Application of XD-40 drilling rig in geothermal exploration well construction in Xiongan New Area

摘要:

深部矿产资源勘查技术装备XD-40型钻机应用于雄安新区地热勘探井施工，圆满完成了D13井钻探任务，完钻井深2506.14 m，完钻口径152.4 mm。本文主要从工程概况、设备特点、施工情况、事故处理等方面，介绍D13井的施工情况，总结了XD-40型钻机的总体性能、事故处理、多工艺性、能耗等方面的表现。验证了XD-40型钻机的能力及安全可靠、智能控制、节能环保方面的优越性，可应用于井深2500~2800 m的地热井施工。

Abstract:

XD-40 drilling rig， the technical equipment for deep mineral resources exploration， has been applied to the construction of geothermal exploration wells in Xiongan New Area， and successfully completed the drilling task of Well D13， with the drilling depth of 2506.14m and the drilling diameter of ?152.4mm. This paper mainly introduces the construction of D13 well from the aspects of project overview， equipment characteristics， operations and accident treatment， and summarizes the performance of XD-40 in overall performance， accident treatment， multi-process adaptability， and energy consumption. It has been proved that XD-40 drilling rig has the advantages of safety， reliability， intelligent control， energy saving and environmental protection， and can be applied to the construction of geothermal wells with depth of 2500~2800m.
