Abstract

PISTOLAS DE PERFURAçãO EM FASE E PROCESSO DE SUA REALIZAçãO. Pistola de perfuração apresentando uma estrutura de base feita de um material que pode ser deformado. A estrutura de base inclui anéis de apoio fixados integralmente entre si através das porções de conector. As cargas com cápsula são montadas em anéis de apoio correspondentes, e cada anel de apoio sendo ajustável pela deformação seletiva da estrutura de base para confrontar uma de uma pluralidade de direções para proporcionar uma pluralidade de combinações de padrões de faseamento.DRILLING PISTOLS IN STAGE AND PROCESSING THEIR PERFORMANCE. Drill gun with a base structure made of a material that can be deformed. The base structure includes support rings that are integrally attached to each other through the connector portions. Capsule loads are mounted on corresponding support rings, and each support ring being adjustable by the selective deformation of the base structure to confront one of a plurality of directions to provide a plurality of combinations of phasing patterns.
