[Elementary investigation on the application of laser Raman microprobe in petroleum exploration]

Laser Raman Microprobe (LRM) is a micro-analytical technique for determining molecular components. Based on the summarization of the applications of LRM in petroleum exploration, the authors analyzed fluid inclusions (FI) and organic matters, and found that this technique could not only research qualitatively different phase components of single fluid inclusions and the types of organic substances, but also determine quantitatively each phase component of single fluid inclusions and the indexes of maturation of vitrinite. It is concluded that it is feasible to calculate the salinity of single FI by to sigmaB % NaCl = 61.183S - 22.173 and the reflectance (R0) of vitrinite by R0 (%) = 0.69 ln(82.12 D - 16,054.49) - 4.88.
