Reverse Modeling Analysis and Design on Rubber Sealing Element in Spherical BOP

Spherical BOP is one of crucial equipments in snubbing operation well in petroleum industries, with its core element of rubber sealing element, the connection between the spherical surface of metal skeleton and the rubber is irregular surface, it is difficult to determine the model by manual surveying and mapping. The paper put forward a design method on spherical bop rubber sealing element with the reverse engineering technology. Through the analysis of the reverse surveying and mapping basic requirements on spherical bop rubber sealing element, determined its data acquisition path and process spherical, and puts forward some solutions to the data merger, data transfer and the method of pixels processing.
