Reservoir Diagenesis and Quality Prediction

　　This book is meant to serve as a textbook for university students， aiming at the scientific un- derstanding of diagenesis and reservoir quality prediction， which mainly covers the majors of petro- leum exploration and petroleum engineering. We thank many postgraduate students， such as Dan Liu， Qian Li， Peijun Li， Rui Guo， Mingzhu Lei and Ao Su， for their drawing all the figures in the textbook. China University of Geosciences （Wuhan） provides the funding for the publication of this book.
