| Abstract: | Mass spectrometry and chromatography were used in the on-line and in situ analysis of fluids in the Chinese continental scientific drilling project. The drilling processes and mud have great effects on the identification of fluids. After considering the effects of air components and artefacts on the deep fluids, we have found that in some segments, helium, methane and carbon dioxide are the main gas components that should originate from the deep Earth. The correlations among gas components are discussed and the fluid profiles in the hole are presented. |
