Continental Scientific Drilling Project Of The Cretaceous Songliao Basin Sk 1 In China

Continental Scientific Drilling Project of the Cretaceous Songliao Basin (SK-1) in China is the first reference to provide the results of the first part of scientific drilling project at the Songliao Basin in the Daqing oil field, the largest known oil field in China. The project has two major objectives: one is to correlate the oceanic and continental records and determine the principal drivers of climate change in order to assist in future climate change predictions and its influence on the earth's environment. The second is to further test the theory of terrestrial genesis of hydrocarbons, and to explore the formation of intra-continental sedimentary basins, as many are major hydrocarbon provinces. In addition, this project provides the scientific basis for exploration of the Daqing Oilfields, which have a yearly production of forty million tons of oil. The world is entering a new exciting era to explore in which scientific drilling will provide a quantum leap in our understanding of its deep earth and history. Continental Scientific Drilling Project of the Cretaceous Songliao Basin (SK-1) in China will play an important role in promoting scientific drilling and earth system science research. Summarizes the geological background, seismic profile, and tectonic evolution of the Songliao Basin Provides detailed information on drilling technology of SK-1, which successfully obtained ~2500m core with a recovery rate of ~95% Includes detailed core information: stratigraphic charts, core photographs, and core photograph identification tables

Senior managers and Heads of Geological Survey Organizations (GSOs) from around the world have contributed a collection of papers to provide a benchmark on how GSOs are responding to national and international needs in a rapidly changing world. GSOs continue to provide key scientific information about Earth systems, natural hazards and climate change. As countries adopt sustainable development principles and the public increasingly turns to social media to find information about resource and environmental issues, the generation and communication of Earth science knowledge become increasingly important. This volume provides a snapshot of how GSOs are adapting their activities to this changing world. The different national perspectives presented converge around several common themes related to resources, environment and big data. Climate change and the UN’s Sustainable Development Goals provide an increased incentive for GSOs of the world to work in harmony, to generate knowledge of Earth systems and to provide solutions for sustainable management of the planet.

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.
