In this paper,the lithologic formation features of Weizhou XX oilfield in South China Sea is analyzed from the perspective of mechanics.Then,the appropriate analytic methods of hole stability for this oilfield is proposed.It also analyzes the relation among well deviation,drift azimuth and wellhole stability,concludes the regularities,and develops some favorable protective suggestions for wellhole stability in this oilfield.Reasonable design of directional wellhole track is one of effective measures to prevent wellhole instability in Weizhou XX oilfield of western South China Sea.
