This thesis combines Liaohe Petroleum branch of the jet pump wells the sand discharge system design and software development topics for new methods of crude oil production in the proposed new jet pump wells desilting process, on the basis of experimental studies, single phase turbulent jet jet pump field characteristics, the basic characteristics of the liquid-solid two-phase jet pump, the numerical calculation, and as a basis, combined with practical engineering applications, the development of the oil well jet pump sand discharge system design applications. The main purpose of the paper is divided into seven chapters: The first chapter describes the background and intent of this thesis, the details of the research status quo at home and abroad on the jet pump and a jet pump applications in various fields at home and abroad, proposed thesis research . Second chapter, on the basis of the problems of jet pump basic theoretical research, the basic characteristics of the jet pump comprehensive, systematic study, and on this basis, the jet pump cavitation jet pump export pressure stability derived theoretically optimal area ratio. Further study and analysis of the energy distribution of the internal flow field of the jet pump and its influencing factors, and provide a reliable basis for efficient jet pump. Chapter III, on the basis of the experimental study of single-phase jet pump turbulent jet field numerical calculation, obtained the basic characteristics of turbulent jet field, and focuses on the throat pipe diameter of jet pump turbulent jet field. The fourth chapter, the basic characteristics of the liquid-solid two-phase jet pump numerical simulation, obtained the basic characteristics of the jet pump in the transportation of solid particles, research and analysis of the solid-phase particle diameter, the parameters on the initial concentration of the solid phase the basic characteristics of the jet pump. The research results have laid a theoretical foundation for the engineering design and application. Chapter 5, and improve the basic characteristics of the jet pump experimental apparatus and experimental study of the basic characteristics of the jet pump, the experimental results to verify the numerical results of the jet pump. Chapter VI, developed jet pump wells sand discharge system design application software, and for practical engineering applications, and achieved good results. Chapter VII of this research work, the results are summarized and looking forward to the future direction of research.
