Abstract

En fremgangsmåte for undersjøisk boring i hvilken en borestangsammenstilling blir satt inn i et borerør mens borerøret er låst til boreriggen og borerøret er koplet til borestangsammenstillingen på en slik måte at rotasjons- og slagenergien mottatt av borestangsammenstillingen fra borehammeren er overførbar til borerøret. Videre senkes en borekrone festet til borestangsammenstillingen og en ringkrone festet til borerøret og boreriggen til havbunnen, låsingen mellom borerøret og boreriggen åpnes og borehammeren slås på for å begynne boringen ved hjelp av borekronen installert ved den nedre enden av borestangsammenstillingen og ringkronen installert på nedre enden av borerøret. Boringen fortsetter til borerøret når en forhåndsbestemt dybde ned i havbunnen, hvoretter borehammeren slås av, borerøret låses til boreriggen på en slik måte at rotasjon og dens bevegelse i forhold til boreriggen hindres, og koplingen mellom borestangsammenstillingen og borerør frigjøres. Borehammeren blir da slått på igjen og boringen fortsetter til den ønskede dybden ved hjelp av borestangsammenstillingen og borekronen.A method for subsea drilling in which a drill rod assembly is inserted into a drill pipe while the drill pipe is locked to the drilling rig and the drill pipe is coupled to the drill rod assembly in such a way that the rotational and impact energy received by the drill rod assembly from the drill hammer is transferable to the drill pipe. Further, a drill bit attached to the drill rod assembly is lowered and a ring crown attached to the drill pipe and drill rig to the seabed, the lock between the drill pipe and drill rig is opened and the drill hammer is turned on to begin drilling by the drill bit installed at the lower end of the drill rod assembly and the down drill bit installed. drill pipe. Drilling proceeds to the drill pipe when a predetermined depth into the seabed, after which the drill hammer is turned off, the drill pipe is locked to the drilling rig in such a way as to prevent rotation and its movement relative to the drilling rig, and the coupling between the drill rod assembly and drill pipe is released. The drill hammer is then turned on again and drilling continues to the desired depth by means of the drill rod assembly and drill bit.
