Description
Technical field
The present invention relates to a kind of devices for being completed at the same time sub-sea drilled wells cutting and salvaging with capping operation, belong to offshore drilling's envelope
Well technical field.
Background technique
As offshore oil exploration and exploitation is to deep-water developments, the mankind increase marine environmental protection dynamics, it is desirable that discarded
Offshore oil facility carries out abandoned well operation, and abandoned well operation is firstly the need of by the casing of wellhead installation and disused well middle and upper part certain depth
Come from casing program design with conduit, with collided when preventing passing ships by well head seabed waste petroleum facility and casing and
Conduit causes the accident.Then cement slurry is injected in disused well by grouting equipment again and closes disused well, to prevent long-time
The oil and gas of accumulation is gushed out well head and is polluted to ocean.
The capping operation on existing ground is usually to be carried out in two steps, and the first step is by cutting and marine salvage equipment by oil well
In casing cutting, salvaged out of oil well together with the conduit outside casing come.Second step is infused cement slurry using grouting equipment
Enter in disused well, completes capping operation.
The cutting and marine salvage equipment that existing ground uses mostly use the cutter or slips of hydraulic system driving equipment.Due to liquid
It presses drive system to require hydrophthalmia diameter too big, certain pressure could be formed in drilling rod by section difference in drilling rod in this way
Power is poor, to ensure to cut the normal work with marine salvage equipment.Due to the hydrophthalmia very little in existing equipment drilling rod.Hydrophthalmia is exactly when sealing
The channel of cement slurry.When passing through small hydrophthalmia, not reaching predetermined depth cement slurry will also solidify cement slurry, lead to nothing when shut-in well
Method is further continued for injection cement slurry, influences quality of shunting in a well.It therefore can only be using two steps shut-in well mode using existing ground shut-in well equipment.
Two steps shut-in well mode is not suitable for seabed capping operation.Casing and conduit are salvaged from disused well when having cut casing
When out, the silt in seabed can quickly be buried disused well well head, when needing to carry out capping operation again, be difficult to find original well
Mouthful.If drilling platforms needs back port to hide when encountering typhoon or billow, back after can not find original well head at all, can only
Selection is abandoned shunting in a well.The oil and gas of long-time accumulation in this way, which is possible to gush out well head, pollutes ocean.
There is also drilling platforms to float across the sea with land shut-in well for ocean shut-in well, is influenced by wave, drilling well is flat
Platform can be with wave dipping and heaving, while driving drill string also while dipping and heaving, and the dipping and heaving of drill string will affect cutting for cutter
Cut position.Therefore the prior art is unable to satisfy seabed capping operation demand.
Summary of the invention
It is completed at the same time sub-sea drilled wells cutting the purpose of the present invention is to provide a kind of and salvages and the device of capping operation, it can one
Be drilled under secondary and cut off casing, and casing and conduit are come from casing program design, it is upper mention drilling rod when, while being injected into well
Cement slurry completes capping operation；Seabed capping operation requirement can not only be met, be also greatly improved and improve seabed capping operation effect

Embodiment
This example is completed at the same time the device of sub-sea drilled wells cutting salvaging and capping operation, as shown in Figure 1.The device of this example is by upper
It can be divided under and salvage section 10, flexible compensation section 20, righting section 30 and cut length 40.The above each section of head and the tail are connected through a screw thread
For entirety.
The fishing that section 10 is responsible for shut-in procedures is salvaged, after salvaging 10 lower end sleeve pipe of section, positioning ring 18 is located at
Cannula tip plays the role of positioning, and positioning ring 18 can be adjusted according to 1 inner card cage position of casing.By the slips 11 for salvaging section 10
It is caught in the card slot of casing 1 and blocks casing 1.
Cut length 40 is responsible for before shut-in well cutting off casing 1.The cutter 21 of cut length 40 is suppressed by cement slurry, makes cutter
21 open, and rotary drill column cutter 21 can cut casing 1.Steel ball is put into after the completion of cutting, cut length 40 is additionally formed
Grout channels enable cement slurry to be additionally formed grout channels between piston 45 and outer tube 42 by carrying out shut-in well work
Industry.Cutter 21 is exercised on piston 45 simultaneously to be contracted in the cutter groove of outer tube 42.
The variation that flexible compensation section 20 passes through length, it is ensured that effect be during Casing-Cutting 1, it is ensured that cut
Knife 21 will not be such that cutter 21 is cut always in same position, keep cutting process unaffected with wave dipping and heaving.
Righting section 30 is used for righting drill string, makes cutter 21 will not be eccentric in cutting process.
The course of work and principle of the invention is described as follows:
After the device of the invention tripping in oil well, by salvaging the slips 11 in section 10 for 1 clamping of casing.Then it is beaten by cement slurry
Pressure expands outwardly the cutter 41 in cut length 40, and rotary drill column can cut casing 1.Flexible compensation in cutting process
Section 20 can automotive resistance drill string fluctuating, so that cutter is remained at same position.Righting section 30 can righting drill string make cutter 41
It will not be eccentric when cutting.After casing is cut off, steel ball 3 is put into the grout channels of drill string, steel ball 3 falls into cut length 40
Ball seat 47 aperture after, close cut state when 48 channel of metering hole, during 45 downlink of piston open piston 45 with
Another channel cement slurry between outer tube 42, cement slurry are no longer pass through 48 channel of metering hole, and cutter 41 automatically retracts outer tube 42
Cutter groove in.Due to the flow area of metering hole 48 when the grout channels flow area newly opened is far longer than cutting, can make
Cement slurry passes through.Cut-off casing 1 is mentioned upwards on one side at this time, and cement slurry is injected in grout channels on one side can complete to seal
Well operations.
By adopting the above-described technical solution, the pure machine of the cutter course of work of the invention using card key and the cooperation of J-shaped slot
Tool driving method can to greatly expand the through-current capacity of grout channels instead of the hydraulic driving mode of the prior art
Slow down setting time of the cement slurry in channel.To which once lower bore sea can be completed at the same time with the cooperation of submarine fishing well-sealing device
The salvaging of the casing-pipe cutting of base oil well, casing and conduit and the capping operation of oil well.Compared with prior art, it has solved
Seabed silt buries wellbore after brill, wellbore before being difficult to find when lower drilling row capping operation again or can not find wellbore
Technical problem.The configuration of the present invention is simple, it is economical and practical, the artificial and energy consumption to make a trip repeatedly can be reduced.Also avoid because
It can not find the direct abandoned well of wellbore, cause the oil and gas accumulated for a long time in well to return out well head and ocean is polluted, prevented also from ship
The waste petroleum facility that seabed is collided when only passing through causes the accident.The present invention has structure simple, and low manufacture cost, operation can
By the characteristics of.
