This book comprehensively introduces the drilling theory and practice behind CCSD-1 well drilling, the first stage of a key national scientific engineering project of China. In addition to access to variety of data and information accumulated decade during the project’s decade-long operation, readers also gain insight into state-of-the-art techniques and most recent achievements in China’s scientific drilling industry. Specifically, this work introduces the drilling engineering design, well site construction, and equipment and construction situation. It also provides a minute description on the new techniques that were developed for tackling the technical difficulties, expounds in detail the core drilling techniques for hard rock deep well, and treats diamond core drill bits, reaming drilling techniques in hard crystalline rocks, well-deviation control techniques for strong dipping strata, and much more. In summary, this book offers a valuable resource for engineers and technicians who engage in scientific drilling and a variety of resource drilling engineering; teachers and students who are interested in this field will also gain plentiful information. Prof. Da Wang, the former deputy director of China Geological Survey, was the director of the Engineering Centre, chief engineer and drill-site general director of China Continental Scientific Drilling Project.

The origin of the mythological version of I Ching put together by the culture pioneer Fu Xi, after studied the patterns of nature in the sky and on the earth: the markings on birds, rocks, and animals, the movement of clouds, the arrangement of the stars. He discovered that everything could be reduced to eight trigrams, each composed of three stacked solid or broken lines, reflecting the Yin and Yang, the duality that drives the universe. The trigrams themselves represented respectively, heaven and earth; thunder and wind; water and fire; mountain and lake (see illustration inside the book). In here, all the Yin-Yang bodies are opposite, complementary, symmetrical and balanced. There is an instinctive relationship of attraction, repulsion and neutralization among them. The Yin-Yang ratio could further develop into a concept of methodology, or scenario represented by an image, trigram or hexagram system that could be accurately calculated while the number of Yin-Yang ratio of each Yin-Yang model in the universe could be deduced. In this book, for the first time, based on the principles of the Yin-Yang ratio, author use it to explain the great discovery in science; such as the DNA and the origin of the universe.
