Abstract

1/1 resumo "sistema e método para a fratura de poços de óleo e gás” este relatório descritivo se refere a um sistema e método aperfeiçoados para a fratura de um poço. em uma modalidade, o sistema pode consistir de um tubo base incorporando uma entrada de inserção capacitada a alojar uma esfera de interrupção parcialmente no interior da câmara da mesma, e uma luva corrediça. a luva corrediça pode consistir de uma primeira luva contendo uma superfície interna. esta superfície interna pode conter um espaço vazio. a primeira luva pode ser manobrada para estar em duas posições. na primeira posição, o espaço vazio pode se situar em uma superfície do tubo base não incorporando uma entrada de inserção. tal posicionamento pode vir a impedir que uma esfera de interrupção deixe a câmara do tubo base. na segunda posição, o espaço vazio pode se situar sobre uma entrada de inserção. tal posicionamento pode possibilitar a presença da esfera de interrupção junto à câmara de referido tubo base dando entrada no espaço vazio.1/1 abstract "system and method for fracturing oil and gas wells this specification relates to an improved system and method for fracturing a well. in one embodiment, the system may consist of a base tube incorporating a insertion port capable of housing an interruption ball partially inside the same chamber, and a sliding sleeve. the sliding sleeve can consist of a first sleeve containing an internal surface. this internal surface can contain an empty space. the first sleeve can be be maneuvered to be in two positions. in the first position, the empty space can be located on a surface of the base tube not incorporating an insertion port. such positioning may prevent a disruption sphere from leaving the base tube chamber. na second position, the empty space can be located over an insertion entrance. such positioning can allow the presence of the interruption sphere next to the chamber of said base tube giving entry to the empty space.
