Abstract

Abstract

Researches of gas hydrate involve cross-disciplinary data from geophysics, geochemistry and geology. Geochemical technologies can be used to collect the trace amount geochemical data about gas hydrate from seafloor media which will indicate the abnormal region. The original data was collected in the marine science investigation about gas hydrate in 2000 and 2001. After further indoor analysis and testing of multiple hydrocarbons, the abnormal region of marine gas hydrate was indicated, and the evaluation results were also derived from comparative analysis of seismic BSR and BZ about gas hydrate. With the on-site isotope data, the resulting cause about gas hydrate methane was discussed. These achievements will provide direct geochemical evidences for the exploration of gas hydrate at Xisha ocean trough.
