Abstract
The utility model relates to a suction pile type ocean floor drilling novel basal disc, which comprises a file base, a guide cylinder and a case basal disc, and is characterized in that the pile base adopts a suction pile base, a suction pile and the case basal disc are connected by the guide cylinder to form an integrated structure which is leveled simultaneously in suction sinking process, and the guide cylinder and the center of the top of the suction pile are welded to form a whole body; the guide cylinder passes through the case basal disc and is welded into a whole body; and a pumping hole is arranged at the top of the suction pile and used for installing a pump for pumping water in the suction pile. The suction pile type ocean floor drilling novel basal disc has the advantages that the self-floating towage can be realized by relying on the buoyancy provided by air enclosed in the case basal disc and the suction pile, the water sinking can be realized by a small-size loop wheel machine, the leveling operation of the basal disc can be carried out at the same time of sinking the suction pile, and large-size devices or special devices, such as barges, floating cranes, pile hammers, levelers, grouters, and the like are unnecessary to be used during the marine installation process, thereby simplifying the marine installation procedures and achieving the aims of shortening the marine installation completion period and reducing the cost.
Description
Technical field
The utility model belongs to the innovation of ocean engineering field ocean floor drilling basal disc structural shape.
Background technology
In the marine petroleum development,, recoup capital outlay as early as possible, adopt usually in the pre-scheme of carrying out the preboring well on the basal disc of seabed of installing in order to shorten the cycle of offshore oil field development engineering.After pre-drilling well was finished, interim abandoned well carried out the installation of jacket and upper module then, carries out tieback and completion operation with the service machine on the jacket platform at last.Because the engineering design of drilling operation and platform facility is carried out simultaneously with construction, this scheme has shortened the time-to-market before going into operation greatly.The ocean floor drilling basal disc is the structure facility of pre-drilling operation, and traditional ocean floor drilling basal disc adopts driven pile to be fixed in the seabed.Common way is earlier the ocean floor drilling basal disc to be lifted the seabed, drives piles along the basal disc sleeve then; After finishing, piling adjusts the levelness of ocean floor drilling basal disc, then grouted solid between stake and basal disc sleeve by special-purpose leveller.The part of driven pile more than the basal disc sleeve be as the direction peg that jacket docks with template, and the level from jacket of bearing is to impact.Tradition ocean floor drilling basal disc installation process, piling work, leveling operation and grouting operation are arranged, need construction equipment to be useful on and load barge, the crane barge that is used to lift ocean floor drilling basal disc and stake that transports ocean floor drilling basal disc and stake, the special-purpose leveller that is used for the leveling of ocean floor drilling basal disc, and drive hammer, grouting equipment etc., not only the construction period longer, and executive cost is high.
Summary of the invention
In order to shorten the marine installation period of ocean floor drilling basal disc, and the reduction expense, the utility model provides a kind of suction pile formula ocean floor drilling basal disc.This basal disc can be realized self-floating towing by the body structure of self; Just can realize transferring in the water by small-sized loop wheel machine, and can in suction pile negative pressure sinking process, finish the basal disc leveling, need not piling, leveling, grouting operation, thereby simplified marine erection procedure, reach the purpose that shortens marine installation period, reduces erected cost.
The technical scheme that its technical matters that solves the utility model adopts is: the ocean floor drilling basal disc is made up of pile foundation, guide cylinder and casing basal disc, tool is characterised in that pile foundation adopts suction pile, and suction pile and casing basal disc are connected to the integral structure of being convenient to leveling simultaneously in the suction sinking by guide cylinder.The center of top of guide cylinder and suction pile is welded as a whole; Guide cylinder passes the casing basal disc and is welded as a whole; The suction pile top is provided with pumping hole, is used for the pump that extracts water in the suction pile is installed, as diving pump or air-powered pump etc.After suction pile formula ocean floor drilling basal disc lifting entry, the confining gas in the suction pile provides the floating certainly buoyancy of a part, and not enough part is provided by casing, so on the ocean floor drilling basal disc can bubble through the water column certainly, is dragged to the installation site by tugboat; Can realize setting upright down in the ocean floor drilling basal disc water by small-sized loop wheel machine (hanging) then and put into mud as the side of a ship on the tugboat; The ocean floor drilling basal disc by extracting the water in the suction pile, makes in the suction pile injection ocean bottom soil after relying on deadweight to make the suction pile initial penetration into mud reach the native air-proof condition of stake; And, adjust pairing suction pile and go into the mud degree of depth, thereby the levelness of adjustment basal disc by controlling four suction pile top diving capacity of pump respectively.
The beneficial effects of the utility model are, marine installation process does not need to use Large-Scale Equipments such as barge, crane barge, drive hammer, do not need to use special-purpose leveller, grouting equipment yet, only need a tugboat to get final product, therefore can significantly shorten marine installation period, reduction expense.

The specific embodiment
The structure of suction pile formula ocean floor drilling basal disc is seen Fig. 1 and Fig. 2, is made up of four suction piles 1, four guide cylinders 2 and casing basal disc 3, and guide cylinder 2 is positioned at the center of top of suction pile 1, and casing basal disc 3 passes guide cylinder 2 and is attached thereto; The suction pile top is provided with pumping hole 4, and diving pump 5 or air-powered pump are installed in its top.
Suction pile formula ocean floor drilling basal disc self-floating towing state is seen Fig. 3 a and Fig. 3 b, this moment, suction pile 1 interior confining gas provided the floating certainly buoyancy of a part, not enough buoyancy is provided by casing basal disc 3, so suction pile formula ocean floor drilling basal disc can bubble through the water column on 7 certainly, is dragged to the installation site by tugboat 6.
By the side of a ship on the tugboat hang with set upright down in the suction pile formula ocean floor drilling basal disc water put into mud after.After suction pile formula ocean floor drilling basal disc relies on deadweight to make the suction pile initial penetration into mud reach the native air-proof condition of stake, by extracting the water in the suction pile, make in the suction pile injection ocean bottom soil 8, in injection soil 8 processes, by controlling the discharge capacity of four suction pile 1 top diving pumps 5 respectively, adjust pairing suction pile 1 and go into the mud degree of depth, thereby the levelness of adjustment basal disc is seen Fig. 4.
