Downhole sampling tool and method |
摘要 |
A sampling device for use downhole is provided comprising a hollow body (24) having a fluid inlet port (26) for fluid entry to the interior thereof, characterised by a gas extraction system (64) associated with the hollow body (24) and capable of securing as a non-volatile component at least part of a volatile component dissolved in a fluid entering the hollow body (24), the gas extraction system being removable therefrom to allow quantitative analysis of the non-volatile component to be undertaken. The gas extraction system (64) is placed in a supplementary chamber (46) having an inlet (50) and an outlet (52) which is attached to the hollow body and through which fluid passes to enter the hollow body. The gas extraction system is iron oxide to fix sulphur from volatile hydrogen sulphide for later analysis.
