Description ST-JSCL141 is a kind of organic acid. Under 100°C, it can linearly prolong the thickening time effectively by adding SWH-1in slurry. ST-JSCL141 has good compatibility with other additives. ST-JSCL141 can be applied to API oil-well cement. Mixed with density adjustor, such as microsphere, bentonite, flyash, ilmenite, barite, it could be mixed into different density. It is suggested to be used together with SWJZ series dispersant 。So as to get slurry with excellent comprehensive property.
