| Abstract: | In order to solve the problem of core drilling in super thick unconsolidated stratum, a new technology of using a double-layer casing to insulate the super thick unconsolidated stratum and the casing insulating liquid developed by the authors to protect the sleeve and keep the weak stratum stable was put forward on the basis of systematically analyzing all the factors which may affeet the hole safety during drilling engineering and construction of super thick unconsolidated stratum. Practices have proved the feasibility of the new technology. |
