Abstract
A drilling machine for a drilling rig and a drilling rig which can be used for exploratory drillings and producing wells, particularly in hydrocarbon deposits, both onshore and offshore. The drilling machine includes a base, on or in which a top drive is displaceable axially to the longitudinal axis of the base and a pipe-handling apparatus which is movable, especially by sliding, perpendicularly to the longitudinal axis of the base and which grips the drilling pipe. The base is pivotably and/or rotatably mounted in the region of the foot, and it is possible for a virtually continuous drilling process to be carried out using a combination of two drilling machines.
Claims40
A drilling machine, comprising:
- a base having a foot and a longitudinal axis;
- a top drive arranged one of on and in the base so as to be displaceable axially to the longitudinal axis of the base;
- and a pipe-handling apparatus integrated in the base so as to be movable perpendicularly to the longitudinal axis of the base and which grips a drilling pipe, the base being pivotably and rotatably mounted in a region of the foot such that the base is pivotal from a substantially vertical position toward a horizontal position and is rotatable about the longitudinal axis of the base in the substantially vertical position.
A drilling apparatus as defmed in claim, 1, wherein the drilling machine is configured to be horizontally slidable.
A drilling rig, comprising at least two drilling machines arranged so as to be alternatingly one of movable, rotatable and pivotable over a center line of a well, each of the drilling machines including a base having a foot and a longitudinal axis, a top drive arranged one of on and in the base so as to be displaceable axially to the longitudinal axis of the base, and a pipe-handling apparatus arranged one of on and in the base so as to be movable perpendicularly to the longitudinal axis of the base and which grips a drilling pipe, the base being at least one of pivotably and rotatably mounted in a region of the foot.
A method for sinking a well, comprising the steps of:
- a) rolling a pipe onto a base of a drilling machine, a top drive being in an upper position and grippers of a pipe-handling apparatus being moved into the base;
- b) gripping the pipe with the pipe-handling apparatus as soon as the pipe is lying in an intended position o the base;
- c) subsequently raising the base by means of an elevator from a horizontal position into a position between 5° and 90°;
- d) during the raising of the base, screwing the top drive to the pipe by a drive shaft of the top drive, securing the top drive and then moving the top drive one of with the pipe-handling apparatus and by means of a linear drive into an upper region of a roughneck, grasping a lower pipe connector of the pipe with a breaking and securing apparatus of the roughneck holding the string;
- e) screwing the pipe with one of the top drive and the roughneck to a drilling string within the well;
- and
- f) again moving the pipe-handling apparatus into the base and the holder for the lower pipe, connected to a drill bit, opening the pipe-handling apparatus and beginning a drilling operation, the top drive being lowered in a guide means of the base.
A method for sinking a well by means of a drilling machine having a base having a foot and a longitudinal axis, a top drive arranged one of on and in the base so as to be displaceable axially to the longitudinal axis of the base, and a pipe-handling apparatus integrated in the base so as to be movable perpendicularly to the longitudinal axis of the base and which grips a drilling pipe, the base being pivotably and rotatably mounted in a region of the foot such that the base is pivotal from a substantially vertical position toward a horizontal position and is rotatable about the longitudinal axis of the base in the substantially vertical position, the method comprising the steps of removing a pipe From a pipe rack, in which the drilling pipe is arranged vertically, by means of the pipe-handling apparatus, which is integrated into the drilling machine;
- screwing the pipe to the top drive by means of the pipe-handling apparatus;
- and bringing the pipe into a drilling position.
A drilling machine, comprising:
- a base having a foot and a longitudinal axis;
- a top drive arranged one of on and in the base so as to be displaceable axially to the longitudinal axis of the base;
- a pipe-handling apparatus arranged one of on and in the base so as to be movable perpendicularly to the longitudinal axis of the base and which grips a drilling pipe, the base being at least one of pivotably and rotatably mounted in a region of the foot;
- a steel structure;
- and a locking apparatus arranged at an upper end of the base and connected to the steel structure, the locking apparatus including a hollow cylinder, a flushing hose connected to the hollow and a valve arranged to ensure flushing feed.
A drilling machine, comprising:
- a base having a foot and a longitudinal axis;
- a top drive arranged one of on and in the base so as to be displaceable axially to the longitudinal axis of the base;
- a pipe-handling apparatus arranged one of on and in the base so as to be movable perpendicularly to the longitudinal axis of the base and which grips a drilling pipe, the base being at least one of pivotably and rotatably mounted in a region of the foot;
- and an elevator operatively arranged to raise the base from horizontal to vertical, the elevator including a winch.
A drilling machine, comprising:
- a base having a foot and a longitudinal axis;
- a top drive arranged one of on and in the base so as to be displaceable axially to the longitudinal axis of the base;
- a pipe-handling apparatus arranged on of one and in the base so as to be movable perpendicularly to the longitudinal axis of the base and which grips a drilling pipe, the base being at least one of pivotably and rotatably mounted in a region of the foot;
- and a power rough neck arranged below the pipe handling apparatus, the power rough neck including a holder and a breaking and securing apparatus, the rough neck being connected to the base so as to be displaceable perpendicularly to the axis of the base and raisable by the top drive via a coupling.
A method for sinking a well by means of a drilling machine having a base having a foot and a longitudinal axis, a top drive arranged one of on and in the base so as to be displaceable axially to the longitudinal axis of the base, and a pipe-handling apparatus arranged one of on and in the base so as to be movable perpendicularly to the longitudinal axis of the base and which grips a drilling pipe, the base being at least one of pivotably and rotatably mounted in a region of the foot, the method comprising the steps of:
- removing a pipe from a pipe rack, in which the drilling pipe is arranged vertically, by means of the pipe-handling apparatus, which is integrated into the drilling machine;
- screwing the pipe to the top drive by means of the pipe-handling apparatus;
- and bringing the pipe a drilling position, further including bringing at least two drilling machines into position around a well, sinking one drilling pipe in alternation while at least one of the drilling machine is prepared for drilling by receiving a further pipe.
