摘要
本文实验内容包括Au、Ag元素在低熟高硫原油及其共存的水溶液中的分配特征,水-油-岩(矿)反应体系中Au、Ag活化和迁移的能力,以及在共同源岩和温度,压力共同作用的压力机系统中,石油生成和初次运移过程对Au的富集能力等。结果证明,在一定的成熟度范围内R0<0.900%)原油可能成为Au、Ag运移和富集的重要载体以及成矿流体的重要组成部分。
This paper deals mainly with (1)partition of Au and Ag in coexisting phases of lower maturity and high sulphur crude oil and aqueous solution;(2)mobilization and transport abilities of Au and Ag during the interaction of water,oil,and rock (ore);(3)enrichment ability of Au by crude oil during oil generation and primary migration within double source system and under the experimental temperature and pressure.Under the condition of R0≤0.90%,crude oil might become potential carriers of Au during transport, and also become an important part of forming-ore fluids.
