    • PROBLEM TO BE SOLVED: To measure the composition of isotopes in a specimen in real time. SOLUTION: A method for measuring the composition of isotopes in a fluid in a geological layer includes steps for: (a) introducing a reference fluid having a known isotope composition into a reference cell; (b) acquiring the specimen of the geological layer; (c) preparing at least one laser beam; (d) scaling at least one parameter of the reference cell; (e) causing a beam to pass through the reference fluid to measure the reference measuring beam before and after passing through the reference fluid; and (f) causing a beam to pass through the specimen to measure the beam before and after passing through the specimen to calculate a first isotope concentration from measured values thus acquired. From the measured values, information is acquired as to carbon isotope compositions of individual compounds in a gaseous hydrocarbon mixture. Methane, ethane, propane, isobutane or n-butane, isopentane or n-pentane, etc. can be listed as compounds of this kind. COPYRIGHT: (C)2005,JPO&NCIPI
    • 要解决的问题:实时测量样品中同位素的组成。 解决方案:用于测量地质层中的流体中的同位素组成的方法包括以下步骤:(a)将具有已知同位素组成的参考流体引入参考池; (b)获取地质层样本; (c)制备至少一个激光束; (d)缩放参考单元的至少一个参数; (e)使光束通过参考流体以在通过参考流体之前和之后测量参考测量光束; 和(f)使光束通过样品以在通过样品之前和之后测量光束,以从由此获得的测量值计算第一同位素浓度。 根据测量值,获得关于气态烃混合物中单个化合物的碳同位素组成的信息。 甲烷,乙烷,丙烷,异丁烷或正丁烷,异戊烷或正戊烷等可列为这类化合物。 版权所有(C)2005,JPO&NCIPI
