近几年来,由矿业主承受的降低其产品成本的压力,已反应给钻机制造厂,要求他们制造以一定费用能钻进更多米孔的钻机。几乎所有制造厂都已采用计算机辅助设计,把它作为提高钻机设计效率的一个有影响的因素。在大型钻机上利用机载计算机向操作
The pressure on mining owners to reduce the cost of their products in recent years has been echoed to rig manufacturers asking them to build rigs that can drill into more meters at a cost. Almost all manufacturers have adopted computer-aided design as an influential factor in improving rig design efficiency. Use of onboard computers for operation on large rigs
