A well site pipe string automatic discharge device

Abstract

The invention relates to an automatic discharge device for well site pipe strings, which is characterized in that it includes a mobile lifting device and a multi-layer pipe rack, the mobile lifting device includes a track, and two slides are arranged on the track. As for the lifting cylinder, a dragging device for dragging the two lifting cylinders is arranged on one side of the track, and the tops of the plungers of the two lifting cylinders are respectively connected to a group of slideways through a driving device; the mobile One side of the lifting device is provided with the multi-layer rack. In the present invention, a lifting pipe bridge can also be arranged between the mobile lifting device and the multi-layer pipe rack. The invention realizes the automation of the pipe column discharge link, has strong applicability, and can be popularized and applied to similar automatic discharge operations.

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 operation (such as Figure 1a-1d As shown), first clamp one end of the pipe string 4 with a spreader and lower it to the drill floor surface 51. When the bottom end of the pipe string 4 is close to the drill floor surface 51, manually push the pipe string 4 onto the slideway 52. ​​When the pipe string 4 After the top is lowered close to the drill floor surface, the spreader is removed, and then the pipe string 4 is manually pulled onto the catwalk 53 (such as Figure 1c Shown), then pipe string 4 is pushed onto pipe rack 54 from catwalk 53. It can be seen from the above process that the catwalk 53 i...

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
