Abstract
"CONJUNTO DE HASTES DE BOMBEIO TRANSMISSORAS DE TORQUE OCAS E BICO DE VEDAçãO COM VEDAçãO E FLUXO DE FLUIDO APERFEIçOADOS". Trata-se de um conjunto de coluna impulsora alongada que compreende uma pluralidade de hastes de bombeio ocas e elementos de conexão com uma rosca central, conectados entre si e entre uma coluna impulsora posicionada na superfície de um poço de petróleo e uma bomba rotativa localizada profundamente em um poço de petróleo. Cada haste de bombeio oca tem pelo menos uma primeira extremidade que compreende uma superfície roscada fêmea interna que acopla com uma superfície roscada macho externa em um elemento de conexão, tal como um bocal. A fim de otimizar ainda mais a distribuição da tensão entre os elementos, são utilizadas roscas em formato de cone truncado não-simétricas com um afunilamento diametral diferencial. Os ressaltos de torque têm um diâmetro médio maximizado e uma área em seção transversal para resistir ao acúmulo de torque reativo na coluna impulsora. Um bocal modificado tem preferivelmente uma pequena vedação em sua extremidade livre para diminuir problemas de erosão e corrosão. Uma haste modificada pode ter uma série de furos em cada extremidade extrema, para aumentar substancialmente o fluxo do fluido extraído. Esta configuração global assegura uma alta resistência ao cisalhamento, uma baixa concentração de tensão e uma resistência surpreendente ao acúmulo de torque reativo, o que minimiza o contragiro perigoso quando o acionamento da coluna da haste de bombeio é interrompido.
