Abstract In cementing the p 177.8 mm liner string in high pressure gas wells in the Block Gaoshiti-Moxi of southwest oilfield, problems such as active gas zones, narrow drilling windows, poor compatibility of fluids and large temperature difference at high aeea sa ea eda a seaeaae high density cement slurry was developed for cementing wells with large temperature difference at high temperatures. Laboratory study of the cement slurry showed that the cement slurry had density between 2.0 g/cm’ and 2.8 g/cm', and in field application, the cement
slurry can be prepared to have a density of 2.6 g/cm’ in room temperature and 180 °C. Differences between the

The thickening time had good linear relationship with
the concentration of retarders, and the transit time for the thickening of the cement slurry was not longer than 10 min. The maximum transit time of the gel strengths of the cement slurry was 20 min. The 24-hour compressive strength of the set cement was greater than 10 MPa, and the 48-hour compressive strength of the cement top was greater than 3.5 MPa. The strength of the cement slurry developed fast at low temperatures. The set cement formed had stable non-shrinking volume, possessing a mechanical performance that is similar aaaoe o aennaeeoaeoa aaedansaaeaaaeoroeo
