原始丰度 meaning in English
primordial abundance
Examples
- On the basis of above experiments , the chemical kinetic model inwhich organic matter of source rock of deep - formation in the north of songliao basin primarily crack into oil or gas is established , which set up a basis for evaluating oil - generating amount , gas - generating amount of source rock of deep formation in different periods ; set up the chemical kinetic model inwhich different qualities of oil and family constituents in oil secondarily cracked into gas , which provide theoretical foundation and practical methods for dynamic evaluation of gas - generating amount and oil - consuming amount in process of oil cracking . the geochemical features of source rocks in deep - formation of basins are systematically evaluated
在上述实验基础上，建立了松辽盆地北部深层源岩有机质初次裂解成油、成气的化学动力学模型，为评价深层源岩于不同时期的生油量、生气量奠定了基础；建立了不同性质原油及原油中各族组分二次裂解成气的化学动力学模型，为动态评价油裂解过程的成气量和耗油量提供了理论依据和实用方法；对盆地深层源岩的地化特征进行了系统评价；考虑到深层源岩的成熟度较高，实测地化指标(残余有机碳、氢指数等)不能客观反映源岩有机质的原始丰度和原始生烃潜力。 - Considered that the maturity of deep - formation source rocks is relative high and the practical tested geochemical index ( remnant organic carbon , hydrogen index etc ) can not objectively reflect the original abundance and original hydrocarbon - generating potential of organic matter in source rocks , original hydrocarbon - generating potential and original organic carbon of organic matter are restored from progressive recurrence using chemical kenetic models to calculate hydrocarbon - generating rate in this paper
本文利用化学动力学模型计算的生烃率，建立并实现了通过逐步递推来恢复有机质的原始生烃潜力和原始有机碳。研究结果表明，松辽盆地北部深层恢复后的生烃潜力可达到恢复前的46倍，原始丰度可达到恢复前的2 . 2倍。
