Iron driller

Abstract

The invention provides an iron roughneck, which relates to an assorted wellhead operation device of a petroleum drilling machine and aims at solving the problem of inconvenient operation in the prior art. The wellhead operation device comprises a tong head assembly, a support arm assembly and an electrohydraulic control system; the tong head assembly comprises a spinner assembly, a driving tong assembly and a driven tong assembly as well as a lifting mechanism and a swing mechanism. One end of the support arm assembly is movably connected on the lifting mechanism while the other end is movably connected with the swing mechanism. The swing mechanism is connected with the driving tong assembly and the driven tong assembly; the tong head assembly is arranged above the driving tong assembly and the driven tong assembly; the electrohydraulic control system consists of a hydraulic control system and an electronic control system; the swing mechanism, the lifting mechanism, the support arm assembly, the spinner assembly, the driving tong assembly and the driven tong assembly respectively contain respective hydraulic cylinder drive parts and the hydraulic cylinder drive parts of all the assembly are connected with and controlled by the hydraulic control system; and the electronic control system controls the hydraulic control system. The wellhead operation device is applicable to wellhead operation during petroleum drilling.

Description

technical field [0001] The invention belongs to oil drilling and production equipment, in particular to a wellhead operating device matched with an oil drilling rig. Background technique [0002] At present, in the domestic oil drilling industry, the operation of drilling and lowering the drill pipe is manual, and the labor intensity is very high. Manual operation of the drilling and lowering of the drill pipe also brings safety risks to the operators, and the labor cost also increases. increase. [0003] The iron drill is called a revolutionary high-tech product by the petroleum industry, and it is widely used in land and offshore oil drilling operations, and belongs to the wellhead operation device. Iron drillers can greatly reduce the number of workers at the wellhead, reduce the labor intensity of workers, and greatly improve operating efficiency. At present, there is no domestic enterprise that can produce them. [0004] Internationally, the iron drillers produced by ...

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem of inconvenient operation in the prior art, and to provide a brand-new iron driller as a wellhead robot for wellhead operations, which can make the jaws align with the deviated drilling tools located in the rat hole, and swing through it The deflection and swing of the mechanism causes the entire clamp head assembly to deflect at a certain angle, thereby solving the operation problem of the single rod connected to the mouse hole, solving the problems caused by domestic manual operation, and providing cheaper, Alternatives with superior performance
