Problems solved by technology

The system is easy to realize the discharge operation, occupies a small space, and is light in weight, but the working radius is small and the control is complicated. It usually needs to be used in conjunction with other discharge systems on the drilling floor
However, when the drill string is suspended, the stress on the middle and upper sections of the derrick and the second-floor platform is relatively complicated, which is not conducive to the transformation of the drilling rig in use; at the same time, the row of drill strings and drill strings are placed vertically, and the stability is poor, so it has not yet been applied industrially.

Abstract

The invention relates to petroleum drill and exploitation equipment, in particular to an automatic discharge device for drill strings. A top drive is arranged at the top of a derrick, a two-layer platform is arranged in the middle, and a drill floor is arranged at the lower part; a stand platform is connected to the drill floor; an upper manipulator is connected to the two-layer platform and can move on the two-layer platform; a lower manipulator support is connected to the stand platform; a lower manipulator is connected to the lower manipulator support and can move on the lower manipulator support. The device can grip, move and discharge the drill strings automatically, reduces the labor intensity of workers, and is high in mechanical degree, safe to operate and applicable to various drilling platforms.

Description

technical field [0001] The invention belongs to the technical field of petroleum drilling and production equipment, and relates to a drill pipe discharging device for grasping, moving and discharging vertical roots. Background technique [0002] Drill pipe discharge is the process of conveying and discharging the stand between the stand and the wellhead during the drilling process. During the drilling operation, a large number of drill string discharge operations are required, including the discharge of the drill string on the well site and the discharge on the drill floor. Especially in the tripping process, it is necessary to repeat the drill string discharge operation many times. The drill string discharge operation not only takes a lot of time, but also has high labor intensity and high safety risk. Therefore, to realize the automatic discharge of the drill string, keep the driller away from the dangerous area, reduce the labor intensity of the workers, improve the aut...
