Anti-temperature loss control agent for drilling fluids.CS-501A
Product Features and Applications
CS-501A is a high-temperature resistant deformable polymer lost circulation control agent. Under the pressure differential, the particles spread and deform on the wellbore wall, forming a low-permeability sealing film at the pore throat, preventing drilling fluid from permeating and effectively reducing drilling fluid lost circulation. It is suitable for various water-based drilling fluid systems and easy to use. The product is environmentally friendly and non-toxic.
Product Advantages
Temperature resistance up to 160℃;
Forms a low-permeability sealing film on the wellbore wall, effectively reducing drilling fluid lost circulation;
Low viscosity effect, minimal impact on drilling fluid rheology;
Environmentally friendly and non-toxic.
Performance
Recommended dosage
Recommended dosage is 1-3% and can be adjusted according to construction requirements and downhole conditions.
