永磁直驱电动钻机在车排子地区铀矿钻探工程中的应用

Application of Electric Direct Drive Drilling Rig in Sand-stone Type Uranium Drilling Exploration in Chepaizi Area

近年来,立轴式钻机广泛应用在砂岩型铀矿钻探施工中,立轴式钻机采取机械传动,存在传动效率低、可靠性不足、动力消耗大等缺陷,在一定程度上制约了当前砂岩型铀矿钻探效率和勘探进程。为解决当前立轴式钻机自动化程度低、劳动强度高、安全环保性能低、集成化程度低、给进行程短、操作工序繁琐等问题,研制了一种适用于砂岩型铀矿钻探作业的永磁直驱电动钻机(XD-10DK)。2022年,XD-10DK电动钻机在准噶尔盆地车排子地区砂岩型铀矿的6口深孔钻探工程中获得成功应用,总钻探进尺4809.74 m。文章通过电动钻机与立轴式钻机在车排子地区施工情况进行分析,对比分析了电动钻机在施工效率、绿色勘查、安全环保、智能操作等方面的优势,指出了该型钻机存在的不足,最终认为电动钻机在砂岩型铀矿钻探工程中的应用前景广阔,是未来地质勘查钻探设备转型升级和深部钻探的理想装备。

In recent years,vertical shaft drilling rigs have been widely used in sandstone-type uranium deposit drilling.However,mechanical transmission of the vertical shaft drilling rigs brings the defects such as low transmission efficiency,insufficient reliability and large power consumption,which restricts the drilling efficiency and exploration process of sandstone-type uranium deposit to a certain extent.In order to solve the problems of low degree of automation,high labor intensity,low safety and environmental protection performance,low degree of integration,short feeding process and cumbersome operation process of the current vertical shaft drilling rig,a permanent magnet direct drive electric drilling rig(XD-10DK)was developed for sandstone-type uranium deposit drilling operation.In 2022,the XD-10DK electric drilling rig was successfully applied in the drilling project of 6 deep holes in the sandstone-type uranium moralization in the Chepaizi area of the Junggar Basin,with a total drilling depth of 4809.74 m.This paper analyzed the construction situation of electric drilling rig and vertical shaft drilling rig in Chebaizi area,compared and analyzed the advantages of electric drilling rig in construction efficiency,green exploration,safety and environmental protection,intelligent operation,etc.,the shortcomings of this type of drilling rig was pointed out and it was finally concluded that electric drilling rig has broad application prospect in sandstone-type uranium deposit exploration,and will be an ideal equipment for the transformation and upgrading of geological exploration drilling equipment and deep drilling in the future.
