| 摘 要： | 在采油过程中,含油岩石的渗透率取决于岩石骨架的有效应力.在岩石内部具有一定的孔隙压力的条件下,岩石骨架的应力状态就起到主要作用.本文在分析油气井割缝前后的应力场变化的基础上,指出水力喷砂割缝本质上是改善了岩石骨架的应力状态.从而增加油层的渗透率.

| 关 键 词： | 水力喷砂割缝 有效应力 渗透率 |

| Abstract: | In the process of oil production ,the penetration of oil-content rock is determined by rock framework's effective stress.In the condition of pore pressure existing within rock,rock framework's effective stress plays an important role.According to the change of stress field before and after slit-cut,it is pointed out that Hydralic Sand-jet Slit-cut(HSS) improves rock framework's stress state and increases oil layer's penetration coefficient in the paper. |

| Keywords: | hydralic sand-jet slit-cut effective stress permeability |
