我国是凿井技术发明和使用最早的国家,始于黄帝。远在十九世纪初,我们的祖先就利用纲绳钻进的方法,凿造了一千米的井眼。当年,造这样深的井,虽非绝后,确属空前;即使从现代的造井技术水平来看,也是惊人的。直到目前,纲绳——冲击钻进仍是钻凿直井最常用的方法。为了防止井壁坍塌,国外大多来用套管加固井壁,需要大量纲材。在大跃进的年代 China is the earliest country invented and used for drilling technology, starting with the Yellow Emperor. As far back as the beginning of the 19th century, our ancestors drilled a kilometre of wellbore using the method of drilling through the rope. In those years, the deep wells that were created were nevertheless unprecedented, and they were amazing even from the perspective of modern well-making technology. Until now, wireline-impact drilling is still the most common method for drilling vertical wells. In order to prevent collapse of the borehole wall, foreign countries mostly use casing to reinforce the borehole wall and require a large number of profiles. In the era of the Great Leap Forward
