ELECTRONIC DOWNHOLW DEVICE OF TELEMETERING SYSTEM Russian patent published in 2009 - IPC E21B47/00 H01R24/14

Abstract RU 2371574 C2

FIELD: oil-and-gas production.

SUBSTANCE: electronic downhole device consists of separate blocks. Running gear is implemented in the form of cylinder with milling from both sides lengthwise axis, on which there are installed circuit boards, connected to each other by pin connector. Connector assemblies are implemented in the form of profiled L-shaped projections, on which there are installed pin connectors, providing electric coupling between circuit boards of adjacent blocks, and reciprocal surfaces with ability of providing of axial and circumferential fixation of blocks. On cylindrical sections running gear there are implemented annular grooves for installation of damper ring.

EFFECT: reliability enhancement of structure and reduction of labour coefficient of manufacturing and repair of electronic downhole device.
