摘　　要：应用流体包裹体观察和激光拉曼探针等微观技术对临清坳陷东北部的德南洼陷流体包裹体特征及成分、压力等物理化学条件的研究表明，研究区共有6种类型的包裹体：单相盐水包裹体、富液相包裹体、富气相包裹体、含液态CO2三相包裹体、富液态烃有机包裹体、富气态烃有机包裹体，其中富液态烃有机包裹体的均一温度为100-140℃的较多。包裹体的液相成分主要为H2O0和Cl^-，气相成分主要为CO2、CH4以及微量的C2H6等，包裹体成分研究结果表明在古近系和新近系中主要为未成熟一低成熟的液态烃流体活动；在古生界及部分上部层段中主要为成熟、高成熟的气态烃流体活动。根据盐水溶液包裹体的均一温度和冷冻温度计算得出研究区的流体压力为10-95MPa，其中，在烃类流体大量排出运移时期经历过压力由突破到释放的过程；初步评价了区内的油气有利远景区。The paper analyses the characters of fluid inclusions in Denan Sag of Linqing Depression by observing fluid inclusion and Raman spectrum technologies. There are six types of fluid inclusion in Denan Sag,including single phase inclusion,liquid-rich inclusion, gas-rich inclusion, multi-phases with liquid CO2 fluid inclusion, liquid hydrocarbon inclusion and gaseous hydrocarbon inclusion. The best homogeneous temperature section of liquid hydrocarbon inclusion is 100-140 ℃. The fluid is composed of H2O,Cl^-, CO2,CH4 etc,indicating the crudity or low-mature liquid hydrocarbon in Tertiary and the mature or overmature gas hydrocarbon in Paleozoic and up stratum. The fluid pressure is 10-95 MPa by the homogeneous temperature and cold temperature of brine solution inclusion. Generally, the fluid activities are always with pressure breakthroughs. At last, the paper estimates some favourable targets for further exploration.
