... to be smaller. The arch effect is caused by the following mechanism. When a portion of the bottom plate descends due to bending of the whole plate, a relative displacement occurs between the particles. A particle arch is formed in an oblique direction due to inter-particles friction. The force caused...

... annular clearance and high circulating friction. The annulus clearance of salt-paste layers in the Kuqa piedmont is only 17.5 mm, which is a typical borehole with small clearance and high circulating friction (0.08~0.15 g/cm3), leading to a high risk of cementing loss. High eccentricity of pipe string...
