The required physical properties of the cement are essential before commencing cementing operations. The proper set cement is also determined, including the density and viscosity of the material, before actually pumping the cement into the hole.
Special mixers, including hydraulic jet mixers, re-circulating mixers or batch mixers, are used to combine dry cement with water to create the wet cement, also known as slurry. The cement used in the well cementing process is Portland cement, and it is calibrated with additives to form one of eight different API classes of cement. Each is employed for various situations.
Additives can include accelerators, which shorten the setting time required for the cement, as well as retarders, which do the opposite and make the cement setting time longer. In order to decrease or increase the density of the cement, lightweight and heavyweight additives are added. Additives can be added to transform the compressive strength of the cement, as well as flow properties and dehydration rates. Extenders can be used to expand the cement in an effort to reduce the cost of cementing, and antifoam additives can be added to prevent foaming within the well. In order to plug lost circulation zones, bridging materials are added, as well.
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.
