall belt, and nut sleeve is sleeved on the outside of guide, and the inboard of nut sleeve has internal thread, nut sleeve and guide threaded engagement, the lower end jointing clip of nut sleeve.
The lower end of nut sleeve is connected with guide rod by snap ring, and guide rod is coaxial with nut sleeve, the fixedly connected clip in the lower end of guide rod.
Above-mentioned sleeve is provided with bolt hole, and caging bolt is installed in the bolt hole, and the correspondence position of guide pillar is provided with stopper slot.
About this blowout control device can be realized by screw thread, the moving of front and back, easy to use, can in well, have and change four way valve fast by force under the situation of pressure and can not cause bigger loss, avoid personnel are damaged.

The specific embodiment
A kind of blowout control device described in the utility model comprises the mount pad 11 that is used to be installed on the wellhead flange.As shown in Figure 2, the front end of mount pad 11 is the flat structure that has two bolts hole, and these two bolts hole can be used for being installed on the wellhead flange.As shown in Figure 1, mount pad 11 is fixedly connected on the front end of guide pillar 1, and guide pillar 1 is cylinder or pipe shape, at nut that has internal thread of the rear end of guide pillar 1 fixed installation, and by this nut and horizontal leading screw 4 threaded engagement.The fixedly connected connecting rod in rear end of horizontal leading screw 4, this connecting rod rotatably is inserted on the guide seat 5 by devices such as jump rings, is installed with lateral adjustments handle 10 on this connecting rod.Like this, rotation lateral adjustments handle 10 just can make 4 rotations of transverse wire thick stick, moves forward and backward thereby promote guide pillar 1.Guide pillar 1 is sleeved on the front end of sleeve 2, and guide seat 5 is fixedly mounted on the rear end of sleeve 2, and sleeve 2 plays the effect of guiding here, and guide pillar 1 can only be moved at the axis direction of sleeve 2; As shown in Figure 3, the lower end of guide seat 5 is fixedly connected with guide, and described guide is the cylinder of the threaded hollow of outer wall belt.Nut sleeve 7 is sleeved on the outside of guide, and the inboard of nut sleeve 7 has internal thread, nut sleeve 7 and guide threaded engagement, the lower end of nut sleeve 7 is connected with guide rod 12 by snap ring, and guide rod 12 is coaxial with nut sleeve 7, like this, guide rod 12 links together with nut sleeve 7, but can rotate relatively.The lower end of guide rod 12 is bolted to connection clip 8.
Certainly, for easy to use, vertical handgrip 9 can be installed on nut sleeve 7.
In addition, in order to limit the shift position of guide pillar 1, sleeve 2 is provided with bolt hole 3, in the bolt hole 3 caging bolt is installed, and the correspondence position of guide pillar 1 is provided with stopper slot.
The purpose of this utility model is achieved in that mount pad 11 is installed on two connection screws of wellhead flange by the well head bolt, and this two connection screw and well head four-way axis symmetry, makes this device parallel with four-way.The four way valve of changing is connected on the clip 8 with the clip skin, rotating vertical handgrip 9 adjustment clips 8 moves up and down corresponding with the well head four-way, rotate lateral adjustments handle 10, clip 8 is laterally moved, be connected with the clip skin, dismantle being connected of four way valve and well head with the well head four way valve, rotate lateral adjustments handle 10 horizontal outer moving then, make valve away from well head, valve is unloaded, finished the four way valve process that unloads.When robbing dress, earlier four way valve is installed on the clip 8, makes vertical and horizontal the moving of clip, make valve aim at four-way, under the effect of horizontal leading screw 4, install four way valve by vertical handgrip 9 and lateral adjustments handle 10.Dismantle being connected of valve and clip 8 then, this device is dismantled, move away from well head, promptly reached purpose.
