摘要：

有机包裹体是烃类生成、演化、运移和聚集的直接标志。本文研究了川东地区下三叠统嘉陵江组第二段(T1j2)在不同成岩阶段的有机包裹体特征,确定了天然气运移的时期、深度、方向、通道和相态、气源等,通过典型实例提出了天然气成藏远景评价的五项包裹体标志。这是油气运移研究中的一项新技术,初步证明有较好的效果。

Abstract:

Organic enclosure is the direct indicator of hydrocarbon generation, migration, accumulation and evolution. This paper discussed the properties of organic enclosures in different diagenesis stages from the Second Member of the Lower Triassic Jialingjiang Formation and determined the time, depth, direction, passage, phase state of migration and source of the gas. Five indicators, namely the type, amount, temperature, paleosalinity and constituent of the organic enclosures for the pool-forming assessment of natural gas pools are proposed based on typic dissection and contrast. Studying gas migration with organic enclosures, a comprehensive dynamic research in connection time with space could be made and the examinational results of Huangcaoxia gas pools are pretty well.
