Performance Evaluation of and Research on Anti-Gas Channeling Cement Slugs

  • Published:
Chemistry and Technology of Fuels and Oils Aims and scope

Slug anti-gas channeling technology was studied in laboratory experiments to optimize the micro-expansion behavior of its material. The technology included sealing of an outer pipe, injection of cement slurry into the casing annulus, and activation and solidification of the cement slurry as a function of temperature and other external conditions. The technology could effectively seal an oil or gas well and solve the problem of wellhead pressure.
