Selection of the drilling fluid density as specified with the expected deformation of the cross-section of the well

Abstract During inclined and horizontal drilling, the cross-section of the well is deformed in the form of uneven displacement of its walls, which is one of the reasons for tightening and tool sticking. To limit the displacement of the walls, it is proposed to adjust the density of the drilling fluid taking into account the elastic properties of the rock and the angle of curvature of the well.
