The product is a kind of polyacrylamide copolymer, which can effectively prevent drilling fluid and filtrate from invading the formation, thus causing shale expansion and collapse and causing borehole wall instability. This series of polymers is resistant to different formation temperatures and high salts, and exhibits excellent filtration loss performance in the range of 100-250℃ in both clear water and salt water.

This product is a kind of polyacrylamide copolymer, which can maintain the stable drilling fluid performance, inhibit the shale hydration expansion and keep the drilling cuttings from dispersive, easy to remove. This series of polymers has a molecular weight of 2-8 million, and has a good coating effect on cuttings in fresh water and salt water as well as saturated salt water, with a temperature tolerance of more than 130℃.

This product is a solid powder or emulsion of a polyacrylamide copolymer used in water-based fracturing fluids to reduce the friction coefficient when fracturing fluids flow, thus reducing pressure loss. The powder or emulsion resistance-reducing agent can disperse and dissolve in water quickly, with quick effect, and can be applied to on-site mixing equipment. In addition, this series of products also has good salt resistance performance, can be suitable for the backflow of fracturing fluid reformulation and reinjection.

This product is a class of cationic or amphoteric ionic copolymer solid powder, which is used in acidizing or acidizing fracturing technology, used for acid pressure (chemical) transformation of carbonate reservoir, to delay the reaction rate and filtration rate between acid and reservoir rock. The product can dissolve and viscosify rapidly in acid solution, and has the characteristics of high temperature resistance (120-180℃) and salt resistance, good compatibility, outstanding friction reduction performance, can effectively reduce the acid/rock reaction rate and acid filtration rate, and expand the radius of acid treatment.

This product is a series of cationic oligomers or condensates or copolymers, which can effectively avoid formation damage caused by clay swelling and migration, thus increasing oil and gas production. The series is environmentally friendly and can be used in drilling and fracturing processes to provide continuous protection to the formation, and can be used with a wide range of additives for fracturing/drilling fluid products. This series of products are characterized by high temperature resistance and shear resistance.
