Marine Geochemistry Rapid Detection Technology And The Applications In The Gas Hydrate Survey

Along with rapid economic development, and increasing conspicuous of energy supply and demand, a new energy resources-natural gas hydrate of enormous potential exploration attains widespread concern, therefore the development of natural gas hydrate exploration technologies is supported as a major research project by the Ministry of Science and Technology of China in the "fifteenth" marine gas hydrates 863 plan. This thesis is studied under this background and relying on the research project, aiming at the marine gas hydrate exploration geochemical scene urgent samples and the high-precision processing technology, high-sensitivity analysis and testing research, the paper itself is part of the contents of research projects.The major research paper says : prospecting for marine gas hydrate resources to the pressing needs of geochemical exploration techniques, and there is no convenient supporting domestic ship geochemical exploration techniques rapid survey of the current status, the marine gas hydrate resources geochemical rapid detection system research and development.Mainly include:1, developed "the whole operation produced portable device". The equipment used for the collection of seabed sediments, water samples processing, or can also order from the samples away dissociate, hot-and-sour type of hydrocarbon gas samples for analysis gas transmission test equipment.2, developed a high-sensitivity sensors for high-precision technology core "gaseous hydrocarbon sensor testing device", the equipment can also measure multiple parameters gaseous hydrocarbon micro trails content measurement accuracy can reach 10^-11grade.3, complete the two pilot districts gas hydrates resource surveys of South China Sea waters near Xisha Island and southeast Hainan.Technical characteristics of the system are : machines with the convenience, easy operation, good stability, which can be adapted to inclement sea conditions;Geochemical indicators and parameters of the site survey and analysis of data processing, interpretation evaluation.Through two tests of oversea to prove that the system of on-site real-time can rapidly extract hydro carbon gas from seabed sediments, water samples of various types, high sensitivity and high-precision measurements of the gaseous hydrocarbon micro category winners trails content, the rapid completion of the discovery of gas hydrates resources with the geochemical anomalies and initial evaluation of thegeological interpretation of the mandate.The technical fill our waters ship geochemical rapid detection technology gaps, complement our comprehensive exploration of marine gas hydrate resources technical series, the overall technology research with originality, the flow of hardware and software integration and functional characteristics.
