Cement sheath integrity of shale gas wells: A case study from the Sichuan Basin
Sustained annulus pressure and casing deformation of gas wells are common in several shale gas demonstration areas in the Sichuan Basin. In view of this, the conditions for pressure change inside the wellbore in the process of drilling were analyzed, and then an elastic–plastic mechanical model of c...
