Problems solved by technology

[0003] The purpose of the present invention is to solve a series of problems such as the transportation and measurement of the current drilling pipe string from the ground to the drill floor, the make-up / breakout and suspension of the pipe string on the drill floor, the delivery of the drill during drilling, and the access of the vertical root during tripping. In the operation, there are problems of high altitude, multi-person cooperation, high labor intensity, high risk, and low efficiency. An automatic operating system for drilling strings for automatic upgrading and transformation of drilling rigs is provided to overcome the existing drilling rigs that are only equipped with automatic catwalks. Single or several automatic devices for machine or power slips or vertical root automatic discharge devices only reduce local labor intensity and fail to significantly improve operating efficiency

Abstract

The invention discloses an automatic operation system of a drilling string. The automatic operation system mainly consists of an automatic catwalk machine, a drilling floor manipulator, a power clip, an iron driller, a power hanging clip, a monkey board pipe arrangement manipulator, a top drive, a winch, a driller integrating control system and the like. The automatic operation system has the advantages that after the automatic operation system is arranged on a petroleum drilling machine, the automatic drilling operations, such as lifting and lowering of the drilling string in the drilling floor, drilling, drill lifting, drill lowering, and stand discharging, are realized; the automation degree of the drilling machine is improved, and the problems of high labor intensity, high risk and low efficiency caused by overhead operation and multi-person matching operation in the existing drilling string operation method are solved; the defects of decreasing of local labor intensity, and failure of reducing of number of operators and improvement of operation efficiency caused by using of one or several automatic devices of the existing drilling machine are overcome.

Description

technical field [0001] The invention relates to the technical field of oil drilling equipment, in particular to an automatic operating system for drilling strings used in oil drilling rigs that is safe, efficient, and low in labor intensity. Background technique [0002] The new technology and equipment of drilling rig automation were mainly used in offshore drilling rigs in the early stage. In recent years, the demand for equipment automation and high safety of land drilling rigs has been increasing. The major oil equipment companies in the world have actively responded to the urgent market demand for drilling equipment and accelerated the automation of land drilling rigs. The research and development of intelligent equipment has continuously launched automatic catwalk machines, power slips, power elevators, iron drillers, drill floor and second-floor platform pipe string automatic discharge devices, and driller integrated control systems. At present, the research and devel...
