sistema e mÉtodo de extraÇço, de anÁlise e de mediÇço em constituintes transportados por um fluido de perfuraÇço

The present invention relates to an extraction, analysis and measuring method and system intended for constituents carried along by a well fluid during drilling operations. The system comprises in combination: draw-off means (4) for taking a volume of the fluid, extraction means (3) for extracting in vapour form the constituents contained in the fluid, comprising a space placed under underpressure, a transport line (14), sampling means (27) comprising a sampling loop allowing to take a determined amount of the vapors circulating in the line, distribution means (40) that inject the amount into analysis and measuring means (31), control means (33) for controlling the temperature of the sampling means so as to prevent condensation of said amount of vapors.
