摘要
激光扫描共聚焦显微镜(CSLM)被应用于石油地质学各方面的研究目前仍处于探索之中,为了更有效开发该仪器的功能应用于石油地质学领域,本文以东海盆地西湖凹陷秋月一井致密砂岩储层岩石薄片为例,应用CSLM观察和计算了孔喉直径、结构、形态和油气赋存状况,同时改进了孔隙度计算方法,提高了精度;以塔里木盆地顺904井志留系储层流体包裹体薄片为例,改进了测量油包裹体的气液比的方法,减少了油包裹体的荧光遮盖效应,提高了精度,并结合热动力模拟软件恢复了古压力值。
The applications of Confocal Scanning Laser Microscopy（CSLM） in petroleum geology are still under developing. In order to effectively develop the function of the equipment in the petroleum geology,the concrete application examples of CSLM about pore throat characterization in reservoir and fluid inclusions were demonstrated in this paper. Taking rock thin section of tight sandstone reservoir in QY1 well in Xihu sag,East China Sea Basin as an example,the pore diameter,fabric,morphology and hydrocarbon existence state were calculated and observed by CSLM. At the same time,the porosity calculation method was improved,so the precision was improved. Taking fluid inclusion slice of silurian reservoir of 904 well in Tarim Basin as an example,the measurement method of gas liquid ratio of oil inclusions was improved by reducing the fluorescence cover effect of oil inclusions to improve the precision. The paleo pressure value was restored by thermodynamic simulation software.
