The well HA10-1X is located in Northern of Tarim Basin, which some downhole problems are encountered before the first and second stage cementing, such as low formation pressure, lost circulation and long cementing segment, so in this well, the dual thickening time and density cement slurry system and heavy drilling fluid replacement technology are used to reduce operation pressure. In the first stage cementing, the 1.45 g/cm3 and 1.88 g/cm3 cementing slurry is applied in 3,800 m-6,758 m, in the second stage, the 1.45 g/cm3 cementing slurry is used in 0-3,001.64 m. The result of CBL shows that the cementing job quality is qualified, and the cementing quality is improved by this cementing technology.
