Drill site tubular pile automatic discharging device

Abstract

The invention relates to an automatic string handling device in well fields, being characterized in comprising a movable lifting device and a multi-layer pipe rack, the movable lifting device comprises a rail on which two lifting cylinders are arranged in a sliding way and one side of which a dragging device used to drag two lifting cylinders is arranged, the tops of plunger pistons of the two lifting cylinders are respectively connected with a set of runners rotationally through a driving device; one side of the movable lifting device is provided with the multi-layer pipe rack. The automatic string handling device in well fields can also be provided with a lifting pipe bridge between the movable lifting device and the multi-layer pipe rack; realizes the automation of the link of handling strings, is strongly applicable and can be used in similar automatic handling operation.

Description

technical field [0001] The invention relates to a pipe string discharge device, in particular to an automatic well site pipe string discharge device used in drilling and workover operations. Background technique [0002] At present, in our country, when drilling and workover operations on oil well sites, the discharge of pipe strings needs to be done manually by workers. During the operation (as shown in Figures 1a to 1d), one end of the pipe string 4 is first clamped with a spreader and lowered to the drill floor surface 51. When the bottom end of the pipe string 4 is close to the drill floor surface 51, the pipe string 4 is manually pushed to the On the slideway 52, when the top of the pipe string 4 is lowered close to the drill floor, the spreader is removed, and then the pipe string 4 is manually pulled onto the catwalk 53 (as shown in Figure 1c), and then the pipe string is pulled from the catwalk 53 4Push onto the tube holder 54. It can be seen from the above process...

AI Technical Summary

Problems solved by technology

It can be seen from the above process that the catwalk 53 is fixed, and the pipe string 4 is pushed onto the slideway 52, then pulled onto the catwalk, and finally pushed onto the pipe frame 54. This series of processes all require manual adjustment of the pipe string. 4 to operate, and the same catwalk 53 can only discharge the pipe string 4 to the pipe rack 54 of the same height, and layer discharge cannot be realized, so the operation efficiency is very low, the workload of the operator is large during the discharge process, and there are potential safety hazards
