A Geological Drill Pipe Feed Depth Measurement System Based on Aberration Analysis of Drill Pipe Nodes

Abstract

The invention relates to a geological drill pipe feeding depth measurement system based on aberration analysis drill pipe nodes, which includes an LED lamp, an image processing module, a component connection module and a surface fixing module; the LED lamp is packaged in a cylindrical shell and the system Outside; the image processing module is packaged in a cylindrical shell and aligned with the surface of the drill pipe, and the camera is used to continuously take pictures at the exit of the drill pipe to complete the aberration analysis and automatic counting of the nodes at the joint of the drill pipe; the parts are connected The module is connected to the LED lamp housing and the image processing module housing; the ground surface fixing module is connected to the LED lamp housing and is suspended and fixed at the outer end of the ground surface and aligned horizontally to the drill pipe; for the process of exiting the drill pipe, the node shape at the joint of the drill pipe is analyzed by aberration Count the number of drill pipes exiting the hole; the length of the drill pipe exit is equivalent to the depth of the drill pipe feed, avoiding the interference of factors such as complex geological environment, irregular operations, water flow and dust, and improving the accuracy of geological information acquisition.

Description

technical field [0001] The invention relates to the technical field of geological equipment detection, in particular to a geological drill pipe feeding depth measurement system based on aberration analysis of drill pipe joints. Background technique [0002] Geological drilling exploration is an effective way to obtain geological information. The drilling depth of drilling rigs is directly related to the quality of exploration, and its real-time measurement is of great significance. The length of the drill pipe of the geological drilling rig is a standard size, the middle is a cavity structure, and the head and tail are respectively provided with a threaded male end and a female end. The two drill pipes can be threaded through the power of the drilling rig. The metal cross-sectional area of ​​the threaded joint is larger than the standard Other rod body parts of the drill pipe constitute the drill pipe node. The drilling rig clamps one drill pipe at a time, and the clamped d...

Problems solved by technology

However, when the geological drilling rig continues to drill or retreat continuously, this technology cannot accurately identify the periodic jumps mentioned above, and there is a hidden danger of data falsification caused by artificially simulating the periodic drilling process
