摘要
Process for the exploitation of natural resources under the seabed, and system for the drilling of a well on the sea bed ".The invention relates to a process for the exploitation of natural resources under the seabed.Where a vessel surface (1) is set almost geoestacionariamente by means of a tower (3) rotating in relation to the vessel (1) around a vertical axis (4) and having cables of amarrau00e7(7) that will extend to the sea bed, and where the drilling and / or production of a shaft (6) on the sea bed (2) is executed from the vessel (1).The drilling hole (6) is executed from a section of the perforation (5, 12) in the vessel (1) at a distance from the axis of rotation (4) of the tower (3).Drilling is performed using a drilling column through an ascending tube (13) which extends from the sea bed (2) to the section of the perforation (5, 12)The ascending tube (13) which can be interrupted and blocked (14) between the reader of the sea (2) and the vessel (1).By means of manipulation (stretching and reduction of tension) of mooring cables (7), is kept in the position, the vessel (1) is held in position.So that the drilling tower (5) is maintained almost geoestacionariamente in relation to the shaft (6) during drilling operations.The invention also relates to a system for the drilling of a well on the sea bed, comprising a vessel surface (1),The means for maintenance of the vessel (1) in a desired position above a point on the sea bed (2),These means comprise a tower (3) rotating in relation to the vessel (1) around a vertical axis (4) and which can be anchored to the sea bed (2) by means of a plurality of cables of theMarrau00e7u00e3o (7), and an ascending tube (13) which extends from the sea bed (2) to the vessel.Whereby the well can be drilled with a drilling column from a drilling tower (5) in a section of drilling on the vessel (1).The tower (3), and the section of drilling (12) are arranged so as to be spaced in longitudinal direction of the vessel.The ascending tube (13) is disposed in a circular sector around the tower (3), which is free of mooring cables (7) and possible ascension pipes of production (16).The tower (3) consists of a means for manipulation (stretching / reduction of the voltage) of mooring cables.The ascending tube (13) is capable of being broken and blocked (14) between the sea bed (2) and the vessel (1).
