Tubing shifting conveying device and using method thereof

Abstract

The invention relates to the technical field of petroleum engineering equipment, and provides a tubing shifting conveying device and a using method thereof. The tubing shifting conveying device comprises a mounting seat, bearing seats, a transmission shaft, a bearing body, shifting wheels and a power driving device, wherein the at least two bearing seats are fixed to the mounting seat in the front-rear direction at intervals, and the transmission shaft sequentially penetrates through the middle of the corresponding bearing seat from front to rear; the front end of the transmission shaft is located in front of the bearing seat on the front side, the rear end of the transmission shaft is located behind the bearing seat on the rear side, and the bearing body is mounted between the transmission shaft and the bearing seats; and the at least two shifting wheels are fixed to the outer side of the transmission shaft in the front-rear direction at intervals. The using method of the tubing shifting conveying device comprises the step that 1, the tubing shifting conveying device is placed at a wellhead to make the left side of the tubing shifting conveying device be close to an existing tubing temporary storing place. According to the tubing shifting conveying device and the using method thereof, automatic shifting conveying operation of an tubing can be achieved through change of a clamping opening from one position to another position; and whole shifting conveying operation is easy and convenient, both time and labor are saved, continuous shifting conveying operation can be achieved, the shifting conveying efficiency is high, and manual carrying is not required.

Description

technical field [0001] The invention relates to the technical field of petroleum engineering equipment, and relates to an oil pipe transfer device and a use method thereof. Background technique [0002] In the conventional workover operations of oil and water wells, it is basically all to be pulled and carried by manpower. In the operation of lowering the tubing, usually the workover three-post personnel manually roll the tubing from the rear end of the tubing bridge to the side of the tubing slideway, and then the three-post personnel lift it onto the tubing block on the tubing slideway and push it to the wellhead for convenience. The wellhead worker buckles the elevator. The average weight of a φ73mm tubing is 90kg, and the depth of a well is 2000m. The lifting and lowering operation of a pipe string is equivalent to handling a weight of 30-40 tons. The labor intensity of the workers is high, and the safety factor is low, requiring a degree of cooperation among personnel....

AI Technical Summary

Problems solved by technology

[0003] The present invention provides a oil pipe transfer device and its use method, which overcomes the deficiencies of the above-mentioned prior art, and can effectively solve the cumbersome operation existing in the operation of the existing transfer hook, the transfer efficiency is low, and there are potential safety hazards. When drilling the pipe, it cannot be thrown to the top automatically, and manual handling is required, which is a problem with large limitations.
