发明名称 ferramenta de enchimento e circulação com característica de controle de poço
摘要 A high-pressure casing fill-up and circulating assembly and method of use is disclosed. The fill and circulating assembly, when inserted into the uppermost portion of the casing, will allow the casing to be filled while each section of casing is added. In one configuration there can be a cup type seal that seals in the casing simply by inserting the circulator into the casing. In yet another configuration the casing circulator portion can be anchored in the casing by manipulating the setting apparatus of the circulator thus anchoring the circulator to the casing and a settable seal unit will be energized to seal between the casing and the circulator.
