摘要
根据流体包裹体的透光和荧光性特征,首先将包裹体划分为烃包裹体、含烃包裹体和无荧光的盐水包裹体与非烃包裹体3大类。其次,再根据包裹体的组成和相态特征,将烃包裹体划分为以下9类:液态烃-气液烃包裹体、气态烃包裹体、含沥青包裹体、含烃盐水包裹体、含烃气体包裹体、液相盐水包裹体、两相盐水包裹体、非烃气体包裹体和含子矿物的盐水包裹体。液态烃-气液烃包裹体类进一步划分为以下4个亚类:重质油包裹体、中质油包裹体、轻质油包裹体和凝析油包裹体。论文还重点探讨了烃包裹体在烃源岩、储集岩和输导岩中的分布规律及各类流体包裹体在油气生成、运移和成藏演化中的地质应用。
Abstract
This paper presents a systematic nomenclature and taxonomy for fluid inclusions.Three groups of inclusions,namely the hydrocarbon inclusions,hydrocarbon-containing inclusions,and aqueous/non-hydrocarbon inclusions ,have been recognized based on microscopic fluorescence and transmitted light properties of inclusions.The hydrocarbon inclusions can be further divided into nine types based on their composition and phase characteristics :liquid hydrocarbon-liquid-gaseous hydrocarbon inclusions,gaseous hydrocarbon inclusions,bitumen-containing inclusions,hydrocarbon-bearing aqueous inclusions,hydrocarbon-bearing gaseous inclusions,liquid phase aqueous inclusions,two-phase aqueous inclusions,non-hydrocarbon gaseous inclusions,and childmineral-bearing aqueous inclusions.The liquid hydrocarbon-liquid-gaseous hydrocarbon inclusions can also be divided into four subclasses:heavy-oil inclusions,medium-oil inclusions,light-oil inclusions,and condensed oil inclusions.In addition,the paper also focuses on the distribution patterns of hydrocarbon inclusion in reservoirs, source rocks,and carrier beds,and the geological application of these fluid inclusions to the generation,migration,accumulation,and evolution of hydrocarbon.
