Description

Technical Field

[0001] This utility model relates to the technical field of measurement while drilling (MSD) probe devices, and in particular to a mining MSD probe device. Background Technology

[0002] Measurement while drilling (MSW) technology is often used in geological exploration. This involves installing MSW equipment behind the drill bit to measure the geological parameters of the formations around the drill bit in real time. This helps identify complex coal seams with industrial mining value and allows the drill bit to stop in the desired reservoir in a timely manner. At the same time, the position of the drill bit, drilling trajectory, well inclination, well diameter, and vibration parameters are monitored to achieve real-time positioning and timely correction.

[0003] As disclosed in application number CN202420040320.9, a drilling trajectory measurement probe includes a measurement probe with a insertion groove at its rear end and a drainage hole at its rear end below the insertion groove. A first flange ring is fixedly installed on the rear end surface of the measurement probe, and a second flange ring is fixedly installed at the rear end of the first flange ring. A drill rod is fixedly installed inside the second flange ring, and a positive electrode seat is fixedly installed at the front end of the drill rod. An arc-shaped water pipe is fixedly connected to the front end of the drill rod directly below the positive electrode seat. This device divides the measurement probe into three areas: an isolated water path area, a detachable positive electrode seat area, and an installation area for the measurement device that can be quickly installed and adjusted.

[0004] However, the above-mentioned device is assembled using flange rings, which increases the outer diameter of the probe. When the probe is lowered, the flange rings are prone to scraping sand and gravel, causing blockages and hindering well operations. Utility Model Content
