Abstract

The paper describes a process of crude oil differentiation in an oil reservoir induced by an inflow of light hydrocarbons. It was shown that when an oil-rich carbonate rock is destabilized the redistribution of oil components occurs due to the adsorption and/or precipitation of asphaltenes on the rock and their gravitational separation. More compact asphaltene aggregates concentrate in the bottom of the oil reservoirs model.

非平衡储层状态建模中沥青质的再分布

摘要

该论文描述了由轻烃流入引起的油藏中原油分异的过程。结果表明,当富含石油的碳酸盐岩不稳定时,由于沥青质在岩石上的吸附和/或沉淀以及它们的重力分离,会发生油组分的重新分布。更致密的沥青质聚集体集中在油藏模型的底部。
