The response of electromagnetic wave logging while drilling is influenced greatly by borehole and drilling fluid resistivity when the size of borehole is relatively large and drilling fluid resistivity is low. Borehole radius and drilling fluid resis

Annular drilling fluid between the drillstring and borehole wall has a great influence on lateral vibration of drillstring and the influence involves the added mass. Assuming the drilling fluid is incompressible, we derive the added mass coefficient

Abstract During drilling operation in carboniferous system of Dzungaria basin, igneous rock was met, which leads to a low penetration rate and long drilling cycle, because of large thickness, high hardness and poor drillability of the igneous rock. Q
