松辽盆地北部自生矿物包裹体研究及应用

^ENCLOSURE OF AUTHIGENIC MINERAL FROM NORTHERN PAPT OF SONGLIAO BASIN AND ITS APPLICATION

本文通过对松辽盆地北部深层石英一方解石脉和砂岩中自生石英包裹体均一温度、盐度及荧光显微镜分析，研究探讨了有机包裹体烃类的生成和运移方向，推算出朝阳沟地区古今温度与深度关系以及大庆长垣以西地区生油门限深度及液态烃勘探下限深度。

Based on analyses of fluorescent microscope and the uniform temperature and salinity of enclo-sure of authigenic quartz frorn quartz-calclte range and sandstone in deep Songliao basin,this paper studies hydrocarbon generation of organic enclostire and migration direction,and calculates the relationship of pale-otemperature and presents temperature with depth in Chaoyanggou area and Oil window depth as well as cut off depth of liquid bydrocarbon in the western part of Daqing Placanticline.
