Abstract:
An extraction, analysis and measuring system intended for constituents carried along by a well fluid during drilling operations, characterized in that it comprises in combination:draw-off means (4) for taking a determined volume of said fluid, extraction means (3) for extracting in vapour form said constituents contained in said volume of fluid, comprising a space placed under underpressure, a vapour transport line (14) whose first end communicates with said space, the second end being connected to a vacuum pump (21), sampling means (27) placed in the vicinity of the second end, comprising a sampling loop (53) allowing to sample a determined amount of the vapours circulating in said line, distribution means (50) for injecting said amount into analysis and measuring means (31), and control means (33) for controlling the temperature of said sampling means so as to prevent condensation of said amount of vapours.
