| Abstract: | Foam cement slurry is made from the mechanism of chemistry interaction between air-entraining agent and foaming agent. Nitrogen is produced in this process, and microballoon is used in the base slurry to further reduce the density. The cementing technology on field is described in detail, which includes density design, cement dosage calculation, additives mixing and field operation practice. It is successfully used in Changqing Oilfield, where the formation fracturing pressure is low and lost circulation is highly potential, thus cementing of large section of interval as long as 1500m or longer is required. This technology can also be used in cementing the well that requires heated recovery. |
