这是一个真实的故事。本世纪８０年代初，改革开放刚刚开始，我国从国外引进了石油钻井新技术，包括高压喷射钻井、高效钻头、优质泥浆。同过去几十年应用的钻井技术相比，这套新技术更加科学、先进。比如，过去我们的钻头硬度不够，泥浆质量不好，打钻费劲不说，打不了几... this is a true story. In the early 1980s, just after the reform and opening up, China introduced new oil drilling technologies from abroad, including high-pressure jet drilling, high-efficiency drilling bits and high-quality mud. Compared with the drilling technology used in the past decades, this new technology is more scientific and advanced. For example, in the past, our bit hardness is not enough, the quality of mud is not good, drilling hard to say, can not play a few ...
