Description
SYJ_4 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 SYJ_4 has leak-protected and anti-migration functions. Mixed with proper thickening-time adjustor, the slurry could meet the operating standards.
SYJ_4 can 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. It is suggested that SWJ_4 can be used with retarder SYH-1, SYH-3etc.
