Abstract
"MéTODO PARA PERFURAR E TRATAR MúLTIPLOS INTERVALOS DE UMA OU MAIS FORMAçõES SUBTERR‰NEAS INTERCEPTADAS POR UM FURO DE POçO, E, SISTEMA DE TRATAMENTO POR ESTìMULO, E APARELHO PARA USO NA PERFURAçãO E TRATAMENTO DE MúLTIPLOS INTERVALOS DE UMA OU MAIS FORMAçõES SUBTERR‰NEAS INTERCEPTADAS POR UM FURO DE POçO". A invenção provê um aparelho e método para perfurar e tratar múltiplos intervalos de uma ou mais formações subterrâneas (86) interceptadas por um furo de poço pelo desenvolvimento de uma montagem de furo de fundo tendo um dispositivo de perfuração (134) e pelo menos um mecanismo de vedação (120) dentro do mencionado furo de poço. O dispositivo de perfuração (134) é usado para perfurar o primeiro intervalo a ser tratado. Depois, a montagem de furo de fundo é posicionada dentro do furo de poço de modo que o mecanismo de vedação (120), quando atuado, estabeleça uma vedação hidráulica no furo de poço para forçar positivamente o fluido entrar nas perfurações (230, 231) correspondentes ao primeiro intervalo a ser tratado. Um fluido de tratamento é, depois, bombeado pelo furo de poço e para as perfurações (230, 231) criadas no intervalo perfurado. O mecanismo de vedação (120) é liberado, e as etapas são, depois, repetidas por tantos intervalos quantos desejados, sem remover a montagem de furo de fundo do mencionado furo de poço."METHOD FOR DRILLING AND HANDLING MULTIPLE INTERVALS OF ONE OR MORE SUBMERGIAL FORMATIONS INTERCEPTED BY A WELL HOLE, AND STIMULUS TREATMENT SYSTEM, AND APPARATUS FOR USE IN MULTIPLE OR INTERVAL MACHINES AND DRILLING INTERCEPTED BY A HOLE ". The invention provides an apparatus and method for drilling and treating multiple intervals of one or more underground formations (86) intercepted by a wellbore by developing a bottom hole assembly having a drilling device (134) and at least one mechanism. (120) inside said well bore. The piercing device 134 is used to pierce the first gap to be treated. The bottom hole assembly is then positioned within the wellbore so that the sealing mechanism (120), when actuated, provides a hydraulic seal in the wellbore to positively force fluid into the boreholes (230, 231). corresponding to the first interval to be treated. A treatment fluid is then pumped through the wellbore and into the bores (230, 231) created in the borehole. The sealing mechanism (120) is released, and the steps are then repeated for as many intervals as desired without removing the bottom hole assembly from said well hole.
