Abstract
The utility model relates to a jettison device for a blanking plug. A central tube 7 arranged on a lower crossbeam is connected with a self-sealing blowout prevention device 6 arranged on a middle crossbeam on a support frame 10 composed of an upper crossbeam, the middle crossbeam, the lower crossbeam and hydraulic cylinders, wherein the middle of three crossbeams is respectively provided with holes, and the hydraulic cylinders are arranged among the three crossbeams. A fixing slip 4 is arranged at the upper side of the support frame 10, and a hydraulic cylinder 2 can drive a traveling slip 3 by the upper crossbeam of the support frame 10. The utility model has the advantages of simple structure, convenient processing, reliable work and easy operation, and forcibly puts down a blanking plug to any prearranged position so as to ensure the normal operation of construction under the situation that an underground tubing string is plugged in the operation of no well killing and no spurting of an oil water well.
Description
The utility model relates to a kind of oilfield downhole operation instrument, especially for the blanking plug delivery device in the tubing string of oil-water well snubbing serving.
Before the utility model, each oil field carry out not kill-job of oil-water well, not in the open flow job execution, the normal blanking plug that adopts seals in the tubing string, but because a variety of causes such as down-hole pressure is big, wax deposition, fouling, sometimes blanking plug normally can not be rendered to the precalculated position in the downhole oil tubing string, and construction can't be carried out.
The purpose of this utility model: be to provide a kind of blanking plug delivery device for the oil-water well snubbing serving, in running into the big or tubing string of down-hole pressure during situation such as wax deposition, fouling, can by force blanking plug be rendered to the precalculated position, guarantee that underground work construction normally carries out.
The purpose of this utility model realizes by following measure: a kind of blanking plug delivery device comprises hydraulic cylinder, traveling slip, stationary slip, self-sealing blowout preventer, central tube, atmospheric valve, partly seals blowout preventer and lower contact etc.; It is characterized in that one by three middle parts, upper, middle and lower crossbeam with holes and between the support formed of hydraulic cylinder, the central tube upper end that has half envelope blowout preventer and atmospheric valve of installing on its lower transverse beam links to each other with the self-sealing blowout preventer above being installed in middle cross beam, the lower end links to each other with lower contact below the lower transverse beam, stationary slip is installed above the self-sealing blowout preventer, on support, below top rail that hydraulic cylinder piston links to each other, traveling slip is installed.
This real new structure is simple, easy to process, reliable operation, easy operating, under being used for not kill-job of oil-water well, the situation that is not hampered in the open flow operation oil pipe, can be by force with blanking plug down to any precalculated position, normally carry out to guarantee construction.
Fig. 1 is a blanking plug delivery device structural representation.
The blanking plug delivery device by support 10, hydraulic cylinder 2, traveling slip 3, stationary slip 4, self-sealing blowout preventer 6, central tube 7, atmospheric valve 8, partly seal blowout preventer 9 and lower contact 11 etc. and form; The crossbeam that three middle parts, upper, middle and lower are with holes and between the support 10 formed of hydraulic cylinder 2, central tube 7 upper ends that have half envelope blowout preventer 9 and atmospheric valve 8 of installing on its lower transverse beam link to each other with the self-sealing blowout preventer 6 above being installed in middle cross beam, the lower contact 11 of lower end below lower transverse beam links to each other, stationary slip 4 is installed above the self-sealing blowout preventer 6, traveling slip 3 is installed below the top rail that on support 10, links to each other with hydraulic cylinder 2 pistons.
Operating principle of the present utility model and using method are: earlier the blanking plug delivery device is installed on the well head high pressure valve of the well of waiting to construct by lower contact 11, opens and partly seal blowout preventer 9 and atmospheric valve 8 on the central tube 7; The oil pipe 1 that to throw in usefulness again installs self-sealing blowout preventer 6 upper ends by support 10 top rails, traveling slip 3 and stationary slip 4, and connects with blanking plug 5; Can transfer blanking plug 5 to self-sealing blowout preventer 6 this moment by oil pipe 1, closes atmospheric valve 8, just can continue to transfer blanking plug 5 by oil pipe 1 and enter in the tubing string of down-hole through central tube 7, lower contact 11; The Shi Zeke that is hampered drives support 10 by hydraulic cylinder 2 and 3 pairs of oil pipes 1 of traveling slip pressurize when transferring, and matches with stationary slip 4, just can be with the precalculated position of blanking plug 5 snubbing downhole oil tubing strings.
