    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现状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 plateau drilling to low altitude drilling, plateau drilling is more challenging and fraught with dangers. In plateau and cold climates, equipment modification is the primary means of completing drilling operations. This article is focused on the different issues that arise when high-altitude cold drilling is applied in the field on a particular plateau. These issues include inadequate lubrication in high-altitude cold plateaus, issues with people support, and inadequate drilling equipment power. Implement the adaptation of drilling equipment to cold and plateau conditions. The number of generators will be expanded to eight units dependent on the power consumption of other devices in order to address the issue of the 30% loss in engine power. Depending on the power requirements of other equipment transition on the plateau, the number of generators will be expanded to eight units. Appropriate lubricants will be chosen concurrently to boost equipment insulating devices. An apartment building with thermal insulation was constructed in the desert to address issues with extreme cold, oxygen deprivation, and low water quality. The home also received a diffuse oxygen supply panel and oxygen supply equipment at the same time, and the water supply was purified using a permeable water source purification system. At last, it will give technical assistance for the exploration of geological resources on the plateau in China, as well as resolve the issues with low temperature, low oxygen, and low pressure that workers and equipment must deal with plateau drilling.
