High-integration-level modular power catwalk base convenient to move and transport rapidly

Abstract

The invention discloses a high-integration-level modular power catwalk base convenient to move and transport rapidly. The high-integration-level modular power catwalk base comprises two symmetrically-distributed frame bodies, wherein a ramp and a support are hinged between the two frame bodies; a drill string feeding mechanism is hinged to the upper end of the ramp; the upper end of the support isarranged in the drill string feeding mechanism in a sliding mode; two rows of pipe racks are hinged to the outer side of each frame body; a lifting mechanism is arranged at the end of each pipe rack;supporting legs are arranged below the lifting mechanisms; an electric control system, an operation table, a plurality of reciprocating driving mechanisms and a plurality of inclining mechanisms in lap joint with the pipe racks are arranged in each frame body; a stop pin is arranged on the upper part of each inclining mechanism; a lifter is arranged on the lower part of each inclining mechanism;and the driving end of each reciprocating driving mechanism is connected with the corresponding pipe rack. According to the power catwalk base, the moving and transporting capacity and the working efficiency of a power catwalk are improved.

Description

technical field [0001] The invention belongs to the technical field of oil drilling and production equipment, and in particular relates to a highly integrated modular power catwalk base which is convenient for rapid transportation, and also relates to a method for using the base. Background technique [0002] The power catway is one of the important automation equipment in the modern drilling string handling system, which is mainly used to transport the drill string between the ground and the drilling floor. Powered catwalks are usually installed near the wellhead on the drilling floor, and are mainly composed of catwalk bases, drill string delivery devices, ramps, hydraulic systems, power and control systems, rope double-action winches, etc. There are various structural forms: wire rope pulling type, hydraulic cylinder lifting type, horizontal catwalk, workover rig catwalk, etc. [0003] After investigating the power catwalk products used in the oil field, it is found that...

AI Technical Summary

Problems solved by technology

[0003] After investigating the power catwalk products used in the oil field, it is found that the conventional power catwalk bases have the following disadvantages: (1) The catwalk bases of most products are skid-mounted structures, which are difficult to move when moving or moving. It needs the participation of a crane to complete, which is inconvenient to move and has a large workload; (2) The conventional hydraulic catwalk uses a separate hydraulic station or a hydraulic station shared with other devices, so that the base of the catwalk is connected to the hydraulic station of the drilling rig There are a large number of hydraulic valves and pipelines and the layout is chaotic; (3) The non-body layout of the hydraulic station and electric control cabinet makes the connection and debugging of the catwalk base very troublesome in terms of electric control and hydraulic pressure, and the workload of moving, transportation and disassembly is large (4) There are many types of catwalk bases and various forms, which is not convenient for standardization and modularization work
