SMP is made under the high temperature by polymerizing phenol, formaldehyde and sulphonate.
This product is a good high-temperature resistant fluid loss additive, it can resist the high temperature that above 180?.
Divide into two types according to the salt resistance:SMP-ⅠSMP-Ⅱ
SMP-Ⅰ& SMP-Ⅱ.
SMP-Ⅰ can be used in the well drilling liquid that the degree of mineralization is below 100,000mg/L;
SMP-Ⅱcan resist the salt to saturation, the calcium resistance can reach 2,000mg/L, mainly used in saturated salt-water drilling fluid?
SMP carries out the standard of SY/T5094-1995.
