Document Type and Number:
WIPO Patent Application WO2000011306
Kind Code:
A3
Abstract:
The present invention relates to a drilling device for a drilling plant as well as to a drilling plant which can be used in exploration and production wells mainly for hydrocarbon fields both at sea or inland. This invention also relates to a method for drilling such a well. According to the present invention, the drilling device comprises a support mechanism (1) in or on which are mounted: a rotating head (2) capable of axial sliding displacement relative to the longitudinal axis of the support mechanism (1); and a rod handling device (30) which is capable of displacement or rather sliding displacement perpendicularly relative to the longitudinal axis of the support mechanism (1), and which is used for gripping the drilling rods. The support mechanism is further mounted so as to be capable of tilting movement and/or rotation at the base. The combination of the support mechanism with two drilling devices enables a continuous drilling process.
