摘要: 高原钻探难度大，相较于低海拔钻探面临着更多问题和风险。高原高寒地区的钻探设备主要通过现有设备进行改造完成。本文基于某高原高寒钻探现场应用遇到钻探设备动力不足、高原高寒润滑不充分、以及人员保障方面遇到的问题，开展钻探设备的高原高寒适应性改造。结合发动机动力下降30%的问题和高原其他设备改造电力需求，将发电机增加到8 台，同时优选合适的润滑油增加设备保温装置。针对高寒、缺氧和水源质量差的问题，建立保温功能的沙漠公寓屋，同时屋内增加氧气供给设备和弥散式供氧面板，采用渗透式水源净化装置净化水源。最终解决高原钻探设备和人员面临的低温、低氧和低气压等问题，为我国高原地质资源勘探提供技术支持。Abstract: Comparing low altitude drilling, plateau drilling is more challenging and fraught with dangers. In plateau and cold climates, equipment modification is the primary means to complete drilling operations. This article is focused on the different issues that arise when drilling in a field on a particular high-altitude cold plateau which include low equipment power, inadequate lubrication and personnel support, in addition, the adaptation of drilling equipment to cold and plateau conditions is implemented. The number of generators will be expanded to eight units as the 30% loss in engine power and the reform requirement of other devices ,in the meantime, appropriate lubricants will be chosen concurrently to add equipment insulating devices. An apartment building with thermal insulation was constructed in the desert to address the issues of extreme cold, oxygen deprivation, and low water quality. Diffuse oxygen supply panel and oxygen supply equipment are also added, at the same time, the water was purified using a permeable water source purification system. By the above mesures, the issues of low temperature, low oxygen, and low pressure that workers and equipment encountered are resolved,which will support technical assistance for the exploration of geological resources on the plateau.
