Discussion on Drilling in Complex Strata with Managed Pressure Drilling
Abstract:Water-gushing in sandstone and sand-shale collapsing were effectively solved by managed pressure drilling technology in Yaozhuang coalfield, which played important role in improving drilling efficiency and reducing construction risk. The practice provided the construction experience for drilling in this area.
