Detailed
Description
SYJ_2 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 certain pressure differential occurred between the slurry and the formation. The slurry applied SWJ-2 has leak-protected and anti-migration functions. Mixed with proper thickening-time adjustor, the slurry could meet the operating standards.
SYJ_2 can be applied to API oil_well cement. It can only be used by dry mixing process. Mixed with microsphere, bentonite, flyash, ilmenite, barite, it could be mixed into different density. Only fresh water can be used in the slurry. It is suggested that SWJ-2 can be used with retarder SYH-1, SYH-3etc.
