摘要
西藏羌塘盆地是特提斯构造域巨型油气富集带中一个大型晚古生代-中生代海相残留盆地。本文根据羌塘盆地流体包裹体观察和测试资料,对流体包裹体的组合类型和特征进行了系统研究,定量地分析了晚三叠世-中侏罗世海相地层油气运移的期次,研究表明羌塘盆地晚三叠世-中侏罗世海相地层存在三次油气运移期。这为该区的成藏研究提供了重要依据。
Qiangtang Basin is a large residual basin in the Tethys tectonic region formed in late-Paleozoic-Mesozoic. According to the results of field observation and laboratory testing of fluid inclusions in the Qiangtang Basin, the main types and characteristics of fluid inclusions were studied in this paper. The authors discussed quantitatively episodes of hydrocarbon migration in the marine strata from Late Triassic-Mid-Jurassic in the Qiangtang Basin, and determined three episodes of hydrocarbon migrations based on study of inclusion combinations. The study provides an important basis for the research on the reservoir formation of the marine strata in the region.
