| 中文摘要:羌资-14井地质浅钻工程为地质参数井，设计井深1200 m，要求全井取心。存在破碎地层取心困难、钻遇小型“溶洞”地层漏失、冬季施工困难等问题。此外，井位高海拔无人环境也给施工后勤供应带来难度。通过采取特种取心工具、水泥灌浆封孔堵漏、加热电阻丝包裹吸水管加热等工艺技术措施以及针对性的施工组管理措施，有效地解决了钻井技术难题和后勤供应问题。为该区域及类似区域油气地质调查钻井施工提供了参考。 |

| Abstract:Shallow drilled Qiangzi well-14 is a geological parameter well with designed depth of 1200m, the whole coring was required. There were difficulties of coring in broken formation, drilling in karst formation and construction in winter and what’s more, the high altitude unmanned environment also brought difficultie to the construction logistics supply. By taking special coring tools, cement grouting plugging, heating suction pipe with winding resistance wire as well as targeted construction management measures, the above difficulties have been effectively solved. |
