WELL BORE DEVIATION ZENITH ANGLE MEASUREMENT DEVICE Russian patent published in 2006 - IPC E21B47/22 G01C9/00 

FIELD: oil and gas industry, namely well drilling, particularly to determine spatial position of well bores under drilling.

SUBSTANCE: device comprises frame made as sealed chamber, which is rotated about supports, power source eccentrically secured in frame and made as compressed air cylinder and jet generator provided with feed nozzle, receiving nozzle, outlet nozzle, profile with streamlined surface and communication channel. The feed nozzle communicates with compressed air cylinder. Jet generator has membrane with contact member fastened to the membrane, as well as pinned sliding hollow plummet. Receiving nozzle is created in upper plummet part so that the receiving nozzle may slide with respect to streamlined surface of the profile and communicated with feed nozzle. The jet generator also has contact rings, information reading contacts and transfer contact. Outlet nozzle is communicated with membrane cavity of the membrane. Contact secured to the membrane is linked to contact rings through transfer contact. The contact rings are permanently linked to information reading contacts connected with communication channel.

EFFECT: increased accuracy and reliability of well bore deviation angle determination, possibility of on-line well bore drilling control to provide well bore drilling along optimal paths.
