摘要: 地层油气的性质千差万别。从油气生成、油气运移、油气成藏期作用各阶段机理上分析了地层油气性质产生差别的主要原因。沉积有机质类型和油气生成过程是产生油气性质差别的主要原因, 差异聚集和重力分异作用是产生油气性质差别的第二个原因, 后期的扩散和氧化作用是地层原油稠化的主要原因。

关键词: 油气性质, 油气生成, 重力分异, 扩散, 氧化

Abstract: There are lots of differences for in-place oil and gas property. The main reasons for these differences are analyzed in terms of mechanisms of hydrocarbon generation, migration and accumulation. The first reason for that is the type of depositional organic matter and process of hydrocarbon generation; the second one is the differential gathering and gravitational differentiation. The post-diffusion and-oxidation is the major cause of densification of in-place oil.

Key words: petroleum property, hydrocarbon generation, gravitational differentiation, diffusion, oxidation
