Description of the drawings
Fig. 1 is the structure diagram of marine drilling platform described in the utility model.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to explanation
Book word can be implemented according to this.
It should be appreciated that such as " having ", "comprising" and " comprising " term used herein are not precluded from one or more
The presence or addition of a other elements or its combination.
As shown in Figure 1, the utility model provides a kind of marine drilling platform, including：Babinet 1 is square setting, described
First through hole 2 is offered on four sides of babinet 1；Platform 3 is more than the square setting of 1 upper surface area of babinet for area,
And the platform 3 and the longitudinally coaxial top for being arranged at the babinet 1 of the babinet 1, the corner of the platform 3 offers drilling well
Hole 4；The platform 3 is offering the second through hole 11 with the 2 corresponding position of first through hole；Telescopic mast 5 is arranged to 4,
4 telescopic masts 5 are arranged at four sides of the babinet 1 between the babinet 1 and platform 3 in telescopic manner respectively
On；Pillar 6, is arranged to 4, and the pillar 6 be arranged in described the in a manner of it can move up and down in the first through hole 2
In one through hole 2；Derrick 7 is arranged on the top of the well bore 4；Driving mechanism, including controller 8 and hydraulic pump 9, institute
It states hydraulic pump 9 and is controlled by the controller 8, the hydraulic pump 9 is connected to the telescopic mast 5 and pillar 6.
In said program, the specific method used of the marine drilling platform is：The offshore drilling is put down first
Platform is transported to corresponding drilling sites, and hydraulic pump is controlled by controller so that hydraulic pump drive pillar decline, and make pillar down toward
Then mud face more than 50cm or so fixes the position of rig floor platform after exact position is reached by pillar, then pillar is in liquid
Slowly babinet is jacked to predetermined absolute altitude under the driving of press pump, so by adjusting telescopic mast height to the levelness of platform into
Row fine tuning, is then fixed, and subsequently can then be needed to carry out drilling operation according to engineering construction.And at the end of construction, pass through first
Hydraulic pump slowly transfers babinet to the water surface, then proceedes to press babinet toward below water level line, to provide sufficiently large floating
Power extracts pillar below sea bed face, and then can carry out the construction in next place.By by babinet jacking to the water surface with
On so that it is farther apart from sea on the platform on babinet, operating personnel carry out operation when as land it is the same, ensure that personnel
And equipment safety, work efficiency is also improved, more important is for main platform body from the influence of current, wave, drilling tool will not
Disturbance is generated to the soil layer of bottom hole, has ensured the quality for taking soil sample, has ensured that in-situ test such as vane shear test, mark are passed through
The performance data accuracy of experiment etc. can also carry out the in-situ test such as static sounding that can not be carried out on ship cultivation drilling platform
Experiment etc..Derrick is respectively provided with by the corner in platform so that platform can be carried out at the same time four drilling well work, improve work
Efficiency, in addition also can be when a derrick damages, and derrick in addition can work on, and so as to avoid construction delay, improve
The utilization ratio of the marine drilling platform.
In one preferred embodiment, it is provided with what the pillar 6 and babinet 1 can be locked between the pillar 6 and babinet 1
Connection lock element 10.
In said program, by setting connection lock element between pillar and babinet so that pillar is dropping to stable depth,
And by after babinet jacking to predetermined altitude, babinet is fixed on pillar by connection lock element, so that babinet is across the sea
It is more firm, easily facilitate the progress of operation on platform.
In one preferred embodiment, the upper surface of the platform 3 is equipped with anti-skidding bed course.
In said program, by setting anti-skidding bed course on platform so that platform surface can be effectively anti-skidding, Jin Erfang
Just the work of staff avoids, because wet from sea water etc. cause to skid, the normal work of staff being influenced, so as to reduce
Work efficiency.
In one preferred embodiment, graduation mark is provided on the pillar 6.
In said program, because the soil property of seabed each several part is different so that the length of embedment of each pillar is different, receives
On pull out resistance and be also not quite similar, so pillar extracts operation certain processing arrangement is needed just to can guarantee that platform is smoothly stable extensive
Floating state is arrived again, and the pillar that otherwise will be had is extracted, and some pillars cannot extract or cause pillar to extract mud face
During flat surface over-tilting situation.And in order to ensure that platform is smoothly smoothly restored to floating state, usually according to
It according to the depth order below pillar insertion sea bed, is lifted successively from depth to shallow, but lifts dynamics difference and be not to be exceeded 30 centimetres, because
And by setting graduation mark on pillar, staff can be facilitated to understand the length of embedment of each pillar, while be also convenient for work
Control of the personnel to each pillar lifting dynamics.
In one preferred embodiment, the bottom of the pillar 6 is arranged to tip.
In said program, by the way that the bottom of pillar is arranged to tip so that pillar is more easy to stretch into the soil in seabed,
So as to improve the speed for platform stable of knowing clearly, be conducive to improve work efficiency.
In one preferred embodiment, one end of the telescopic mast 5 is connected to the center on four sides of the babinet 1, described flexible
The other end of column 5 vertically upward, and is fixedly connected with the bottom surface of the platform 3.
In said program, by the center with four sides of babinet being set to be attached telescopic mast so that 4 telescopic masts
It is symmetrical thus more steady for the support of the platform above babinet in tank surface, while because telescopic mast is arranged symmetrically,
Also it is more easy to the levelness of adjustment platform.
In one preferred embodiment, the size of the upper surface of the babinet 1 removes the size phase of well bore 4 with the platform 3
Cooperation.
In said program, it is engaged by limiting the size of upper surface of babinet with the size of platform removing well bore,
So that babinet will not be touched by being arranged at the work of the derrick of platform corner, hereby it is ensured that being smoothed out of probing work.
Although the embodiment of the utility model is disclosed as above, it is not restricted in specification and embodiment
Listed utilization, it can be applied to the field of various suitable the utility model completely, for those skilled in the art,
Other modification is easily achieved, therefore without departing from the general concept defined in the claims and the equivalent scope, this reality
Specific details is not limited to new and shown here as the legend with description.
