STRUCTURAL OPTIMUM DESIGN OF PERFORATING GUN BASED ON FINITE ELEMENT METHOD

摘要

Perforating is a very important completion operation. Shaped charge perforating occupies a position of importance in completion operation. The quality of perforating guns is hard to be guarded, multipal perforating accidents happen, and economic losses cause by unscientific design. Optimum design of blind hole and thickness on perforating guns' wall is a very meaningful job. The result is that, the best depth of blind hole is 4.2789mm, and the best thickness of wall is 9.1mm. The method mentioned above is theoretical method. The reasonable arrangement of material properties with suitable blind hole and thickness will improve performance of perforating guns. All these methods are used for reference to manufacture and scientific research of perforating guns.
