Abstract The Langgu sag, one of the three sags rich in oil in the Jizhong Depression, north China, is the main oil producing area of Huabei Oilfield. The reservoirs are deeply buried and the formation temperatures are high. The well Antan-1x is an exploratory well drilled in this area. This well had complex well profile, and the 127 mm liner (in 4th interval) was run to 5,494 m, at which the formation temperature is 177 °C. Gas zones at the completion depth are very active and are difficult to control with high density drilling fluids. Narrow annular spaces and hence thin cement sheaths impose challenges to the high temperature stability and anti-channeling ability of cement slurry, and the compressive strength of set cement. A high temperature anti-channeling cement slurry was formulated for use in the well Antan-1x. This cement slurry has good anti-settling performance and ability in minimizing the amount of free water.

and the settling rate of the spacer under 180 °C was less than 0.03 g/cm°. In
cementing the p 127 mm liner string of the well Antan-1x, high quality cementing job was done with the high temperature cement slurry and the spacer, laying a good foundation for the later exploration and development of the Jizhong depression in north China Key words Deep well; High temperature; Cement well with narrow annular space; Anti-channeling; High temperature anti-channeling cement slury; Pollution-resistant flushing spacer, Langgu sag
