1. The DACP used in drilling fluid is a cellulose derivative derived from heteroglycan, which is obtained by optimizing various natural plant gums and cellulose through processes such as alkylation. It possesses the physical and chemical properties of both heteroglycan and cellulose, making it an environmentally friendly additive for drilling fluids with multiple functions including filtration reduction, lubrication, inhibition, and rheological adjustment. Its linear macromolecules composed of cyclic polyhydroxy molecular structural units enable it to exhibit enhanced performance in terms of filtration reduction, inhibition, and lubrication when incorporated into water-based drilling fluids. The recommended dosage range for DACP is 3.0-5.0% (w/v), while at a dosage level of 10.0% (m/v) in water-based drilling fluids, it exhibits self-gel plugging effect.
