| 摘 要： | 页岩气勘探开发在中国刚刚起步，缺乏相关技术经验。为此，介绍了国外页岩气钻完井技术现状及最新进展。国外页岩气开发先后经历了直井、单支水平井、多分支水平井、丛式井、丛式水平井钻井（PAD水平井）的发展历程；目前水平井已成为页岩气开发的主要钻井方式，页岩气水平井钻井要考虑其成本，垂直井段的深度不超过3 000 m，水平井段的长度介于500～2 500 m；PAD水平井钻井利用一个钻井平台作为钻井点，先后钻多口水平井，可以降低成本、节约时间，是比较新的页岩气钻井技术；页岩气固井主要采用泡沫水泥固井技术，完井方式以套管固井后射孔完井为主。在综合分析国外页岩气钻完井技术及钻完井难点的基础上，指出国内页岩气钻井应着力解决在保持井壁稳定、预防事故、降低钻井成本、研发配套仪器和优选钻井液配方等方面存在的问题。

| Abstract: | Because shale gas exploration and development just starts its first step,neither technologies nor experiences can be available at present in China.Therefore,we first introduce the status quo of and the newest advances in the global shale gas drilling and completion.Shale gas development abroad has ever experienced the stage of vertical wells,single horizontal wells,multi-lateral horizontal wells,cluster wells,and cluster horizontal wells(PAD horizontal wells).Currently the horizontal well drilling is the ma... |
