Inclinometry positioning system for drilling of drilling machine

Abstract

The invention relates to the technical field of oil exploitation, and discloses an inclinometry positioning system for drilling of a drilling machine. The inclinometry positioning system comprises a fixed sleeve, fixed blocks are fixedly mounted at the bottom end of the fixed sleeve at equal angles, upper movable rods are arranged below the fixed blocks, lower movable rods are arranged below the upper movable rods, and the upper movable rods and the lower movable rods are rotatably connected. According to the inclinometry positioning system for drilling of the drilling machine, a drill bit can be led into the ground through a through groove during use, the drill bit can make contact with the upper movable rods or the lower movable rods when continuing to descend and incline, and when the upper movable rods rotate relative to the lower movable rods, at the moment, pressure can be applied to movable plates to drive movable columns at the bottom ends of the movable plates to move relative to fixed columns and drive buffer springs to be compressed, the movable plates can move relative to the whole fixed sleeve, and the moving distance of the movable plates can indicate the deviation angle of the drill bit. Therefore, the advantage that the inclination angle of the drill bit can be indicated is achieved.

Description

technical field [0001] The invention relates to the technical field of oil exploitation, in particular to an inclinometer positioning system for drilling with a drilling rig. Background technique [0002] A drilling rig is a complex set of machines, which consists of machines, units and mechanisms. A drilling rig is a mechanical device that drives a drilling tool to drill underground to obtain physical geological data during exploration or mineral resource development (including solid ore, liquid ore, gas ore, etc.). Also known as drilling machine. The main function is to drive the drilling tool to break the rock at the bottom of the hole, and to lower or lift the drilling tool in the hole. It can be used to drill cores, ore cores, cuttings, gaseous samples, liquid samples, etc., to ascertain the conditions of underground geology and mineral resources. The working principle of the drilling rig is generally that the ring and the ring seat are connected by a pin shaft, the ...

AI Technical Summary

Problems solved by technology

[0003] During the drilling process of the drilling rig, the distance drilled by the drill bit into the ground is generally as many as several hundred meters. The inclination phenomenon of the drill bit inevitably occurs during the extraction process. In the prior art, it is generally found that when the drill bit inclines, the drilling rig will be stopped to make it rise and then continue to descend and drill again. At the same time, the existing technology cannot correct the inclination of the drill bit. Instructions are extremely inconvenient to use

[0004] During the drilling process of the drilling rig, when the operator finds that the drilling of the drill bit is tilted, the drill bit is usually stopped immediately, and the rise of the drill bit is controlled, and the drill bit is drilled into the ground again after adjusting the angle of the drill bit. When there are multiple inclinations during the drilling process, it is necessary to repeat this step and adjust it several times. In the prior art, it is impossible to quickly adjust the inclination angle of the drill bit, resulting in low work efficiency during the drilling process.
