HPS is a non-ionic high molecule material. It is no sensitive to any heavy metal ions, and has a excellent contamination-resistant to salt and calcium in drilling fluids .Specially , it has a better function than CMC in muds withCa2+contamination. HPS has a excellent solubility in acid and can be used to prepare the saturated salt water , no clay phase , acid soluble oil well completion fluid together with the acid-soluble bridging agent (QS). HPS can effectively reduce the water filtration of the cationic or amphiprotic complex ionic polymer drilling fluids. Otherwise , HPS is also used to prepare the preflush & spacer and the workover fluid in the oil well cementing and workover operation . |
