Abstract

The present application belongs to the technical field of oilfield workover, and discloses a tubing conveying device for workover site, aiming at solving the problems of high labor intensity and low overall efficiency in tubing conveying operation at workover site. The device comprises a base, a supporting arm, a connecting sleeve, and a detachable clamping, driving and fixing assembly. The supporting arm moves horizontally through a sliding assembly, the clamping height is controlled by a lead screw and a motor, and the angle of the supporting frame is adjusted by a rotating assembly. The clamping assembly uses an arc-shaped claw with balls to grab the tubing and allow it to rotate. The driving assembly controls the opening and closing of an arc-shaped claw through a hydraulic cylinder, and is provided with a rotatable arc-shaped plate to drive the tubing to make up and rotate. The fixing assembly fixes the tubing in the well through an arc-shaped claw. The device can realize the grabbing, translation, make-up and rotation of the tubing from the tubing rack to the wellhead, greatly reducing the labor intensity, improving the operation efficiency and safety, and being suitable for tubing lowering and lifting operation at workover site.
