| 摘 要： | 利用地层倾角测井资料分析了元坝地区地应力方向,该区地应力方向为近东西向;在此基础上,分析了地应力方向与水平井井壁稳定性的关系,研究表明水平段方位沿着水平最大地应力方向,坍塌压力达到最低、破裂压力较高,井壁稳定性好。

| Abstract: | The paper uses dip log data analysis of stress direction of the Yuanba region.The stress direction is near east-west orientation.On this foundation,the relationship of stress direction and horizontal well borehole stability is anaylzed.When horizontal orientation along the maximum horizontal stress direction,collapsing pressure reaches a minimum and fracture pressure is higher and borehole stability is best. |

| Keywords: | horizontal well stress direction borehole stability |
