    Abstract
  • The cold sea area in polar region of the earth possess huge reserves of oil and gas, cementing of the wells developing these oil and gas is not able to be completed using conventional cement slurries because the water in the cement slurry gets frozen in cold temperatures in polar region, and the hydration of cement is unable to proceed. A cement slurry has recently been developed for use in this cold area, and the products of hydration at -18 ℃ and at room temperature were compared microscopically. Laboratory experimental results showed that the cement slurry developed has excellent setting performance at cold temperatures; at -18 ℃, the cement slurry sets in 0.5-3 h, and the 24 h compressive strength falls between 3.5 and 9 MPa, indicating that the cement slurry can be used to resolve the problems conventional cement slurries have to face with: being unable to set and having no strength at cold temperatures. Microscopic test of the cement slurry shoed that the hydration degree of the cement slurry at -18 ℃ is lower than that of the cement slurry at room temperature, while the Aft content of the cement slurry at -18 ℃ is higher than that of the cement slurry at room temperature, a phenomenon that is positive to the mechanical properties of the set cement.
