Abstract

"CONJUNTO DE PISTOLA DE PERFURAçãO PARA UTILIZAçãO EM UM POçO SUBTERRâNEO E MéTODO DE OPERAçãO DE UM CONJUNTO DE PISTOLA DE PERFURAçãO". Um conjunto de pistola de perfuração que inclui pelo menos um componente que é construído a partir de um material composto e que é impermeável junto aos fluidos da cavidade de poço. Os componentes podem incluir o condutor externo e/ou o tubo de carregamento de uma pistola de perfuração, a tubulação de conexão de um mecanismo de liberação de pistola, e o conector de pistola usado para fixar as pistolas de perfuração adjacentes. O material composto é designado para forte estilhaçamento diante do impacto dinâmico. O componente é tornado impermeável junto aos fluidos de cavidade de poço através da inclusão de uma luva impermeável nos mesmos. A luva impermeável pode ser aglutinada junto a superfície interna ou externa do componente ou pode ser embutida no interior do componente. Uma vez que ocorre o estilhaço diante do impacto dinâmico, o componente composto fragmenta-se em pedaços pequenos diante da detonação da pistola de perfuração."DRILLING PISTOL SET FOR USE IN AN UNDERGROUND WELL AND METHOD OF OPERATING A DRILLING PISTOL SET". A drill gun assembly that includes at least one component that is constructed from a composite material and is impermeable to the well cavity fluids. Components may include the outer conductor and / or the loading tube of a drill gun, the connecting tubing for a gun release mechanism, and the gun connector used to secure the adjacent drill guns. The composite material is designed for strong shattering in the face of dynamic impact. The component is made impermeable to the well cavity fluids by including an impervious glove in them. The waterproof glove can be bonded to the internal or external surface of the component or can be embedded inside the component. Once the shatter occurs in the face of dynamic impact, the composite component breaks up into small pieces when the drill is detonated.
