CEMENT SLURRY SYSTEM, PREPARATION METHOD THEREFOR AND USE THEREOF
The present disclosure relates to the technical field of oil and gas field exploitation, in particular to an early strength material suitable for a cement slurry system, a cement slurry composition, a cement slurry system, a preparation method therefor and the use thereof. The early strength material contains an aluminum salt, a sodium salt, crystal whiskers, an inorganic mineral and dispersing agent I, wherein the weight ratio of the aluminum salt, the sodium salt, the crystal whiskers, the inorganic mineral and dispersing agent I is (1-3):(1-3):(1-4):(1-8):1. The early strength material provided by the present invention has both high-temperature retarding performance and low-temperature early strength performance; meanwhile, while satisfying well cementing, the cement slurry system prepared from the cement slurry composition containing the early strength material can prolong thickening time of cement slurry under a high-temperature condition, can prevent ultra-retarding of top cement slurry under a low-temperature condition and has increased early strength.
