【摘要】 本文介绍了根据国际石油勘探作业对山地钻井作业设备的需求分析,研制开发出的HY-20G和HY-40F山地钻机。HY-20G山地钻机重量轻,搬迁运输便捷,适合于井深在20m以内的泥岩、砂岩地表的物探钻井作业。HY-40F钻机在保持原HY-40钻机钻井能力不变的情况下,总重降低了18%,最大单件重量降低了33%。更多还原

【Abstract】 Based on the requirement analysis of mountainous drilling of international seismic operation,new type of HY-20G and HY-40F portable drill rigs were developed.HY-20G portable drill rig is lighter in weight and easier to move at working site.It is suitable for the seismic drilling on mudstone and sandstone terrain.The total weight and maximum single module weight have been reduced by 18% and 33% respectively while keeping the same drilling capacity with original HY-40 drill rig.更多还原
