大量自生高岭石发育所需的开放-半开放流体体系同时也有利于油气富集。

This paper presents the authigenic CO2 flooding mechanism and selects the authigenie CO2 flooding system based on taking reaction speed and economic factors into account. Evaluation is conducted on the effect of the selected CO2 system on expansion viscosity reduction in crude oil. The flooding mechanism and effect of the system is studied by using microscopic models and physical models.
