Abstract：Geological storage of carbon dioxide is one of the effective techniques to reduce CO 2 emissions.E-valuation of capacity and suitability of such storage can provide a scientific foundation for policies of reducing greenhouse gas emissions.This work collects and analyzes the relevant data from the studies of petroleum geologyand engineering and hydrogeology.The porosity and thickness of carbonate formations in the basins of China mainland are investigated.A series of important geological maps related to CO 2 storage in carbonate formations in these basins are prepared,including the “Classification map of areas of carbonate formations in the basins of China”,“Classification map of thicknesses of carbonate formations in the basins of China”,“Classification map of porosities of carbonate formations in the basins of China”,“Classification map of CO 2 storage capacity of carbonate formations in the basins of China”,“Classification map of suitability of CO 2 storage in carbonate formations in the basins of China”.After suitability evaluation and removal of those ba-sins not suitable for CO 2 storage,the basins with high suitability for CO 2 storage are chosen for further in-vestigation.
