摘要
Luanchuan polymetallic mineralization area is located in a large fracture belt containing 4 large fractures across with the main and secondary structures well developed. The borehole collapsing and difficult coring come into being. Good results were got by improving the property of washing fluid, using JS122 wire-line coring tool and searching for bit adaptability for formation.
