[Abstract]:The dual gradient drilling system has been developed rapidly in foreign countries and has been applied commercially to solve a series of problems in deepwater drilling. As one of the key technology equipment of double gradient drilling technology, the development of subsea mud lift disc pump is relatively slow in China. In this paper, the design of disc pump is taken as the center, and combined with the national scientific and technological project "Marine Deepwater Oil and Gas Field Development Engineering Technology" sub-project "Submarine mud lift drilling technology". The application configuration and design of subsea mud lift disc pump are simulated and studied. The following research progress is made: (1) based on the practical application requirement of disc pump in domestic double gradient system, the parameters of dual gradient drilling mud lift system are calculated. For different double gradient drilling systems, a reasonable disk pump configuration scheme is put forward. (2) A large number of simulation results are carried out by using FLUENT,Pro/E,Gambit to design the disc pump with the empirical coefficient method based on the simulation results. The design formulas of the main parameters such as the diameter of the disk pump outlet, the disk spacing, the ratio of the impeller height h and the disk spacing h / S are derived. The size program of the disc pump is programmed by VB. Numerical analysis is carried out around the influence of disk pump parameters on the external characteristics of the pump. (3) based on the pump similarity theory, the excellent hydraulic model of the disc pump is selected, and the disk pump is designed by using the similarity conversion method, and the type spectrum diagram of the disc pump is drawn. The series of disk pump is realized. (4) the motor selection of the power end of the disc pump is carried out and the scheme of sealing with magnetic coupling device is put forward.
