METHOD AND DEVICE FOR STABILISATION OF ELECTRON BOARD OF ACCELEROMETERS IN INSTRUMENT CASE OF DOWNHOLE TELEMETERING SYSTEM Russian patent published in 2011 - IPC E21B47/22 E21B47/12 

FIELD: oil and gas production.

SUBSTANCE: invention can be applied in a technology of stabilisation of electron metering components in an instrument case of a downhole telemetering system (DTS). According to a method, at first there is manufactured a small-sized holder on high-precision small-sized machine tools with controlled fabrication of orthogonal planes of equal areas, then electron boards of accelerometers are mounted on these planes of the demountable orthogonal-plane holder. The holder is small-sized with precise orientation of the orthogonal planes. Thus electron boards are precisely oriented on these planes and easily mounted. The holder is pressed to the plane and screwed to a wall of the instrument case. The holes in the demountable orthogonal-plane holder and in the wall of the instrument case are precisely mutually oriented, and screw adjustment in these holes does not disturb arrangement of the electron boards. This ensures precise mounting of the electron boards on a separate carriage that finally improves measurement reliability while the instrument being in service.

EFFECT: simplified technology of sabilisation of the electron boards of the accelerometers to the instrument case of the DTS and higher measurement accuracy of the instruments.
