Discussion of Drilling Technology in Complex Formation of Chagandeersi Molybdenum Deposit

Abstract:

According to the breaking, leaking, collapsing and block-falling in most formations of Chagandeersi molybdenum deposit and to avoid bit sticking and burying drill, potassium humate low solid mud and relative technologies were adopted with good construction quality and high efficiency.

Key words:complex formation; core drilling; low solid mud; potassium humate mud; wall protection
