摘要:
实时甲烷碳同位素录井是一种现场连续、实时检测钻井液中甲烷碳同位素含量的录井技术。根据现场甲烷碳同位素的测定分析，可快速提供有关天然气成因、类型、烃源岩成熟度等多方面信息，并为气、油源对比、多井对比、断层封闭性研究提供重要依据。结合甲烷碳同位素数据，在快速得出储层天然气的成因、类型、烃源岩成熟度的基础上，还对断层封闭研究和油气运移做出分析验证。
The real-time methane carbon isotope logging was a technology for continuous and real-time detecting the methane carbon isotope in drilling fluid. Based on the field methane carbon isotope detection and analysis, the data including the gas genesis, its type and the source rock maturity and etc could be quickly supplied, also an important basis could be provided for gas and oil source contrast, multi-layer contrast and fault sealing ability study. Combined with the data of methane carbon isotope, on the basis of quickly obtaining the data of natural gas genesis, its type, the source rock maturity, also the study of fault sealing ability and hydrocarbon migration are analyzed and proven.
