Details Description
• FC-632S has a high viscosity of low shear rate, which can effectively enhance the suspension stability of the cement slurry system, maintain the fluidity of the slurry, prevent sedimentation at the same time, and have good anti gas channeling performance.
• FC-632S has good versatility and can be used in a variety of cement slurry systems. It has good compatibility with other additives. Based on FC-631S, the product has improved its salt resistance and is more suitable for saline environment.
• FC-632S is suitable for wide temperature with high temperature resistance up to 230℃. After use, the fluidity of cement slurry system is good, stable with less free liquid and without retarding set and the early strength at low temperature develops quickly. FC-632S can be used alone. The effect is better when used together with FC-650S, which is suitable for fresh water/salt water slurry preparation.
High-temperature oil fields face a unique set of challenges when it comes to well cementing. One of these challenges is the issue of fluid loss, which can occur when the drilling mud filtrate invades the formation and causes a reduction in the fluid volume. To solve this problem, we have developed a specialized fluid loss reducer that is specifically designed for use in high-temperature oil fields. FC-632S is a kind of fluid loss additive control and it is suitable for Russian market.

Indeed, it is generally clearly acknowledged that a lack of fluid loss control may be responsible for primary cementing failures, due to excessive density increase or annulus bridging and that formation invasion by cement filtrate may be deleterious to the production.
