Research and Experiment of Drilling Technology in Complicated Stratum of Molybdenum Minerals in Luanchuan of Luoyang

Abstract:

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.
