| 摘 要： | 元页HF-1井是中石化部署在川东北元坝区块的第一口页岩气预探水平井。通过分析该井的工程地质难点,优化了三开次井身结构,优选出合理的钻井方式、钻井液体系和配套工艺措施,形成了一套适合该区块的页岩气水平井钻井技术方案。该井成功钻达目的层,完钻井深4982 m,水平位移1421.73 m,钻井周期168.88 d,平均机械钻速3.07 m/h,三开井径扩大率仅为4.82%,取得良好的应用效果,为元坝区块页岩气的勘探开发提供了技术支撑。

| Abstract: | Yuanye HF -1 is the first shale gas pre-exploration horizontal well in Yuanba block of Northeastern Sichuan. Based on the analysis on the difficult points in engineering geology, the third spud section structure was optimized ; rational drilling method, drilling fluid system and drilling process measures are selected to form a set of shale gas horizontal well drilling technical scheme suitable for this area. The well is drilled to the objective layer with drilled depth of 4982m, horizontal displacement of 1421.73mm, drilling cycle of 168.88d, average penetration rate of 3.07m/h and the three open well diameter enlargement ratio is only 4. 82%. |
