中文摘要:介绍了汶川地震断裂带科学钻探项目中深孔取心钻进方法应用的演变过程。从最初设计的螺杆马达-液动锤取心钻进方法变化到顶驱-绳索取心钻进方法,再变化到螺杆马达-液动锤-长半合管取心钻进方法。用于该项目的深孔取心钻进方法经历了一系列变化,促使这些变化发生的原因是地层条件以及取心技术的改进和发展。 |

Abstract:This article introduces the evolution process of the core drilling methods used in Wenchuan Earthquake Scientific Drilling Project. From PDM/hydro-hammer coring method to top-drive/wire-line coring method and finally to PDM/hydro-hammer/long split barrel coring method, the coring methods used in this project underwent a series of changes. The main reasons for these changes are formation conditions, coring technology improvement and the development. |
