【摘要】 江汉盐湖盆地下第三系潜江组和新沟咀组包裹体可划分为8期7种类型,主要为液体包裹体,包裹体一般为10~30μm,均一温度为35~120℃,含盐度为0~35 wt%,烃类包裹体占30%。有机包裹体研究表明,区内烃源岩演化程度低,有机质处于未成熟—成熟阶段;不同产状(期次)孔隙充填矿物中的流体包裹体特征研究表明,石油生成和初次运移发生于早第三纪末及其以后,石油大规模运移聚集发生于晚第三纪中晚期。更多还原

【Abstract】 Inclusion enclave of both Qianjiang Formation and Xingouzui Formation in Jianghan salt lake basin of lower Tertiary system may be divided into 8 stages and 7 types,dominantly being fluid inclusion enclave with 10-30 μm,homogeneous temperature of 35-120℃,salt content of 0-35wt%,and hydrocarbon inclusion enclave occupies 30%.Research on organic inclusion enclave indicates that,hydrocarbon evolution degree is low for the region with organic material at immature-mature stage.Features of fluid inclusion enclave of guest mineral in pores of different occurrences(phases) shows that,oil generation and original migration occurred at the end of early Tertiary and later period,and extensive oil migration and accumulation occurred in the middle and later period of later Tertiary.更多还原
