Working mechanism of nano-SiO2 sol to alleviate the strength decline of oil well cement under high temperature

Strength retrogression of cement stone is one of the major challenges in oil well cementing under high temperatures. Nano-SiO2 exhibits the potential to mitigate this problem, but there is lack of reports about the role of nano-SiO2 playing within cement stone under high temperatures. Therefore, in...
