The Discuss and Research with Drilling Technology in Complex Formation in Ruo Ergai Area

Abstract:

Uranium deposits in ruoergai, Northwest Sichuan plateau high stratum "leak, collapse, oversized, hole deviation ", is typical of the "deadly venoms and taste", rare domestic drilling complex formations. Through careful analysis and research, the technology improvement, of high quality mud system, successfully crossed the nearly 500 metres of carbonaceous rocks; continuous whipstocking successfully implement deep-hole directional drilling, provided a basis for hole in Quito, under complex formation.
