Research on vertical structure stability before cementing ultra-deep wellbore by drilling method

To address the problem of vertical stability of ultra-deep wellbore by drilling method, firstly, the results of the equation of critical height of equal section for non-full counterweighted water drilled wellbore are compared with the results of the equation of critical height of the wall of a varia...
