钻参仪参数检测原理及传感器选型安装

深部和外围找矿工作的不断发展,需要研制出新型深孔钻机及其配套的钻探参数监测系统。全液压动力头岩心钻机将是未来深部钻探的主力钻机,CUG-2钻参仪是中国地质大学研制的与2000 m全液压动力头岩心钻机配套的钻探参数监测系统。介绍了CUG-2钻参仪的设计特点和检测参数,重点介绍了与常规转盘式、立轴式钻机不同的参数检测原理及其传感器选型安装,包括孔深、钻速、扭矩、功率和出口流量等。

Parameter Detection Principle of CUG-2 Drilling Parameter Monitor and Lectotype Installation of the Senor

With the continuously development of deep and peripheral prospecting,a new type of deep-hole drilling rig matched with monitoring system of drilling parameters is required,and all hydraulic-top head core drilling rigs will be the main drilling rigs for deep drilling in future.CUG-2 monitoring system of drilling parameter monitor was designed by China University of Geosciences to match the 2000m all hydraulic-top head core drilling rig specially.This article introduced the design characteristics and testing parameters of CUG-2 system and emphatically introduced the parameters detection principle which was different to the principles for normal rotary drilling and shaft-drilling rigs as well as lectotype installation of sensors,including hole depth,drill speed,torque,horsepower and flow out rate.
