地质钻探中金刚石钻头的科学选择与合理使用

Scientific Selection and Rational Use of Diamond Bit in Geological Drilling

地质钻探工程是地质矿产勘查过程中的重要手段,金刚石岩芯钻探除必须选用相应钻机、地质管材、钻具、泥浆材料外,钻进工艺中金刚石钻头的科学选择、合理使用显得非常重要,可使金刚石钻头效能得到充分发挥,提高钻进进尺,减少金刚石钻头使用数量,提高钻探效率,从而取得最优地质钻探技术经济效果。

Geological drilling engineering is an importantmeans in geology andmineral exploration.for diamond core drilling,in addition toselect the appropriate drilling,geological pipe,drilling rig and mud materials,in the process of drilling,scientific selection and rational use ofdiamond drill isveryimportant,it can fullyplaythe effect of diamond drill and improve the drilled footage,reduces the usage quantity of diamonddrill,improve thedrilling efficiency,so as toachieve the optimal technical and economic effect of geological drilling.
