Abstract
A wheel type slip continuous loading operation device with pressure comprises a fixed gripper tube device, a full seal, a half seal, a ball seal, an operation platform and a support, wherein the operation platform and the support are mounted together with the ball seal. A roller wheel type slip machine mounted on the support comprises two boxes, roller wheels and roller wheel shafts, the roller wheels and the roller wheel shafts are mounted inside the boxes, hydraulic motors are mounted at the ends of the boxes and connected with the roller wheel shafts, a clamping hydraulic cylinder is mounted on the lateral surface of one box, a pull rod is connected onto a coupling shaft of the clamping hydraulic cylinder, and the pull rod is fixed with the other box by the aid of a fastening nut. The device has the advantages of strong functions, adaptability to high-pressure oil-water well continuous loading operation with pressure, low operation platform capable of matching with minor repair, simple operation procedure, fast speed, time, labor and cost economization, safety, reliability and practicality, and is widely applied to oil exploitation downhole operation process.
Description
One, technical field:
The present invention relates to apparatus for work under the oil well, particularly a kind of wheel type slip continuous loading device operating under pressure.
Two, background technology:
Traditional oil-water well band has been pressed lower tubular column, generally is that the fixedly pipe clamping device by the Operating Pressure device, the pipe clamping device fluid,matching cylinder pressure that moves about realize that have following shortcoming: 1. can not realize working continuously, operation procedure is many, and speed is slow; 2. the pipe clamping device slip insert damages easily, and application life is short; 3. the job platform height is difficult for light maintenance supporting.4. the structure component number is many, installation, maintenance, complicated operation, and labour intensity is big, cost is high.
Three, summary of the invention:
The purpose of this invention is to provide a kind of wheel type slip continuous loading device operating under pressure, adopt roller type slips, hydraulic motor and the supporter combining structure of symmetry, the positive and negative rotation of fluid motor-driven roller type slips, roll tubing, realize removing of tubing string, overcome or avoid the shortcoming or the deficiency of above-mentioned prior art effectively.
Wheel type slip continuous loading device operating under pressure of the present invention comprises that fixedly pipe clamping device, full envelope, half envelope, ball sealing reach operating platform and the supporter that is installed together with ball sealing.Roller type slips device is installed on the described supporter, roller type slips device comprises the roller and the roller shaft of casing and interior installation thereof, described casing is two, its end is equipped with hydraulic motor, this hydraulic motor is connected with roller shaft, the side of one casing is equipped with the clamping hydraulic cylinder, is connected with pull bar on the shaft coupling of this clamping hydraulic cylinder, and pull bar is fixed by fastening nut and another casing.
Wherein, described supporter is two, and each is connected with the bottom of two casings.Described hydraulic motor is two, respectively is connected in two ends that casing is relative.Described clamping hydraulic cylinder is two, is installed on the diagonal up and down of a casing side.Described roller and roller shaft connect as one, and an end is connected with hydraulic motor, on an end and the other end bearing are installed.
The present invention has following advantage compared with prior art:
1, function is strong, adapts to the hydraulic oil well and loads Operating Pressure continuously;
2, reduce job platform, can be supporting with light maintenance;
3, operation procedure is simple, and speed is fast, saves time, laborsaving, cost-saving;
4, safe, reliable, practical.
Four, description of drawings
Fig. 1 is a kind of example structure schematic diagram of the present invention
Fig. 2 is for pressing roller type slips device A-A shown in Figure 1 to structural representation
Five, the specific embodiment
Consult Fig. 1-Fig. 2, a kind of wheel type slip continuous loading device operating under pressure comprises fixing pipe clamping device 1, seals 2 entirely, partly seals 3, ball sealing 6 and the operating platform 5 and the supporter 4 that are installed together with ball sealing 6.Roller type slips device 50 is installed on the supporter 4.Roller type slips device 50 comprises the roller 15 and the roller shaft 12 of casing 7 and interior installation thereof.Casing 7 is two, its end is equipped with hydraulic motor 8, and this hydraulic motor 8 is connected with roller shaft 12, and the side of a casing 7 is equipped with clamping hydraulic cylinder 9, be connected with pull bar 16 on the shaft coupling 11 of this clamping hydraulic cylinder 9, pull bar 16 is fixed by fastening nut 14 and another casing 7.
During the operation of hydraulic oil well, when borehole pressure during greater than tubing string weight in order to overcome the last top power of tubing string, prevent that pipe from scurrying and flying pipe, need load lower tubular column.The continuous loaded ribbon that can efficiently remove the hydraulic oil well tubing is pressed apparatus for work, drives symmetrical roller type slips device 50 positive and negative rotations by hydraulic motor 8, and roll tubing is realized removing of tubing string, and operating speed significantly improves.
