Oil well cement flexibilizer
The invention discloses an oil well cement flexibilizer. The oil well cement flexibilizer can be used as an admixture for oil well cement of oil-gas well cementing, and is prepared from the following components in parts by mass: 15-50 parts of a temperature-resistance rubber material, 0-20 parts of surface modified fibers, 10-20 parts of a stabilizer and 10-50 parts of a rheolobic modifier. The flexibilizer can be used for reducing the elasticity modulus of annulus set cement and improving the impact resistance of set cement, and is well compatible with other cement admixtures. The flexibilizer has stable normal-temperature and high-temperature performances, and can be used for improving the rheological property of cement paste, solving the problem that the annulus set cement in an oil-gas well has poor stress resistance and cannot adapt to big-frac treatment in the oil and gas exploitation process, and prolonging the service life of the oil-gas well.
