摘要: Abstract Based on influence of porous flow weak plane model, the authors established a mechanical model borehole stability for formation under and analyzed effect flow. The results indicated that decreased strength plane, enlarged affecting domains rock mass strength, worsened instability in formations. With increasing, water content increases. For with DIP 30°, it is opposite to situation 10° < 30°. While next be saturated, minimum drilling fluid density does not change azimuth worst. ...
