Description
Technical field
The utility model is the equipment that the oilfield oil well band presses workover treatment to use, and is a kind of not kill-job Operating Pressure device.
Background technology
When having the oil-water well of pressure to need construction operation for well head, generally all adopt the high density well killing fluid to carry out kill-job, make pit shaft head of liquid stressor layer above Ground, make its operation well head not have pressure.Adopt the way of kill-job to eliminate well head pressure, need lot of manpower and material resources, also can cause formation contaminant, cause that formation pore is blocked, influence field produces, cause heavy economic losses.Problem at above-mentioned existence, the relevant technologies staff development band press the workover treatment device, make it when well head has under the situation of pressure operation, not need kill-job, as Chinese patent application 200720173181.3 " monolithic high pressure profit Operating Pressure device ", realize the equipment of snubbing serving exactly.But this technology will adopt annular preventer to dispose the purpose that multiple ram preventer could be realized invention, thereby the appearance and size of package unit is big, assembly is many, and the cost height is placed on the height that has surpassed the permission transportation on the transport vehicle, therefore can only split the back transportation, arrived the well site and be mounted to one again and carry out operation, so construction sequence is many when adopting it to carry out snubbing serving, time is long, and it is big to apply difficulty.
Summary of the invention
The purpose of this utility model is the deficiency that exists in the above-mentioned technology; design a kind of not kill-job Operating Pressure device; make its assembly few; appearance and size is little, can whole carry, and reduces cost and working procedure; be convenient to applying of snubbing serving; avoid the oil-water well kill job, the oil field development effect is improved on the protection stratum.
The purpose of this utility model is achieved in that and comprises traveling slip, crossbeam moves about, rotary flange, bracing frame, hydraulic lift, operating platform, bracing frame is installed in around the wellhead assembly, bracing frame upper end fitting operation platform, the hydraulic cylinder of hydraulic lift is fixed on the bracing frame, the crossbeam that moves about is installed in the plunger upper end of hydraulic lift, traveling slip is installed on the crossbeam that moves about, also comprise first envelope, upper slips, in half envelope, go up full envelope, second envelope, lower slips, seal entirely down, first envelope, upper slips, in half envelope, go up full envelope and form four flashboard control device, second envelope, lower slips, full envelope is formed three flashboard control device down, three flashboard control device are installed on the well head big four, on the three flashboard control device rotary flange is installed, four flashboard control device are installed on the rotary flange, on the four flashboard control device self-packer is installed, the crossbeam that moves about is on the self-packer.
The full bottom of sealing is installed on the well head big four down, on the full envelope lower slips is installed down, second envelope is installed on the lower slips, on second envelope rotary flange is installed, install full envelope on the rotary flange, go up install on the full envelope in half envelope, in install slips on half envelope, first envelope is installed on the upper slips.
The beneficial effects of the utility model are: by alternately switching three flashboard control device, assembly on the four flashboard control device and the lifting of operating hydraulically operated lifting gear, just can realize being with the kill-job snubbing serving, can and be lowered to the proposition of the existing major diameter downhole tool (length is less than 1.2m) of compacting, the utility model does not need to install annular preventer, make it simple in structure, appearance and size is little, can whole carry, do not need to assemble at the construction field (site), each parts is all in indoor assembling, pressure testing, detect, can ensure the quality of products, satisfy the blowout prevention requirement, therefore, the utility model can reach purpose of design, has remarkable economic efficiency.
Description of drawings
Accompanying drawing is the assembling drawing of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described.
As shown in the figure, embodiment of the present utility model comprises traveling slip 1, crossbeam 2 moves about, self-packer 3, first envelope 4, upper slips 5, in partly seal 6, go up full envelope 7, rotary flange 8, bracing frame 9, hydraulic lift 10, second envelope 11, lower slips 12, seal 13 entirely down, operating platform 14, bracing frame 9 be installed in wellhead assembly around, in order to keep stable bracing frame 9 to have four symmetries to install, bracing frame 9 upper end fitting operation platforms 14, the workman may stand on the operating platform 14 and works, the hydraulic cylinder of hydraulic lift 10 is fixed on the bracing frame 9, the crossbeam 2 that moves about is installed in the plunger upper end of hydraulic lift 10, traveling slip 1 is installed on the crossbeam 2 that moves about, the crossbeam 2 that moves about rises or landing with hydraulic lift 10, first envelope 4, upper slips 5, in partly seal 6, go up full envelope 7 and form four flashboard control device, second envelope 11, lower slips 12, full envelope 13 is formed three flashboard control device down, three flashboard control device are installed on the well head big four, rotary flange 8 is installed on the three flashboard control device, four flashboard control device are installed on the rotary flange 8, self-packer 3 is installed on the four flashboard control device, and the crossbeam 2 that moves about is on the self-packer 3.Complete 13 bottoms of sealing are installed on the well head big four down, on the full envelope 13 lower slips 12 is installed down, second envelope 11 is installed on the lower slips 12, rotary flange 8 is installed on second envelope 11, install full envelope 7 on the rotary flange 8, go up and partly to seal 6 in installing on the full envelope 7, in partly seal and install slips 5 on 6, first envelope 4 is installed on the upper slips 5.According to circumstances, each parts on four flashboard control device, the three flashboard control device can be adjusted the position.
