Detailed
Description
SWJ_6 is one kind of high molecule weight polymer mixed with some assistant materials. In cement slurry ,it can be adsorbed onto the partical surface effectively, change physical chemistry performance. forming a cross_linked net among polymer molecules. Then it can form a compact film when the certain pressure differential occurred between the slurry and the formation. The slurry applied SWJ_6 has leak_protected and anti_migration functions. Mixed with proper thickening_time adjustor, the slurry could meet the operating standards.
SWJ_6can be applied to API oil_well cement. It can only be used by dry mixing peocess. Mixed with microsphere, bentonite, flyash, ilmenite, barite, it could be mixed into different density. Both fresh water and seawater can be used in the slurry.
