In oil drilling projects, a seemingly ordinary white or light yellow powder - HEC (hydroxyethyl cellulose) series is reconstructing work efficiency and safety. The HEC series is synthesized by precise etherification reaction of alkalized cellulose and ethylene oxide. With its unique molecular structure, EASONZELL™ HEC series has become an important component of the drilling fluid system.
- Product essence: balance between safety and performance
Physical form: white or light yellow powder/fibrous solid, high fluidity, easy to accurately feed.
Safety performance: HEC (hydroxyethyl cellulose) series is odorless and non-toxic, meeting the standards of green environmental protection and occupational health.
Product function: During use, it can quickly increase the viscosity of drilling fluid and optimize the cleaning efficiency of the wellbore; stably carry drill cuttings, prevent sand from settling at the bottom of the well, maintain the stability of solid and liquid materials, reduce the risk of stratification, and the product can also lock free water and reduce filtration and permeability.
- Full cycle application: throughout the core process of drilling
