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(T_j_2)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。
Organic enclosure is the direct indicator of hydrocarbon generation, migration, accu-mulation and evolution. This paper discussed the properties of organic enclosures in differ-ent diagenesis stages from the Second Member of the Lower Triassic Jialingjiang Forma-tion and determined the time, depth, direction, passage, phase state of migration and sourceof the gas. Five indicators, namely the type, amount, temperature, paleosalinity andconstituent of the organic enclosures for the pool-forming assessment of natural gas poolsare proposed based on typic dissection and contrast. Studying gas migration with organicenclosures, a comprehensive dynamic research in connection time with space could bemade and the examinational results of Huangcaoxia gas pools are pretty well.
