岩心钻探原理来自远古时代.古埃及曾用管钻在建造金字塔时钻过勘探浅孔,取得的岩心和钻孔样品,至今还在博物馆里展出.W.M.F.皮特里在《金字塔与神庙》(1885年)一书中考证说,管钻是用宝石镶嵌的,与过去使用的研磨粉非常相似.钻具无疑是手摇的,钻孔深度可能是以英寸计算,而非以英尺计.迪德罗特在其科学百科全书(1751年)的“艺术与商业”一章中,图示一个手摇钻棒,有数枚金刚石尖刃,曾钻进2英尺.现代岩心钻探是由莱舒特的经验不断完善而发展起来的.他是一位住在巴黎的端士
Core drilling principles come from ancient times.Egypt has drilled through the exploration of shallow holes, obtained core and drilling samples, while still in the museum with pyramid tubes.WMF Pietri in the “Pyramid & Temple” ( 1885) a book research shows that pipe is inlaid with precious stones, grinding powder used in the past is very similar to the drill is undoubtedly hand-cranked drilling depth may be calculated in inches instead of feet. Di In his chapter “Art and Business” in his Encyclopedia of Science (1751), Drotter illustrated a hand-cranked rod with several diamond blades that had drilled two feet. Schutter’s experience has been refined and developed.He is a living in Paris, the terminal
