西南石油学院、江汉石油学院、四川石油管理局地质勘探开发研究院于1992年开始共同研究激光微取样碳酸盐岩碳、氧同位索分析方法,研制成功的激光微取样同位素分析系统于1994年6月通过中国石油天然气总公司石油勘探开发科学研究院组织的专家鉴定,该系统属国内首创.达国际先进水平。激光微取样同位索分析系纺将Nd:YAG激光器与改装后的显微镜同轴安装,高能量的激光束经显微镜光学系统聚焦(～20μm)在真空样品室内的薄片或薄板碳酸盐岩样品上,以足 Southwest Petroleum Institute, Jianghan Petroleum Institute, Geological Exploration and Development Research Institute of Sichuan Petroleum Administration began in 1992 to jointly study carbon micro-sampling carbonate rock oxygen and oxygen isotope analysis method, the successful development of laser micro-sampling isotope analysis system in 1994 In June, it was appraised by experts organized by China Petroleum Exploration and Production Research Institute of China National Petroleum Corporation, which is the first in China and reached the international advanced level. Laser micro-sampling Homology analysis Spinning a Nd: YAG laser coaxially with a modified microscope, a high-energy laser beam was focused (~ 20 μm) through a microscope optical system onto a thin sheet or thin plate carbonate sample in a vacuum sample chamber To foot
