Abstract
A kind of boats and ships drilling platform, comprise hull, spar deck, drill outfit, spud leg and elevator, described spar deck is positioned on the deck of hull, described spar deck end face is provided with drill outfit, described spar deck bottom surface is provided with the spud leg that can shrink, and is provided with for controlling the elevator of spar deck lifting on described spud leg; During work, hull is stopped to new well location, spud leg is transferred and is inserted seabed, and elevator is controlled spar deck along spud leg lifting, and hull pulls the plug, and spar deck is raised to the trouble free service height that leaves sea, and drill outfit is started working; After drill outfit work completes, elevator is controlled spar deck along spud leg lifting, and spud leg reclaims, and completes the work of one-period; The utility model can arrange spud leg and elevator on the spar deck of hull, has that Occupation coefficient is high, production efficiency is high, good stability, endurance is strong, operating depth is large, mobile feature flexibly.
Description
Technical field
The utility model relates to offshore oil exploitation technical field, particularly a kind of boats and ships drilling platform.
Background technology
Creep into platform and be mainly divided into jack-up drilling unit and semi-submersible drilling unit.
Jack-up drilling unit is comprised of platform, spud leg and lifting mechanism.During work, spud leg is transferred and is inserted seabed, and platform can be along spud leg lifting, and platform is raised to the trouble free service height that leaves sea, and completion rear platform drops to sea, extracts spud leg and all mentions, and whole platform floats on sea, by tugboat, is dragged to new well location.Jack-up drilling unit working stability is good and production efficiency is high, but extremely bothers at moving process.Semi-submersible drilling unit top is spar deck, and bottom is two lower hulls, with support post, connects.During work, lower hull pulls the plug, and deck is in water safety height.It is little that semi-submersible drilling unit has water plane area, and wave effect is little, and good stability, endurance is strong, operating depth is large, mobile advantage flexibly.But it is large that shortcoming is investment, and standing charges are high, need have the utensil under water of a set of complexity, and availability are lower than jack-up drilling unit.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of boats and ships drilling platform, can spud leg and elevator be set on the spar deck of hull, have that Occupation coefficient is high, production efficiency is high, good stability, endurance is strong, operating depth is large, mobile feature flexibly.
In order to achieve the above object, the technical scheme that the utility model is taked is:
A kind of boats and ships drilling platform, comprise hull 1, spar deck 2, drill outfit 3, spud leg 4 and elevator 5, described spar deck 2 is positioned on the deck of hull 1, described spar deck 2 end faces are provided with drill outfit 3, described spar deck 2 bottom surfaces are provided with the spud leg 4 that can shrink, and are provided with for controlling the elevator 5 of spar deck 2 liftings on described spud leg 4.
Principle of work of the present utility model is:
During work, hull 1 is stopped to new well location, spud leg 4 is transferred and is inserted seabed, and elevator 5 is controlled spar deck 2 along spud leg 4 liftings, and hull 1 pulls the plug, and spar deck 2 is raised to the trouble free service height that leaves sea, and drill outfit 3 is started working.After drill outfit 3 has been worked, elevator 5 is controlled spar deck 2 along spud leg 4 liftings, and spud leg 4 reclaims, and completes the work of one-period.
The beneficial effects of the utility model are:
The utility model can arrange spud leg and elevator on the spar deck of hull, has that Occupation coefficient is high, production efficiency is high, good stability, endurance is strong, operating depth is large, mobile feature flexibly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Referring to accompanying drawing, the utility model is a kind of boats and ships drilling platform, comprise hull 1, spar deck 2, drill outfit 3, spud leg 4 and elevator 5, described spar deck 2 is positioned on the deck of hull 1, described spar deck 2 end faces are provided with drill outfit 3, described spar deck 2 bottom surfaces are provided with the spud leg 4 that can shrink, and are provided with for controlling the elevator 5 of spar deck 2 liftings on described spud leg 4.
During work, hull 1 is stopped to new well location, spud leg 4 is transferred and is inserted seabed, and elevator 5 is controlled spar deck 2 along spud leg 4 liftings, and hull 1 pulls the plug, and spar deck 2 is raised to the trouble free service height that leaves sea, and drill outfit 3 is started working.After drill outfit 3 has been worked, elevator 5 is controlled spar deck 2 along spud leg 4 liftings, and spud leg 4 reclaims, and completes the work of one-period.
