| 中文摘要:在印尼塔里阿布铁矿项目岩心钻探施工中，其地层既具有泥岩、页岩、粘土岩的遇水膨胀、坍塌，又有凝灰岩、火山灰岩的遇水溶解及硅化石英岩的“打滑”，以及粉状铁矿取心难的特点。易出现卡钻、粘钻等孔内事故。通过大胆的探索，形成了针对该地区岩心钻探施工的一套施工工艺，取得了良好的钻探技术效果。详细介绍了印尼塔里阿布岛铁矿项目岩心钻探施工技术。 |

| Abstract:During the core drilling operation in the iron mine project of Taliabu Island, Indonesia, the formations drilled were with the trait of hydrophilic expansion and collapse as mudstone, shale and clay rock; with the trait of hydrophilic dissolution as tuff and ash rock; with the trait of “slipping” as chloride quartzite, and with the trait of difficult coring as fine iron ore. Downhole accidents like jamming, sticking and so on easily happened. Through bold exploration, a set of specific core drilling procedures in this area was developed with good technical results. The paper introduced the core drilling technology for this project in detail. |
