This book comprchensivcly introduces Lhc ciriUing theory anci practice behind CCSD- l weIJ drilling,the first stage of a key national scientific cnginecring projcct of China. In addition to access to varietyofdata and information accumulated ciecade ciuring the projccfs ciecade-long operation, readers alsogain insight into stzitc-of-thc-art techniques anci most rccent achievements in China′s scientific drillingindustry. Spccifically, this Work introduces t he crilling engineering design, well site const ruction, andcquipmcnt and c-on.struction situation. It also provides a minute descscription on the new techniqucsthat werc developed f'or tackling the tcchnical difficulties, expounds in cictail the core drillingtcchiiiques for hard rock deep well, and treats ciiamond core drill bits, reaming drilling techniqucs inhard crystalline rocks, well-deviation control techniques for strong dipping strata, and much more. Insummary, this book offers a valuable resource for engineers and technic-ians who engage in scientiticdrilling and a variety of resource drilling engincering; teachers and students who are interested inthis field will also gain plentiful information.
