  • Wells in northwest Sichuan are being drilled deeper and deeper. In west Sichuan, exploration activity has extended to the depths of the lower Permian Series and the Cambrian System. In the west of Sichuan cementing of complex ultra-deep wells has to be faced with multi pressure systems along the wellbore, and narrow drilling windows. Using conventional liner cementing techniques, the ultra-deep wells are unable to be cemented effectively. To address the problems in liner cementing, i.e., the coexistence of blowout and lost circulation in ultra-deep wells, well cementing under dynamically balanced pressure was practiced in wells penetrating pressure sensitive formations, and a set of techniques, including annular pressure control when cementing a well with narrow safe drilling windows and anti-channeling cement slurries. The techniques have first been successfully applied in cementing the φ114.3 mm liner in the well LG70 under managed pressure, ensuring the job quality of cementing a well with small annular clearance, high temperature and coexistence of blowout and lost circulation. These techniques have also been successfully used on many other wells, providing a whole new technology for the prevention of channeling and lost circulation in cementing wells with narrow safe drilling windows.
