Summary
ZOD-FLOTROL is a kind of crosslinking starch. Crosslinking starch reduced its light transmittance, enhanced acid alkali-resistance, resistant to mechanical processing, the shear resistance and performance of gel. The main function of this product in the drilling fluid is to adjust the rheological properties of drilling fluid system, improve ratio of dynamic shear force in drilling fluid system, can keep high viscosity when bit is in a relatively static to prevent the wall collapsed. It can improve the carrying capacity of drilling fluids, maintain the cleanness of borehole in the rapid drilling phase. It has good filtration performance and good resistance of calcium and salt. Its performance is superior when working in the sea and salt bed. ZOD-FLO TROL is applicable in freshwater drilling liquid, saltwater drilling liquid and seawater drilling liquid. It has good compatibility with other additives.
Usage range
