Products for ultra-high temperature cement slurry systems
The cement slurry system with fluid loss additive CG811S and retarder CH710L as the main agents is suitable for ultra-high temperature wells, with a temperature resistance of up to 210°C, normal slurry fluidity, adjustable thickening time, and a "right angle" thickening curve.
-
Anti-supersaturated salt water products
Salt-resistant and accelerating type fluid loss additive CG610L can control water loss in supersaturated salt water cement slurry system, shorten thickening time, and develop cement strength quickly, thus meeting the safety requirements of on-site construction.
-
Products to solve cement slurry thickening time and strength reversal
The CG613S fluid loss additive ensures normal water loss performance while preventing reversal of thickening time and strength. It is compatible with various oil well cements and is widely used in domestic oilfields like Liaohe, Jidong, Dagang, and Jianghan.
-
Low temperature accelerating type fluid loss additive
The CG9 series fluid loss additives (CG910S, CG911S, CG912S) reduce fluid loss and accelerate setting at low temperatures. They ensure short thickening times, quick early strength development, and high strength values.
-
Solutions for the poor dispersion of high-density cement slurry
The CG116S fluid loss additive, for high-density cement slurries, offers strong dispersibility for low-resistance pumping. It features a short thickening time, rapid early strength development, a brief setting transition, and good anti-gas channeling properties.
-
Products improving the fluidity of seawater cement slurry
The fluid loss additive CG117S, which is suitable for seawater cement slurry system, has a polydisperse star-shaped structure and can effectively overcome the gelation and thixotropy problems caused by seawater slurry preparation, ensuring that the slurry has good fluidity.
-
Products that are simultaneously resistant to multiple salts
CG714S is designed for low-density cement slurries, compatible with various inorganic salts (CaCl2, Na2SiO3, NaAlO2). It maintains normal fluidity, sedimentation stability, thickening performance, and water loss, meeting on-site construction needs effectively.
-
Solutions for the poor sedimentation stability of low-density cement slurry
CG212S fluid loss additive is tailored for low-density cement slurries, enhancing thickening and suspension effects. It improves stability and ensures strong cement stone development, optimizing thickening performance.
