Mathematical Model and Experimental Investigation of Bit-Bounce in Horizontal Oil Well Drillstring

The bit-bounce is detrimental to the service life of drillstring and bit. This study highlights the influence of axial excitation and torsional excitation on the bit-bounce in horizontal well. Because of the complicated surroundings of downhole, Hamilton principle, a kind of energy method, is employ...
