Description
Technical Field
The invention relates to the field of transfer of offshore oil platform drilling machine systems, in particular to a rapid shifting operation method of an offshore oil platform module drilling machine system.
Background
Offshore oil platforms typically employ modular drilling rigs for platform drilling completion operations. The offshore platform is generally provided with a plurality of well slots, when the modular drilling rig works in the next well slot before finishing the operation in a certain well slot position, the lifting vertical pipe needs to be lifted in the conventional operation, the connecting bolt between the lifting vertical pipe and the blowout preventer is removed, the lifting vertical pipe is shifted to a new well slot position, then the connection is recovered, and the lifting vertical pipe is placed down to meet the operation conditions. The above process often requires 1 to 2 days of operation time, resulting in a large increase in the cost of drilling and completing the well.
Disclosure of Invention
The technical problem to be solved by the invention is how to provide a quick displacement operation method for an offshore oil platform module drilling machine system.
In order to solve the technical problems, the invention provides a rapid displacement operation method of an offshore oil platform module drilling machine system, which is completed by the following steps:
s1, positioning a modular drilling machine system at a well position to be drilled;
s2, a module drilling machine carries out and completes the well drilling operation of the well position;
s3, disconnecting a lifting riser in the module drilling machine system and connecting the lifting riser with the Christmas tree;
s4, opening a top deck structure beam in the direction to be shifted;
s5, the modular drilling machine system together with the lifting vertical pipe and the blowout preventer is shifted to the next well position to be drilled;
and S6, recovering the structural beam of the completed well position and the next well position to be drilled, namely completing the rapid displacement of the modular drilling machine system.
Further, the connection between the riser and the blowout preventer need not be removed when displaced.
Furthermore, the two ends of the top deck structural beam are connected through bolts, so that the disassembly and recovery time is short and the fire operation is not needed.
Furthermore, when the modular drilling rig system carries out well position displacement operation, the modular drilling rig system and the lifting vertical pipe are displaced together with the blowout preventer, so that operations of dismounting the lifting vertical pipe, recovering after displacement and the like are avoided.
The invention has the technical effects that: according to the invention, the module drilling machine system together with the lifting vertical pipe and the blowout preventer are moved to the peripheral well position by disassembling the top layer movable deck beam, so that the operations of disassembling and installing the connection between the lifting vertical pipe and the blowout preventer are avoided, and the operation amount and cost of drilling and completion are saved.
Drawings
FIG. 1 is a schematic diagram of the displacement of a drilling system in the method for the rapid displacement operation of the modular offshore oil platform drilling rig system according to the embodiment of the invention.
Detailed Description
The present invention is further described with reference to the following drawings and specific examples so that those skilled in the art can better understand the present invention and can practice the present invention, but the examples are not intended to limit the present invention.
The embodiment of the invention provides a rapid shifting operation method of an offshore oil platform module drilling machine system, which is combined with the attached drawing 1 and is completed through the following steps:
s1, positioning a modular drilling machine system at a well position to be drilled;
s2, a module drilling machine carries out and completes the well drilling operation of the well position;
s3, disconnecting the rising riser in the modular drilling rig system and connecting the rising riser with the Christmas tree;
s4, opening a top deck structure beam in the quasi-displacement direction;
s5, the module drilling machine system together with the lifting vertical pipe and the blowout preventer are shifted to the next well position to be drilled;
and S6, recovering the structural beam of the completed well position and the next well position to be drilled, namely completing the rapid displacement of the modular drilling machine system.
In this embodiment, the connection between the riser and the blowout preventer need not be removed when displaced.
In this embodiment, bolted connection is adopted at top layer deck structure roof beam both ends, unpacks apart and recovery time is short and need not the operation of starting a fire.
In the embodiment, when the modular drilling rig system performs well position displacement operation, the modular drilling rig system and the lifting vertical pipe are displaced together with the blowout preventer, so that operations such as dismantling of the lifting vertical pipe and recovery after displacement are avoided.
As shown in fig. 1, the fast shift method provided by the present invention is completed by the following steps: (1) initially positioning the modular drilling system at a # 1 well site; (2) The modular drilling machine system carries out and completes the drilling and completion operation of the 1# well position; (3) disconnecting the riser with the Christmas tree; (4) opening the structural beam between the 1# well position and the 2# well position; (5) The modular drilling system is connected with a lifting vertical pipe and a blowout preventer to be simultaneously displaced to a No. 2 well position; (6) recovering the structural beam between the 1# well position and the 2# well position; (7) The modular drilling system completes the shift and begins a new drilling and completion operation.
The above-mentioned embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto. The equivalent substitution or change made by the technical personnel in the technical field on the basis of the invention is all within the protection scope of the invention. The protection scope of the invention is subject to the claims.
