| 摘 要： | 应用多孔弹性理论，导出了斜井井壁周围的应力表达式，并提出了新的斜井水力压裂裂缝起裂判据，它不但考虑了垂井裂缝产生的机理，而且还考虑了水平缝产生的机理，新的斜井水力压裂起裂判据比以往的斜井水力压裂裂缝起裂判据更具合理性．

| Abstract: | The fracturing of highly diviated well was analyzed with three dimensional poroelasticity,Some formulas for determining the stress components around the borehole were derived.A new hydraulic fracturing criterion for highly deviated wells was developed,with consideration of the mechanisms of horizontal fracturing and vertical fracturing. |

| Keywords: | Hydraulic fracture Deviated well Stress distribution |
