METHOD AND SYSTEM FOR EXTRACTING, ANALYSING AND MEASURING CONSTITUENTS TRANSPORTED BY A BORE FLUID

摘要

The invention concerns a method and a system for extracting, analysing and measuring constituents carried by a bore fluid during drilling operations. The system comprises in combination: means for sampling (4) a volume of fluid, means for extracting (3) in vapour form the constituents contained in the fluid including a low pressure space, a transport conduit (14), sampling means (27) comprising a sampling loop enabling to sample a predetermined amount of vapours circulating in the conduit, dispensing means (40) injecting the amount into analysing and measuring means (31), means for controlling the temperature (33) of the sampling means to avoid condensation of said amount of vapours.
