Oil-drilling Grade

HEC is mainly used as a thickening stabilizer in the oilfield treatment process, which has the characteristics of good thickening effect, strong and stable sand suspension ability, heat resistance, high salt holding capacity, small pipeline resistance, fast rubber breakage, and low residue, and is a better oilfield chemical.

HEC is mainly used as viscosifier and fluid loss agent in oil drilling industry. High-viscosity. HEC with high-viscosity is mainly used as viscosifier in well-completing or finishing fluid; and HEC with low-viscosity is mainly used as fluid loss agent.
