Well cementing binder

Viscosity is important when considering displacement mechanics. A low viscosity cement will have better displacement properties at higher flow rates, while a high viscosity cement may have better displacement properties at lower flow rates. In directional wells, solids separation is a concern. After the cement is placed and before it takes it initial set, the solids in the cement can settle toward the low side of the hole.

Settling will leave a lower density cement on the high side of the hole which is not desirable.

The viscosity and gel strengths of the cement will determine the likelihood of solids settling, and the degree to which it occurs.

Viscosity is controlled by the amount of water added to the cement. Only 25% water by weight of cement is required for hydration, but more water is added to provide for pumpability. Dispersants lower the yield point of cement slurries reducing friction and allowing turbulence to occur at lower pump rates. Using dispersants allows the cement to be mixed with less water yielding higher densities.

RF-9606 is polymer water dispersion made from butadiene, styrene and unsaturated carboxylic acid by emulsion polymerization. High chemical stability, good compatibility with cement paste, good adhesion between oil and water runny interface. After hydration, latex cement slurry can form a dense and impermeable system to effectively control water loss. It can improve the elasticity and compression strength of cement and effectively reduce the rupture degree of cement surface during perforation. It can improve the resistance of cement to fluid corrosion and improve the durability of cement.
