摘　　要：井眼净化问题是深层水平井钻井的难点和关键。结合X10-1H井实际情况,分析了钻井液性能、井径扩大率、机械钻速、钻具转速、钻井液排量等对井眼净化的影响。提出优化钻具结构、合理调整钻井液性能、加强短程起下钻、选择合理的钻进方式和钻井速度以及研制破坏岩屑床新工具等井眼净化技术,这些技术在X10-1H深井钻井过程中应用后,取得了良好效果。The issue of hole cleaning of horizontal wells in deep zones is difficult and important.Combined with the pracitcal situatin of X10-1 H well,the drilling fluid properties and other factors that may have an influence on hole cleaning have been analyzed.In the end,the paper put forward the hole cleaning technique for horizontal wells which covers the following issues:the structure of drilling tools should be optimized, the properties of drilling fluids should be adjusted, the drilling design and drilling speed should be properly selected and etc,and the application proved to provide guidance for the drilling of horizontal wells in deep zones.
