Due to utilization of the device, pressure inspection and lower rod construction operation of the pumping well can be smoothly finished without well killing and blowout.
Description
Technical field:
The utility model relates to a kind of particularly wellhead assembly of Operating Pressure of oil field pumping well underground work that is used for.
Background technology:
At present, the scene, oil field in oil-water well underground work process, for protect oil reservoir not the reason kill-job oil reservoir is damaged or pollutes, adopt not kill-job Operating Pressure usually.Yet existing Operating Pressure refers to water injection well or land whale when constructing basically, relies on tubing plug to match with special-purpose preventer, by device for exerting, does not play lower tubular column under the condition of open flow in not kill-job, carries out construction operation.But pressed the sucker rod operation for the pumpingh well band, because of blowout hookup can't be installed, cause and can't construct, reason is that pumpingh well open flow and polished rod can't be dismantled.
The utility model content:
The utility model purpose is to provide a kind of can be with not kill-job of the pumpingh well inspection bar apparatus for work of pressing dismounting blowout prevention box and polished rod, finishing inspection, lower beam job execution under the situation of not kill-job.
The utility model purpose is to realize like this.Not kill-job of this kind inspection bar apparatus for work comprises preventer main body and extraordinary sealing jamming rod device two parts, wherein the preventer main body is by box cupling, short circuit, annular preventer, hydraulic line joint, blind pipe, open flow valve, screw thread head, sucker rod ram preventer are formed up and down, its structure assembled relation is as follows: go up the annular preventer upper end and link to each other with box cupling by short circuit, the lower end is connected with the blind pipe upper end, and the blind pipe lower end is connected with following annular preventer upper end; Following annular preventer lower end is connected with the sucker rod ram preventer by the screw thread head, and sucker rod ram preventer lower end is connected to the screw thread head; The annular preventer both sides are respectively equipped with the hydraulic line joint up and down, and the blind pipe both sides respectively are provided with an open flow valve.Extraordinary sealing jamming rod device is made up of crank rocking arm, drive shell, leading screw housing, seal casinghousing, screw thread head, packing unit flashboard, the crank rocking arm is equipped with in the drive shell top, drive shell, leading screw housing, seal casinghousing are connected from top to bottom successively, and the seal casinghousing below is connected with the packing unit flashboard by the screw thread head.During the operation of pumpingh well inspection bar, at first set little four-way and produce the extraordinary sealing of valve both sides installation jamming rod device, during butt joint, make packing unit parallel with the curve of well head at well recovery; Then, open both sides and produce valve, on carry polished rod and make first rod collar be higher than little four-way, the rocking arm that turns clockwise moves ahead packing unit, closes extraordinary sealing jamming rod device, seals liquid in the oil pipe, embraces sucker rod simultaneously and prevents to glide; Dismounting blowout prevention box is torn polished rod open; The preventer main body is installed, connects hydraulic line, open two annular preventers and sucker rod ram preventer, dock with sucker rod screw thread in the well head, close and close annular preventer, open extraordinary sealing jamming rod device with the sucker rod short circuit; On when carrying sucker rod and treating that box cupling arrives in the middle of two annular preventers, close down annular preventer, open annular preventer; Carry sucker rod in the continuation, treat that box cupling passes through last annular preventer after, close and to close annular preventer, open down annular preventer, lay down sucker rod; Repeat the method for operating of a sucker rod, tripped out full well sucker rod; When piston base exceeds the sucker rod ram preventer, close full envelope sucker rod ram preventer.The lower sucker rod method of operating is opposite with a sucker rod method of operating.
The utility model novel structure, reasonable in design, reliable operation utilizes it can finish not kill-job of the pumpingh well not inspection of open flow band pressure, lower beam construction operation smoothly, and this device also has advantages such as volume is little, easy to operate, saving cost.
Description of drawings:
Fig. 1 is the structural representation of the utility model preventer main body.
Fig. 2 is extraordinary sealing jamming rod device structural representation.
The specific embodiment:
Below in conjunction with accompanying drawing enforcement of the present utility model is illustrated.
As shown in Figure 1, the utility model preventer main body is made up of box cupling 1, short circuit 2, upper and lower ring packing device 3,6, hydraulic line joint 4,7, blind pipe 5, open flow valve 12, screw thread head 8,9,11, sucker rod ram preventer 10.Wherein, box cupling 1, short circuit 2 sizes are
89mm. Ring packing device 3,6 is formed by housing, spherical glue core and annular cylinder up and down, high 580mm.Blind pipe 5 external diameter 110mm, internal diameter 76mm, long 1590mm.Sucker rod ram preventer 10 is made up of housing, sealing damper and driving oil cylinder, high 200mm.
As shown in Figure 2, extraordinary sealing jamming rod device is made up of crank rocking arm 13, drive shell 14, leading screw housing 15, seal casinghousing 16, screw thread head 17, packing unit flashboard 18.
