Abstract

MÉTODO PARA CONTROLE DE PRESSÃO DE POÇO É descrito um método de controle de pressão de poço que pode incluir regular a pressão em um furo de poço, operando uma bomba de sucção que extrai fluido de uma coroa circular formada entre uma coluna de perfuração e o furo de poço, o fluido entrando na bomba de sucção próximo à superfície da terra. Um outro método de controle de pressão de poço pode incluir regular a pressão em um furo de poço, operando uma bomba de sucção que aplica pressão de sucção em uma coroa circular formada entre uma coluna de perfuração e o furo de poço. Um sistema de perfuração de poço pode incluir uma bomba de sucção posicionada próxima à superfície da terra. A bomba de sucção pode receber fluido que sai de uma coroa circular formada entre uma coluna de perfuração e um furo de poço.METHOD FOR CONTROLLING WELL PRESSURE A method of controlling well pressure is described which may include regulating the pressure in a wellbore by operating a suction pump that draws fluid from an annulus formed between a drillstring and the borehole. well, the fluid entering the suction pump close to the surface of the earth. Another method of controlling wellbore pressure may include regulating the pressure in a wellbore by operating a suction pump that applies suction pressure to an annulus formed between a drill string and the wellbore. A well drilling system may include a suction pump positioned close to the earth's surface. The suction pump can receive fluid exiting an annulus formed between a drill string and a wellbore.
