Problems solved by technology
The fiber optic gyroscope is used for drilling holes with an aperture smaller than Φ110mm. Since the conventionally used drill pipes are generally Φ50mm and Φ60mm drilling tools, the inner diameter is generally smaller than Φ42mm, which is smaller than the outer diameter of the fiber optic gyroscope. The methods and tools used in conjunction with

Abstract
The invention relates to a clamping device for a fiber optic gyro inclinometer, aiming to provide a clamping device for a fiber optic gyro inclinometer that solves the problem of directional correction in small-diameter drills and is very convenient for disassembly and clamping. device, the clamping device is divided into four parts, the leftmost end of the clamping device is set as a righting handle, the right side of the righting handle is set as a righting tube, and the right side of the righting tube is set as a locking device, the The right end of the keying device is set as a drill rod handle, and the upper part of the keying device is provided with a keyway. The clamping device made by the present invention can firmly combine the drill pipe with an inner diameter smaller than the outer diameter of the fiber optic gyroscope with the fiber optic gyroscope. The directional correction problem of small-diameter drilling can be solved, and a good directional effect can be achieved, and the disassembly and clamping of the fiber optic gyroscope during the work process are very convenient and fast, which greatly improves the flexibility and safety of construction work. It effectively saves the time of construction operation, avoids the waste of manpower and material resources in the process, and has good efficiency.
Description
technical field [0001] The invention relates to the technical field of gyro inclinometers, in particular to a clamping device for an optical fiber gyro inclinometer. Background technique [0002] The inclinometer is an indispensable tool in oil and gas fossil fuel drilling engineering. At present, various types of inclinometers are used in the field, such as photo sheet, multi-point inclinometer, electronic single-multi-point inclinometer, wired inclinometer while drilling and wireless inclinometer while drilling. Wired inclinometers while drilling and wireless inclinometers while drilling are mainly used for directional measurement in directional wells and horizontal wells, and can also be used in vertical wells, but they are rarely used in vertical wells because of their high cost. At present, electronic single-multi-point instruments are widely used to measure the inclination of vertical wells, but they cannot be installed in the drill collar tool, and their anti-vibrati...
