摘要
针对洛阳栾川钼矿复杂地层情况,对其钻进工艺进行研究,重点论述了全孔反循环钻进技术和跟管钻进技术的工作原理以及钻具组合、实验设备、野外工作情况及野外试验成果。生产试验证明,潜孔锤跟管钻进、潜孔锤反循环钻进技术的组合型应用对该矿区复杂地层的钻进更加有效。
According to the complicated stratum of molybdenum mineral in Luanchuan of Louyang, drilling technology was analyzed. The paper mainly discussed the working principle of full-hole reverse circulation drilling ＆ drilling with casing technology, the drill assembly, experimental equipment, field work and field experimental result. It was proved that the combined application of DTH drilling with pipe and DTH reverse circulation drilling was more effective in this area.
