Abstract
''PROCESSO E NAVIO PARA PERFURAçãO NO SUBSOLO''. A presente invenção refere-se a um processo para perfuração no subsolo, por exemplo por petróleo ou gás, a partir de um navio, uma cabeça perfuradora sendo usada para a perfuração; a extremidade superior da coluna de perfuração sendo afixada, com o auxílio de dispositivos de levantamento, a uma torre ou mastro de perfuração que é colocada sobre o navio; os dispositivos de levantamento sendo munidos de dispositivos de acoplamento para acoplamento sobre a coluna de perfuração e com dispositivos de mola para amortecer os movimentos do navio com respeito à coluna de perfuração como um resultado da ação da marola e das ondas sobre o navio; e a coluna de perfuração sendo essencialmente circundada entre o navio e o fundo por uma coluna montante que está afixada ao fundo, em cujo processo a extremidade superior da coluna de perfuração ou os dispositivos de acoplamento são conectados, com o auxílio de dispositivos tensores, com a extremidade superior da coluna montante, sendo possível mover a extremidade superior da coluna de perfuração, com o auxílio dos dispositivos tensores, contrariamente à ação dos dispositivos de mola.'' PROCESS AND SHIP FOR DRILLING IN THE UNDERGROUND ''. The present invention relates to a process for drilling underground, for example by oil or gas, from a vessel, a drilling head being used for drilling; the upper end of the drilling column being attached, with the aid of lifting devices, to a drilling tower or mast that is placed on the ship; the lifting devices being provided with coupling devices for coupling on the drill string and with spring devices to cushion the movements of the ship with respect to the drill string as a result of the action of the wave and waves on the ship; and the drilling column being essentially surrounded between the ship and the bottom by an upright column that is attached to the bottom, in which process the upper end of the drilling column or the coupling devices are connected, with the aid of tensioning devices, with the upper end of the upright column, being possible to move the upper end of the drilling column, with the aid of the tensioning devices, contrary to the action of the spring devices.
