  • Cement slurry treated with latex nano liquid silica anti-gas-migration agent has been studied for the possibility of using it in Shunnan area, where ultra-deep wells have penetrated high temperature high pressure formations. The nano liquid silica anti-gasmigration agent and latex anti-gas-migration agent are both used to synergistically enhance the anti-gas-migration performance of the cement slurry. By optimizing the particle sizes and concentrations of the silica powder, the high temperature stability of the set cement can be improved. Inorganic fibers are added into the cement slurry to stop the development of fractures, thus controlling the losses of cement slurry and improving the shock resistance of the set cement. This cement slurry has good mobility, API filter loss less than 50 mL, right-angle thickening curve, and SPN less than 1. The set cement has good high temperature stability, high bond strength, and high shock resistance. Cement slurry with density of 1.92 g/cm3, after aging at 190℃ and 21 MPa for 30 h, has strength (measured with ultrasonic wave method) gradually stabilized, and interface (between casing string and cement sheath) bond strength of 12.6 MPa. Compared with conventional cement slurry, the elastic modulus of the set cement has been reduced by 52%, and the shock resistance increased by 188%. Striking the set cement with Hopkinson bar has only left several pieces of fractures that do not penetrate the set cement. This cement slurry has been successfully used in the cementing of the well Shunnan5-2 and well Shunnan6, overcoming the difficulties encountered in ultra-deep gas well cementing.
