Abstract
In view of the“three low”characteristics(i.e.,low resistivity,low oil saturation and low permeability)of Oilfield in western South China Sea,water injection and energy supplement difficulties exist in the development process due to high irreducible water saturation and high shale content and strong water sensitivity. Based on laboratory researches and adaptability evaluations of gas injection of CO2 at home and abroad,and by taking reservoir as an example,laboratory experiment of CO2 gas injection and reservoir numerical simulation are finished,and theCO2 gas injection development adaptability evaluation is done on this foundation. A comparison among the depletion type development,continuous gas injection and WAG displacement through numerical simulation,the result shows CO2 gas injection development has good adaptability,and WAG can further improve the oil recovery of oilfield development.关键词
