Design Study Of The New Rotary Blowout Preventer

The RBOP homemade existed some problems, such as the seal's life is very short ect, so, the new type RBOP was designed on the base of collecting the information about the design, analysis, calculations and use of the RBOP inside and outside the country. And then, the Pro/E's mechanical model was firstly set up to analyze the force that the RBOP endured. This bettered the working capability of the RBOP homemade and optimized its structure. This paper provided the theory according and ways for improving the development of the RBOP homemade. The main studying work combining with the yield is following:(1) The characteristic and developing way of the RBOP were found through collecting and analyzing the information of it inside and outside the country. And the detailed developing scheme was put forward combining the technique status of the RBOP.(2) According to the working mechanism and using condition of the RBOP, the whole structure of it was fringe designed using the traditional method. And then, the 3D model of the RBOP has been drawn and assembled.(3) According to the working condition and using environment of the RBOP, the reasonable constraints and load were set up. The main parts bearing the loads, such as shell body, rotary assembly shell, center pipe and bearing pressing cover, have been carried through with finite element intension check using the structure module the Pro/E software. The results show that the strength and stiffness of the parts could meet the working needs. The safety coefficient is big.(4) Because there were some problems in the seal equipment of the RBOP, several kinds of the seal schemes were put forward. According to the working needs and manufacture technology, one kind of the seal scheme was chosen. The new seal equipment was designed to solve the problems existing in the using of the RBOP.In a word, the research work of this paper improved the general technique level of the RBOP. It was provided the development of the new product with important theory meaning and application value.
