Product Description

Drilling Fluid Encapsulating Agent PAC-141

PAC-141 is a water-soluble polymer synthesized by copolymerizing various 
anionic, nonionic, and organic cationic monomers. It dissolves easily in water and serves to inhibit shale cuttings dispersion and increase drilling fluid viscosity. It has strong encapsulation and inhibition properties, high tolerance to shale cuttings contamination, and is easy to purify after contamination. It also reduces submicron particle content in the system, helping to enhance drilling speed and protect the formation.

Performance Characteristics

1. Strong inhibition and coating effects;

2. Unique "anti-polyelectrolyte" solution behavior;

3. Good compatibility.

Product application:Oil and gas drilling fluids
