D2569 is a specially treated starch compound that has been chemically modified tohave better temperature resistance, salt resistance, calcium resistance and other properties. In drilling fluids, it can effectively control fluid loss, reduce drilling fluid damage to the formation, and improve the stability and recycling rate of drilling fluids. It can also be used with acid-soluble bridging agents in saturated brine to prepare clay-free acid-soluble completion fluids. In addition, D2569 also has good environmental performance and will not cause pollution to the environment.
