Description
Technical field
The present invention relates to major diameter tool method in a kind of back-off combination tool and with pressure gas well well.
Background technology
At present, Operating Pressure removes OIH tubing string, mostly is blank tubing tubing string, and oil pipe blocking instrument by the latus rectum of oil pipe, can arrive at the afterbody of tubing string, block in oil pipe, adopts operation device under pressure, can trip out all with pressure for OIH pipe on ground.
But in the reservoir reconstruction work progress of gas well, normal employing fixed tubular column separate stratum fracfturing technique, the major diameter instrument of reservoir reconstruction is together lowered in well together with tubing string by this technique determines position, by the mode of pitching, change the duty of down-hole major diameter instrument, thus realize the separate zone stimulation to different reservoir, in whole reservoir reconstruction and recovery process, fixed tubular column, major diameter instrument together uses as gas production tubing string with tubing string.
When gas-bearing formation generation water logging or pit shaft accident, need to carry out Operating Pressure and trip out tubing string, and measure process is carried out to pit shaft or reservoir, now because containing major diameter instrument (hydraulic anchor, packer etc.) in tubing string, major diameter instrument in well cannot be proposed well head by conventional belt pressed operation technique.
Summary of the invention
The technical problem to be solved in the present invention is to provide major diameter tool method in a kind of back-off combination tool and with pressure gas well well, to overcome the defect existed in existing with pressure major diameter drilling tool technology.
Technical scheme of the present invention is: a kind of back-off combination tool, is characterized in that: comprise the rotation short circuit, telescopic compensator and the back-off short circuit that connect successively.
Described rotation short circuit, telescopic compensator and back-off short circuit length are 65-100cm, and external diameter is 73-114mm; Upper lower contact is API standard 2
7/
8in external upset tubing is buckled.
A major diameter tool method in pressure gas well well of the back-off combination tool that profit is above-mentioned, is characterized in that, comprise following steps:
1] major diameter instrument is risen to Operating Pressure machine two and work between preventer, and adopt slips preventer that following for major diameter instrument oil pipe is clamped and pinned;
2] back-off combination tool is connected at well head;
3] enter back-off combination tool under in Operating Pressure machine at well head by after blocking oil pipe back-off, trip out well head;
4] again in Operating Pressure machine, use back-off combination tool, back-off is carried out to major diameter instrument, the tubing string back-off that itself and bottom connect is separated, the major diameter instrument after being separated is tripped out operation device under pressure;
5] reuse back-off combination tool, rotate and pour out large diameter oil tube in Operating Pressure machine, until complete.
Technique effect of the present invention is:
1, the present invention in Operating Pressure construction, can transmit 3000N.m moment of torsion, bears 30MPa pressure, load-bearing 30 tons.
2, the present invention can in S-9 Operating Pressure machine, and in band well in the non-shutoff situation of instrument, back-off trips out major diameter instrument in well step by step.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of back-off combination tool in the present invention.
Reference numeral is:
1-the first oil pipe joint hoop, 2-rotate short circuit, the 3-the second oil pipe joint hoop, 4-telescopic compensator, the 5-the three oil pipe joint hoop, 6-back-off short circuit.
Detailed description of the invention
The present invention relates to that gas field is with pressure repaiies completion practice field, with pressurely trip out major diameter tool method in gas well well and can solve the difficult problem that major diameter instrument with pressurely cannot trip out Wellbore of Gas Wells, save the construction used time, reduce construction risk, truly realize the trip-out construction with pressure of tubing string in gas well well.
See Fig. 1, the concrete structure of a kind of back-off combination tool that the present invention relates to is as follows:
Comprise the rotation short circuit 2, telescopic compensator 4 and the back-off short circuit 6 that connect successively.Wherein, rotate short circuit and be used for the moment of torsion that transmission fluid pressing tongs provides, coordinate with annular preventer simultaneously, realize wiper seal; Telescopic compensator is used for transmitting the moment of torsion rotating short circuit transmission and come, and simultaneously in shackle process, the axial distance that compensation screw thread flight lead produces compensates; Back-off short circuit is used for contacting with instrument in well, in conjunction with, transmission telescopic compensator loads the moment of torsion above it simultaneously.Rotate short circuit 2, be specifically connected by the first oil pipe joint hoop 1, second oil pipe joint hoop 3, the 3rd oil pipe joint hoop 5 between telescopic compensator 4 and back-off short circuit 6.
Rotation short circuit 2 in the present invention, telescopic compensator 4 and back-off short circuit 6 length are 65-100cm, and external diameter is 73-114mm; Upper lower contact is that API standard 27/8in external upset tubing is buckled, and can directly connect.
Major diameter tool method in a kind of with pressure the gas well well utilizing above-mentioned back-off combination tool that the present invention relates to, comprises following steps:
1] risen by major diameter instrument to Operating Pressure machine two and work between preventer, and adopt slips preventer that following for major diameter instrument oil pipe is clamped and pinned, this step is carried out at the Operating Pressure hands-operation of well head;
2] connect back-off combination tool at well head, namely connect the combination tool related to by the present invention rotating short circuit 2, telescopic compensator 4, back-off short circuit 6 are formed;
3] enter back-off combination tool under in S-9 Operating Pressure machine at well head by after blocking oil pipe back-off, trip out well head;
4] again in S-9 Operating Pressure machine, use back-off combination tool, back-off is carried out to major diameter instrument, the tubing string back-off that itself and bottom connect is separated, the major diameter instrument after being separated is tripped out operation device under pressure;
5] reuse back-off combination tool, rotate and pour out large diameter oil tube in S-9 Operating Pressure machine, until complete.
Operating Pressure machine specifically can be S-9 Operating Pressure machine.
The parts that the present embodiment does not describe in detail and structure belong to the well-known components of the industry and common structure or conventional means, do not describe one by one here.
