摘要
利用流体包裹体在储层中的种类、含量、分布等常规特征以及它们与成岩矿物的结构关系,可以分析油气运移及圈闭充注模式;根据包裹体的均一温度并结合盆地的古地温史和埋藏史,可以确定油气成藏期次。应用显微—红外光谱技术、包裹体的鉴定和均一温度测定技术,分析了松辽盆地中浅层和深层样品的包裹体。同时利用红外光谱的有关参数划分了各井包裹体的油气成藏期次,结果与镜下鉴定结论相一致,并确定了其中油气包裹体的成熟度。同时利用流体包裹体均一温度并结合埋藏史和古地温史,研究了松辽盆地部分地区油气成藏期次。
The general characteristics of fluid inclusions and their type,content,distribution and structure relationship with diagenetic minerals can be used to study the oil and gas migration and trap charging modes. The period of oil and gas accumulation can be determined,according to the homogenization temperature of fluid inclusions and the paleo-temperature history and burial history of the basin. The microscope-infrared spectroscopy (MicroFTIR) technique and the techniques for inclusions determination and homog...
