ELECTRONIC MODULE OF TELEMETER DOWNHOLE DEVICE Russian patent published in 2009 - IPC E21B47/01 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to directed drilling equipment, namely to measuring equipment retentions in hermetic enclosure of electronic module of downhole device. The offered electronic module of downhole device contains the enclosure cross-armed in electric divider, radiator with upper end face containing electrical connection to generator, dampers between which there is chassis mounted with electronic components and inclinometer sensors peripheral deposition proof, plug fitting hermetically closing the enclosure from below. Herewith the lower damper contains the puller axially moving in rebore of the plug fitting and radial motion proof by pins. Axial position of the puller is regulated by the screw coaxial to the plug fitting in the hole formed wherein. The hole in the plug fitting is stepped with threaded and cylindrical segments. Cylindrical segment of the hole and the screw are sealed from each other with sealing rings. Threaded segment of the screw is of greater diameter, than cylindrical, and on its end face it contains screwdriver slot from the cylindrical segment. The lower and upper dampers are radial motion proof on the chassis by the pin. The plug fitting is provided with collar over which the plug fitting is pressed to the enclosure end face of the electronic module with sleeve nut.

EFFECT: higher efficiency and reliability of measuring equipment performance and higher overall damper performance due to reduced vibrations ensured by axial fix force control of the enclosure chassis.
