Description

SYJ_3 is an update soluble polymer which is synthesized and designed to control slurry fluid loss. Through the double role of absorbing and accumulating, SYJ_3 forms a kind of weak_cross_linked colloid in the slurry. So it can inlay the mud_cake steadily, and stick on the surface of cement particles to minimize its micro porous. Thus it effectively controls the fluid_loss of slurry through tincreasing the slurry viscosity and decreasing permeability of mud_cake. This update fluid loss controller can be applied in wide working temperature range and salt_resistant. Mixed with compatible dispersant, retarder, etc. it could protect the oil and gas zone and leading successful cementing operation.

SYJ_3 can be applied to API oil_well cement. And it can only be used by wet mixing process. Mixed with density adjustor, such as microsphere, bentonite, flyash, ilmenite, barite, it could mixed into slurry with different density. It is suggested that SYJ_3 can be used with retarder SYH_1, SYH_5, etc
