Open publisher page 0 citations

Abstract

The development of directional well in Changqing gas field has increased because of the necessity of the wide exploration.It were analyzed that how to optimize the well diagram design,to select a PDC bit and drill string structure and drilling fluids so as to speed the drilling velocity and shorten the drilling period,and the technical characteristics and experience of drilling directional wells were summed up to give references for developing the gas field widely.
