Drilling module drill pipe ramp for offshore cluster wells

Abstract

The invention discloses a drilling module drill pipe ramp for offshore cluster wells. The drilling module drill pipe ramp comprises a steel structure frame, a support lug plate is fixedly connected to the front side of the steel structure frame, and a front rolling bar and a rear rolling bar are arranged at the top end of the steel structure frame; the support lug plate is hinged to the front of a ramp body through a support rod, and the tail end of the ramp body is hinged to a drill table through the connecting lug plate; the front rolling bar and the rear rolling bar are located below the ramp body; the ramp body is provided with a guardrail, a ladder and footboards of the ladder penetratingly from front to back, and a safety guardrail, a drill pipe basket and an oblique rack are mounted in the ramp body from front to back. The ramp can adapt to longitudinal and transverse multi-well-site operation and meets the requirement of conveying drill tools of different length specifications, integration and applicability of equipment are improved, equipment purchase cost and drilling operation cost are lowered, and operation efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and relates to a drill pipe ramp for marine cluster well drilling modules. Background technique [0002] The drill pipe ramp is an important equipment of the offshore drilling module, and it is the passage of the drilling tools (including drill pipes, drill collars, casings and other special tools) to the drill floor. Usually the drilling tools cannot be transported in place at one time, and the drill pipe ramp allows the drilling tools to stay on the ramp for a short time. [0003] During the drilling operation of marine cluster wells, the drilling module needs to slide in both vertical and horizontal directions. When longitudinal sliding occurs, the drill floor moves and the solids control system module is fixed, and the length and angle of the drill pipe ramp connected between the drill floor and the solids control system module structure change, and the drill pipe ramp needs to ...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a drilling pipe ramp for marine cluster well drilling modules, which solves the problem that the ramps of the same specification in the prior art are difficult to meet the drilling operation requirements of different well positions and different length drilling tools; The ramp not only increases the total weight of the equipment and the direct cost of equipment manufacturing, but also increases the indirect costs such as drilling time due to the removal and replacement of the drill pipe ramp during the drilling operation
