Abstract

The invention discloses a Kelly board tubular column arrangement system and an operation method thereof. The system comprises a longitudinal shift assembly, a mechanical hand assembly, a mechanical arm assembly, a pulley assembly, a walking board assembly, a Kelly board tube bent frame; one end of the mechanical arm assembly is connected with the mechanical hand assembly, the other end of the mechanical arm assembly is connected with the pulley assembly; the mechanical hand assembly is driven by hydraulic pressure and internally provided with a plunger cylinder, and tong dies are fixed on a clamping part, the mechanical hand assembly is further provided with a contact-type displacement transducer; a low-speed huge-torque hydraulic motor is arranged at the top of the pulley assembly and connected with the mechanical arm assembly by a driving flange to drive the mechanical arm assembly to rotate, running pulley sets are arranged at the two sides of the pulley assembly; the longitudinal shift assembly is fixed to the pulley assembly by a ball-screw screw nut; the walking board assembly is arranged above the longitudinal shift assembly; the Kelly board tube bent frame is arranged above the walking board assembly.The invention can simplify mechanical construction in the process of realizing arrangement automation of Kelly board tubular columns, thereby lowering equipment cost and maintenance cost.

Description

technical field [0001] The invention relates to the technical field of petroleum and natural gas exploitation, in particular to a pipe string discharge system for a two-story platform and a working method thereof. Background technique [0002] Today's oil and gas industry pays more and more attention to HSE (Health, Safety and Environment), especially in the field of drilling and workover with harsh working conditions. Gradually reducing the labor intensity of workers, improving operation efficiency and ensuring construction safety have become the main tasks in the future. development trend. [0003] At present, the pipe string discharge operations of the existing drilling rigs and workover rigs are all completed by drillers on the second-floor platform. The working conditions are difficult, the safety is not guaranteed, the operation efficiency is low, and it may not be possible under severe weather conditions. However, on domestic drilling rigs or workover rigs, the devel...
