摘要: XYHF-1井是川西地区第1口页岩气勘探水平井，在其钻井过程中存在机械钻速低、井身质量难以控制、钻井液选择困难、井控风险大、井壁稳定性差等难题。在深入分析该井钻井难点的基础上，重点阐述了井身结构优化、井眼轨迹控制、钻具组合优化、安全钻进和储层保护等关键钻井技术及其应用效果，并简要介绍了旋转导向钻井、油基钻井液和滑套固井技术在该井的应用情况。全井钻井周期253.17 d，平均机械钻速1.6 m/h（含直导眼段），全井井径扩大率小于12%，上部井段最大井斜为0.87°，施工效果较好。应用效果表明，合理的井身结构和井眼轨道优化设计，是保证浅层水平井顺利实施的前提；加强摩阻扭矩预测、采用安全钻进措施和良好性能的钻井液，是预防井下复杂情况和安全钻进的重要保证，该井的顺利完钻，为同类井提供了实践经验。

Abstract: XYHF-1 well is the first shale gas prospecting horizontal well in west Sichuan. However, there are many difficulties in its drilling process, such as the low ROP, difficulty in controlling the well body quality, difficulty in selection of drilling fluid, high risk of well control and poor stability of well wall. This paper mainly elaborates the key drilling technologies and application effects, such as optimizing well structure, controlling wellbore track, optimizing drilling tools, safely drilling and reservoir protecting technology based on the analysis of drilling difficulties. At the same time, this paper briefly introduces application of some new technologies in this well, such as rotary guide drilling, oil-based drilling fluid and sleeve cementing techniques. The drilling cycle time is 253.17d for full hole, average ROP is 1.6m/h (including the pilot hole), the enlargement rate of full hole diameter is below 12%, and the maximum well deviation of the upper part is 0.87°, the construction effect is good. The application results show that reasonable well structure and borehole trajectory design is the basic premise of smooth drilling of shallow horizontal wells; and strengthening the prediction of friction and torque and using safety measures and good performance drilling fluids are the important guarantee for the safety drilling. The successful finish drilling of this well provides practical experience for similar wells.
