An overall step-by-step transfer device for a roller-row type omnidirectional drilling rig

Abstract

Provided is a roller row type omni-directional drilling rig whole step-by-step moving device. A support is fixed to a cluster well rig substructure through connecting pin shafts, and a reversing rotating mechanism and a trolley are installed on a skid. The trolley is composed of a tray, an upper trolley base, a roller row and horizontal movement oil cylinders. The roller row is formed by installing 14 rollers on a frame, the horizontal movement oil cylinders are connected with the upper trolley base through pin shafts, piston rods of the horizontal movement oil cylinders are connected with the tray through bolts, guide rolling wheels are installed on the two sides of the front end of the upper trolley base, lug plates are installed at the two ends of the roller row, the roller row is connected with the upper trolley base through an adjusting rod, the trolley is connected with a jacking oil cylinder through a spherical surface tray and a clamping plate set, the jacking oil cylinder is installed on the support through bolts, and the spherical surface tray is installed on the upper trolley base. A limiting ring is installed on the spherical surface tray. Through the roller row type omni-directional drilling rig whole step-by-step moving device, on-site rotation of a whole drilling rig can be achieved, well site adaptability of the moving device is improved, the same moving device can be shared by multiple drilling rigs, and investment is saved.

Description

technical field [0001] The invention belongs to the field of oilfield drilling and repairing machines, and in particular relates to a step-by-step transfer device for the whole drilling machine. Background technique [0002] According to the needs of oil and gas field development, on offshore drilling platforms and specific areas of land oilfields, oil drilling rigs need to use close-distance network or linear multi-well cluster well drilling operations. This operation mode requires the drilling rig to move as a whole. [0003] The overall step-by-step transfer device of the all-round drilling and repairing machine uses the jacking cylinder to lift the drilling rig as a whole, and then uses the translation cylinder to push and pull the device for step-by-step translation, which can realize the overall omnidirectional translation of the drilling rig, and has a small area on the well site It is highly applicable in the drilling operation of cluster wells with arbitrary arrange...

Problems solved by technology

[0006] The purpose of the present invention is to overcome the shortcomings of the existing step-by-step transfer device for drilling rigs, such as the limited movement direction and the inability to achieve precise movement, etc., to provide a step-by-step transfer device that can accurately realize the overall drilling rig in an all-round way, and has a simple structure. It is easy to use, and can realize the rotation of the whole drilling rig, so that the drilling rig equipment can be shifted and reversed without disassembly, and the overall movement between wells with multiple well positions can be realized, which can meet the needs of small area and irregular well site conditions. need
