Shan Xi Wei Dayton Cement Group Co., Ltd. Share: oil well cement into ABC three C-class C-class oil well cement cement suitable depth to 1830m depth range of ground, divided into common type, anti-sulfate type and high resistance to sulphate three types, C grade cement C3A content and specific surface area are high, so it has early strength characteristics. Class C cement is roughly equivalent to ASTM standards Ⅲ cement. To meet the early strength and resistance to sulphate requirements generally used high-fine grinding clinker and fired to produce a specific composition C-class oil well cement. The main factors affecting the C-class performance include oil well cement clinker, gypsum and cement fineness content and so on. Witton Cement Group Co., Ltd. Share: low oil well cement early strength agent Research and Evaluation Summary: low early strength cement slurry is designed to meet the low temperature conditions to produce a kind of cementing grout, aiming at Daqing oilfield drilling during winter When surface casing cementing formation temperature is low, slow cement strength development, WOC long time and so developed a new type of low-temperature coagulant early strength agent QZ-1, the early strength agent is active silica fume, Solid alcohol amine and an anionic polymer compound obtained by a certain percentage, and can greatly accelerate the rate of hydration of cement cement plant in Shanxi well, promoting the formation of the early strength cement; the early strength agent does not contain chlorine ions, can overcome the traditional containing oil well cement casing corrosion problems caused by chlorine early strength agent, oil well cement plant at the same time, the early strength agent active silica fume contained, can react with the cement, so that a slight expansion of the volume of cement; solid alcohols and amines can cement particles and water molecules of hydrogen bonds and van der gravitational binding cement particles are adsorbed Shanxi oil well cement and deepen the depth of cement hydration reaction; there are a large number of adsorption groups (hydroxyl, amide) and hydrated anionic groups on the polymer chain ( carboxyl), can be adsorbed on cement particles, increasing the viscosity of the cement slurry. QZ-1 early strength cement slurry affect performance, including compressive strength of the experimental study analysis.
