Downhole steam sampler |
摘要 |
A downhole steam sampler for collecting the liquid phase content of a steam flow, immediately prior to the latter being injected into a substrate surrounding a hole or well. A reservoir within the sampler separates and retains the liquid phase while permitting the vaporous phase to pass. Detent means cooperates with a pair of spaced apart flow control valves to permit said valves to be closed simultaneously when the steam sampling operation is completed.
