摘　　要：在对川西地区成岩作用深入研究的基础上,应用激光拉曼探针、显微冷热台和荧光显微分析等技术,对有机流体包裹体的物理相态、化学组成、均一温度和盐度进行了观察和测试。通过对测试结果的对比分析,并结合区域埋藏史研究,将该地区须家河组储层中流体包裹体划分为4个形成期次,并以其为依据,对须家河组的油气运移和演化特征进行了探讨。同时指出了沙溪庙组的高温、高盐度有机包裹体的形成是由于下部流体的跨层涌入所致。Based on the deep research of diagenesis in the west Sichuan, the authors applied Laser Roman Microspectrometer, micro-thermometer and micro-fluorescence analysis technology to observe and test the physical facies patterns, composition, homogenization temperature and salinity of fluid inclusion respectively. Through analysis of the results of test, integrated with burial history, the formation of inclusions was divided into four stages. Finally, the authors discussed the characteristics of migration and evolvement of oil and gas that formed in different stages in this area .
