Description

technical field [0001] The invention belongs to the field of inertial measurement, and relates to an integrated device of inertial measurement components for an inclinometer, which is suitable for a small-scale high-precision drilling inclinometer. Background technique [0002] In drilling measurement, it is required that the measuring instruments used have relatively strict restrictions on the radial dimension: the smaller the casing and drill pipe used in the cased well, the smaller the space left for the measuring instrument, and the smaller the space for the measuring instrument. The smaller the radial size is required; in small curvature wells, especially small curvature wells with casing openings, the axial size of the measuring instrument has the same high requirements and restrictions as the radial size. Therefore, a special structure needs to be used to solve the size limitation problem. [0003] In an inclinometer and orientation system using inertial technology, ...
