Description
ScCO2 was used as the solvent and intercalator when micro crystalized Ca-montmorillonite(MC Ca-MMT) was modified from Ca-MMT powder. With micro crystallization, carbonates crystallite was produced between Ca-MMT layers and provided active sites for the further reaction when mixed with oilwell cement. Enhanced oilwell cement by MC Ca-MMT was investigated based on the mechanical property and microstructure variations after curing in accelerated carbonation conditions. The microstructure of carbonation layers in enhanced oil well cement was observed and calculated according to the CT scanning results.
