Abstract

"SISTEMA E MéTODO PARA O CONTROLE DAS PRESSõES DE OPERAçãO EM UM FURO DE POçO SUBTERRâNEO". Um furo de poço inclui um elemento tubular, um elemento de vedação para vedação de um espaço anular entre o elemento tubular e o furo de poço, uma bomba para o bombeamento de materiais fluidos para o elemento tubular, e um regulador de pressão automático para a liberação de forma controlada de materiais fluidos pressurizados para fora do espaço anular. Um sistema e um método monitoram a pressão de operação no elemento tubular e comparam a pressão de operação real com uma pressão de operação desejada. A diferença entre a pressão de operação real e a pressão de operação desejada, então, é processada para o controle da operação do regulador de pressão automático para, desse modo, se sangrarem de forma controlada os materiais fluidos pressurizados para fora do espaço anular, desse modo criando-se uma contrapressão no furo de poço.
