| 摘 要： | 水力深穿透射孔技术的成孔结构、渗流条件与多分支水平井比较接近,可通过多分支水平井产能公式来研究水力深穿透射孔井的产能。分析可知,水力深穿透射孔井的产能受射孔孔径、孔长、孔数、表皮系数的影响。实践证明,水力射孔井能够起到改善完井效果、降低表皮系数的作用。

| Abstract: | The channel structure,flow situation of water-power deep perforation well is similar to multiple branched horizontal well,so, the productivity of it is calculated through the productivity formula of multiple branched horizontal well, by analysis of it, the productivity of water-power deep perforation well is affected by perforation radius,length,diameter and skin factor. Water-power deep perforation well can ameliorate perforation completion and reduce skin factor of pollution during drilling. |

| Keywords: | water perforation branched horizontal well productivity skin factor |
