Abstract
Xinjiang is the major energy production area, and one of the regions with the most serious water resources scarcity issues in China. In particular, the coal-fired power and coal chemical industry base in East Junggar Basin has faced severe carbon emissions and water shortages. Based on the 3D heterogeneous geologic model of the East Junggar Basin, the research of field-scale CO2 enhanced water recovery (CO2-EWR) was carried out to provide technical reference for the future field-scale CO2-EWR engineering practice in Xinjiang to solve the carbon emission and water shortage issues. The CO2-EWR technology can greatly relieve the reservoir pressure buildup, with a maximum cumulative CO2 injection and storage of 100 Mt (3 times more than CO2 Geological Storage only) and a maximum saline water production of 129.4 Mt (100 times more than saline water production only).
