| 中文摘要:焦页60-5HF井是处于焦石坝构造东南翼的一口页岩气水平井，该井设计井深5290 m，井斜69.30°，垂深3945.04 m，闭合位移2513.99 m。在实际施工中为确保水平段在储层中延伸，经多次调整后，最终完钻井深5235.00 m，井斜81.8°，垂深3820.56 m，水平位移2509.53 m，水平段长1775.00 m，为重庆涪陵工区垂深最深的一口水平井。实际施工中为保证井眼轨迹在储层中穿行，克服了井下工具抗高温、水平段摩阻大、定向托压、井眼轨迹防碰等诸多问题，成功完成了该井的施工任务，为该地区施工超深井提供了可借鉴的经验。 |

| Abstract:Jiaoye 60-5HF is a horizontal shale gas well in southeast wing of Jiaoshiba structure with designed depth of 5290m, inclination angle 69.30° , vertical depth of 3945.04m and closed displacement 2513.99m. Several adjustments were made to overcome high temperature, large friction drag, backing pressure and well trajectory intersection to ensure the horizontal section extension along the reservior during the construction; the drilling depth was 5235.00m. It was a horizontal well with the deepest vertical depth in Fuling work area with inclination angle 81.8°, vertical depth 3820.56m, horizontal displacement 2509.53m and horizontal section length 1775.00m. |
