文摘

Dynamic model of a horizontal oilwell drillstring, capturing longitudinal and torsional motions, has been presented. The torque and drag obtained from the proposed model are in qualitative agreement with field data. High amplitude and low frequency axial excitation force in the horizontal portion of the drillstring provides better weight transfer to bit.
