Molecular Modeling of Phase Behavior and Flow in Shale Porous Media

过去几年页岩气和致密油行业的蓬勃发展激发了人们对勘探和生产活动的浓厚兴趣。加拿大的页岩气可采储量估计为573万亿立方英尺，可以提供100年的天然气供应。针对可靠的碳氢化合物相态和流动模型的研究是预测页岩地层天然气和致密油产量的关键。然而，页岩非常规油藏与常规油藏有很大的不同，常规油藏中的烃类存储在裂缝和大孔隙中，这些裂缝和大孔隙一般大于100 nm。

Booming in the shale gas and tight oil industry in the past few years has stimulated profound interest in exploration and production activities. The recoverable shale gas in Canada is estimated to be 573 trillion cubic feet, which can provide 100 years of natural gas supply. Studies directed towards the development of reliable phase behavior and flow modeling of hydrocarbons is key to predict the gas and tight oil production from shale formations. However, shale unconventional reservoirs are very different from the conventional reservoirs where hydrocarbons are stored in fractures and big pores which are generally larger than 100 nm.
