油气井工程多相流动（英文版）

Multiphase Flow in Oil and Gas Well Engineering (English Version) is a book that provides solutions to the complex multiphase flow analysis and calculation problems in oil and gas drilling and production wells. The book discusses the flow pattern transformation mechanism, flow pattern discrimination criteria, and multiphase flow models involved in multiphase flow calculations. The discussed seven parts of the book allow readers to understand the multiphase flow models considering oil-gas and hydrate phase change. They can also learn about the application of the model in the design and calculation of hydraulic parameters for onshore and offshore drilling wellbore pressure control. In addition, the book discusses the application of multiphase flow models in underbalanced drilling, including gas drilling, annulus injection-aerated drilling, and drill pipe injection-aerated drilling. The book also gives new research results for acid gas invasion and hydrate phase change during drilling.The book provides a more comprehensive understanding of multiphase flow models, improving the existing model for complex multiphase flow calculations in the oil and gas industry. It showcases a new achievement in the research of the fundamental theory of petroleum engineering. The author of the book is the main contributor to the multiphase flow model and gas-liquid flow pattern transformation mechanism in the book.This book is suitable for graduate students and researchers who engage in the study of oil and gas multiphase flow dynamics, reservoir engineers, drilling engineers, production engineers, and well servicing engineers. It is a valuable reference book for professionals in the oil and gas industry, and it is worth recommending it to them.
