Abstract
The invention discloses a rotating nipple for hydraulic shaping and relates to a rotating nipple, solving the problems that the shaping orientation of a power motor is uncertain, and the power motor has failure and is damaged under the action of hydraulic pressure and a reactive torque. In the invention, a steering rod is inserted in a rotating sleeve, and a positioning hole is arranged on the rotating sleeve; a positioning pin is inserted in the positioning hole and used for positioning the steering rod and the rotating sleeve; the lower end of an upper joint is inserted in the rotating sleeve as well as sleeved at the upper end of the steering rod; the upper part of a lower joint is inserted at the lower end of the rotating sleeve, and the upper end surface of the lower joint is in contact with the lower end surface of the steering rod; a guide block is arranged on the lower part of the steering rod, and a stop block is arranged below the guide block; and the upper end of the stop block is in contact with the guide block. The rotating nipple replaces the traditional hydraulic motor, achieves the purpose of omnibearing shaping and guarantees the shaping effect.
Description
Technical field
The present invention relates to a kind of rotating short-knot, be specifically related to a kind of rotating short-knot that is used for the shaping of coiled tubing hydraulic pressure.
Background technology
At present, when utilizing coiled tubing to carry out the hydraulic pressure shaping, need tubing string constantly to slowly run, could guarantee shaping effect, but coiled tubing hydraulic pressure shaping tubing string can not rotate, be to connect power motor on coiled tubing hydraulic pressure shaping tubing string at present, the oil pipe bottom is rotated under not shaping situation, but the oil pipe rotating speed is too fast, and when continuing shaping again, the shaping orientation is uncertain; And power motor is subjected to hydraulic pressure and reaction torque effect when shaping, causes power motor to lose efficacy and damages.
Summary of the invention
The objective of the invention is to cause the power motor problem of damage that lost efficacy, and then a kind of rotating short-knot that is used for the hydraulic pressure shaping is provided for solve adopting the uncertain and power motor in power motor shaping orientation to be subjected to hydraulic pressure and reaction torque effect.
The present invention solves the problems of the technologies described above the technical scheme of taking to be: the rotating short-knot that is used for the hydraulic pressure shaping of the present invention comprises lower contact, stop block, guide pad, turnbarrel, turning-bar, alignment pin and top connection, described turning-bar is inserted in the turnbarrel, be processed with locating hole on the described turnbarrel, described alignment pin is inserted in the locating hole, described alignment pin is used for locating between turning-bar and the turnbarrel, the lower end of described top connection is inserted in the turnbarrel, and the lower end of top connection is sleeved on the upper end of turning-bar, the top of described lower contact is inserted into the lower end of turnbarrel, and the upper surface of lower contact contacts with the lower surface of turning-bar, described guide pad is positioned at the bottom of turning-bar, described stop block is positioned at the below of guide pad, and the upper surface of stop block contacts with guide pad.
The invention has the beneficial effects as follows: the rotating short-knot that is used for the hydraulic pressure shaping of the present invention has substituted existing hydraulic motor, when having realized the hydraulic pressure shaping, upper lifting pipe post rotation shaping tool orientation, cover is decreased the position implement other orientation shaping, and finally realize the purpose of comprehensive shaping having guaranteed shaping effect; Rotating short-knot of the present invention is simple in structure, use is reliable, and success rate can reach 100%.
