Description
SYJ_1 is one kind of high molecule weight polymer mixed
with some special materials. It can stick on the surface of cement
particles and modify the physical and chemical function of cement
particles. So it forms a net aggregate with the cement particles as its
knots. It narrows the micro porous and forms a compact filter cake, so
it can control the fluid loss effectively. The slurry which is applied
SWJ-1 has leak-protection and anti-migration functions. Mixed with
appropriate thickening-time adjustor, the slurry could meet the
operating standards.
SYJ_1 can be applied to any class of API oil_well cement.
It can be used by wet mixing and dry mixing. Mixed with extender
material, such as microsphere, bentonite, flyash, ilmenite, barite, it
could be mixed into different density. Both fresh water and seawater can
be used in the slurry. When it is used with seawater, we must increase
the quantity of the dispersant. It is suggested that SYJ-1 can be used
with retarder SYH-1, SYH-3etc.
