INCLINOMETER Russian patent published in 2005 - IPC

FIELD: exploration drilling, particularly to determine curvature of expendable wells.

SUBSTANCE: inclinometer comprises body with spherical inner surface, elastic diaphragm with extension and arrestment device. Body is filled with inert liquid and ball-shaped float is arranged inside the body. Ball-shaped float is provided with spatial orientation means. Pole points of ball-like float are provided with projections defining gap between mated sphere surfaces. Equatorial float plane is provided with ring defining gap between spherical surfaces of the body and the float.

EFFECT: increased accuracy of well curvature determination and reduced inaccuracy of well zenith and azimuth angle measurements.
