摘要：

Based on the plane of weakness theory,a model for predicting borehole stability in fractured reservoirs under different stress states was estiblisted and the equations for solving borehole stability were developed.The minimum downhole pressures required to maintain borehole stability under different natural fracture occurrences were calculated by using the data from a well in the Tazhong (central Tarim) area,Tarim Basin,west China.Several conclusions were drawn for naturally fractured reservoirs with a dip angle from less than 10°to greater than 30°.Application in three wells in the Tazhong area indicates that this model is practically useful.
