Modified sulfonated tannin viscosity reducer is an oil drilling fluid additives, which can effectively eliminate the
formation of drilling fluids due to soluble salts and thickening caused by high temperature in order to ensure
good drilling fluid rheology. It is the use of gallnut in the reactable substances in the presence of
formaldehyde, sulfite sulfonated by condensation, and then by complexation of heavy metal salts derived. Due
to gallnut tannin as raw material, reducing production costs, combined with the synergistic effect of various
components of gallnut tannin, improve the product's salt resistance and temperature resistance.
Physical and chemical standards
Drilling fluid properties
As the product can well maintain the drilling fluid performance, less dosage, long processing cycle, not only reduce the labor intensity
of workers and improve the drilling speed, and the high success rate of electrical measurement, cementing quality and reduce the total
cost of drilling At the same time, industrial production has no waste, basically no pollution to the environment, the product does not
contain harmful metals, reducing the pollution of formation water.
