Batch pipe column conveying device and pipe column processing method

Abstract

The invention discloses a batch pipe column conveying device and a pipe column processing method. The batch pipe column conveying device comprises a lower section drill column conveying device and an upper section drill column conveying device which are connected through a chain guide device, wherein a transmission round-link chain is further arranged between the lower section drill column conveying device and the upper section drill column conveying device, and a catwalk base is arranged at the bottom of the lower section drill column conveying device; a drill floor is arranged on one side of the catwalk base, a drill floor idle wheel assembly is welded on the drill floor, the lower portion of the upper section drill column conveying device can be in lap joint with a rolling shaft of the drill floor idle wheel assembly, a support assembly and a lifting hydraulic cylinder are arranged between the lower section drill column conveying device and the catwalk base, and a pipe arranging frame is arranged on the catwalk base. The upper section drill column conveying device and the lower section drill column conveying device can carry a plurality of pipe columns to be rapidly unfolded during lifting, after the pipe columns are unfolded to a proper angle, a small tackle can push the pipe columns to directly reach a proper position of the drill floor from the lower section of the drill column conveying device, meanwhile, the pipe columns can be separated one by one, and connection of an elevator and a single pipe column is facilitated.

Description

technical field

[0001] The invention belongs to the technical field of petroleum drilling development, and in particular relates to a batch pipe string conveying device, and also relates to a pipe string processing method of the conveying device. Background technique

[0002] At present, on land oil drilling rigs, the pipe string automation system has been started one after another. The pipe string conveying device is one of the pipe string automation system equipment. The pipe string is transported back to the ground. This equipment can be operated remotely without human intervention, which reduces the labor intensity of drilling workers, reduces operational risks, and improves the pipe string transportation efficiency.

[0003] However, there are generally some problems in the existing pull-up and lift-type pipe string conveying devices, such as long operation period (the whole process of conveying the pipe string up / down the drill floor) and one working cycle can only tra...
