摘要

西藏羌塘盆地为我国陆上油气资源潜力巨大的一个中生代海相残留盆地,火山喷发频繁,尤以中生代为甚。曲色组烃源岩为一套海相的沉积岩系，岩性为油页岩、页岩及灰岩。样品取自南羌塘盆地毕洛错附近与火山岩互层的曲色组烃源岩。该套烃源岩与其周围的玄武岩为同期的不同产物，烃源岩是在早侏罗世形成的，火山岩也是早侏罗世形成的。利用TOC、热解、抽提、GC、GC-MS等地球化学分析技术，对该套烃源岩生烃潜力进行了初步评价，并讨论了该套烃源岩的沉积环境、母源特征及火山活动对烃源岩的影响。分析显示：该套烃源岩有机质丰度较高，有机质类型以Ⅱ型为主，有机质热演化阶段处于成熟阶段；该套烃源岩沉积于强还原—弱还原水体环境，母质来源具有水生生物的输入特征，表现出火山岩浆活动对烃源岩的烘烤作用不明显；综合评价认为这套烃源岩具有较好的生烃潜力。

Abstract

The Qiangtang Basin in Tibet is a Mesozoic marine residual basin with huge potential for oil and gas resources in China.Volcanic eruption was frequent,especially in the Mesozoic.The source rocks in Quse Formation are deposited in marine environment,which are composed of oil shale,shale and limestone.The source rocks of Quse Formation in the study area near the Bijiang fault in the southern Qiangtang Basin are interbedded with volcanic rock.The source rocks and their surrounding basalts are different products in the same period.The source rocks were formed in the Early Jurassic,and volcanic rocks formed in the Early Jurassic.The hydrocarbon generated potential and biomarker composition of source rocks in Quse Formation are investigated using the conventional geochemical methods to discuss the sedimentary environment,the organic matter source and the influence of the volcanic activity on the source rock.The result shows that the organic matter abundance of source rocks is high,and the organic matter is mainly Type II.The bake effect of volcanic magma activity on the source rock is not obvious,the thermal evolution stage of organic matter is in the mature stage.The source rocks are deposited in reduced environment with the contributions of aquatic organisms.The comprehensive investigation indicates that the source rocks in the study area have good hydrocarbon generating potential.
