PRODUCT DESCRIPTION
The Sulphonate copolymer STP additive for drilling fluids is synthesized from acrylamide (AM), acrylic acid(AA), sulfonic acid (AOBS), epichlorohydrin, and a new ring structure of cationic monomer under the effect of the initiator through many multi-step polymerizations. STP can improve the viscosity of the mud effectively, reduce the amount of filtration, and improve the quality of mud pie, inhibit clay dispersion, flocculate cuttings, and control solid content as well as the formation mud-making. It is helpful to protect the reservoir, especially suitable for sea water to drill deep and ultra-deep wells. The typical concentration is between1%-1.5%.

TECHNICAL SPECIFICATION

FEATURES
1. It can reduce filtration loss.
2. It can improve mud cake and inhibit viscose soil being dispersed.
3. It has a good stability and stands 200℃.
4. It has a strong capability of resisting salt, calcium and magnesium. And it can be applied in fresh water, seawater, and saturated salt water and Brine for completion drilling fluids.
5. It helps to stabilize the borehole and reduces the expansion of borehole.
6. It can limit the solid and protect the oil region with gas.
7. It can match with other agents well.
