Technological challenges for CO2 EOR in China
Journal Title: Science Paper Online - Year 2007, Vol 2, Issue 7
Abstract
It is well known that, in China, the physical property of reservoir is poor and crude oil has characteristic such as high viscosity, high wax & resin content, high freezing point, etc. So, the CO2 EOR will face problems like high miscibility pressure, severe gas channeling, organic solid deposition and application of the technology in complicated reservoir. Some new research progress about the change of physical property of reservoir, apparent permeability of CO2 in reservoir and sweep efficiency enlargement in the CO2 injection process are summarized. Beside that, new idea for the implementation of CO2 EOR and emphases in the research of that technology are also presented.
