Due to the advantages of low Young modulus, high Poisson ratio, strong impact resistance and the like, the elastic and tough cement is widely applied to high-temperature and high-pressure ultra-deep gas wells in Xinjiang area, shale gas wells in southwest area and special working condition wells (such as gas storage circulating injection and production and the like).
At present, many researches on elastic and tough cement paste systems are carried out at home and abroad, the mechanical property of the set cement is mainly improved by two modes of 'endogenous type' and 'exogenous type', the exogenous type mainly improves the mechanical property of the set cement by adding an elastic and tough material into cement ash (for example: Dingshiwei. a low-temperature high-toughness cement paste and a preparation method and application thereof: CN 106986584A, Jianzhou. an expansion toughness well cementation cement paste and a preparation method thereof: CN 104371678A, Shizhongnan. air reservoir well toughness cement paste: CN 107699216A and the like), and the elastic and tough materials mainly comprise four types, namely: the material is characterized by comprising four materials, namely fiber, rubber particles, latex and resin, wherein each material has respective performance advantages, but the material cost is generally high, the temperature resistance is difficult to guarantee, the construction and debugging are complex, and the like, so that the material is not beneficial to field application.
Therefore, research on the elastic and flexible cement slurry system tends to improve the toughness and mechanical deformation capability of the set cement in an endogenous mode so as to reduce cost and improve efficiency, the endogenous mode is mainly started from the cement production link, the content of mineral components in the cement is changed, the particle tight packing principle is utilized, the purpose of reinforcing and toughening the set cement is achieved, and the commercial development value of the endogenous high-strength toughened well cementation cementing material is highlighted.
