Process for improving the physicochemical properties of polymer solutions employed in oil services |
摘要 |
The removal (for example by ultracentrifuging) of the microgels and debris present in the polymer solution, especially of polysaccharide. Essential properties, such as the conveying of the supporting agents, are thus improved and the residues are decreased after the gel is broken. Applications in well fracturing and cementing. <IMAGE>
