Abstract
The present invention relates to one and penetrate riser pipe shoe soon, it is characterized in that: it comprises pipe shoe main body and wedge structure integrated with it, arrange in cone angle bottom described wedge structure, the angle of described cone angle is α; In described wedge structure lower end, lozenges peripheral region is arranged at intervals with some pipe shoe teeth; From described pipe shoe main body middle and upper part to described wedge structure bottom, be also arranged at intervals with some reinforcing ribs along described pipe shoe main body and wedge structure peripheral, axial.The present invention is owing to adopting pipe shoe main body and wedge structure integrated with it, and arrange in cone angle bottom wedge structure, like this after forming soil plug in pipe shoe, pipe shoe place is equivalent to a wedge structure, in piling process, there is good guidance quality, and can effectively improve pipe shoe penetration capacity.The present invention can be widely used in various oil exploration and development fields and building trade foundation construction.
Description
Technical field
The present invention relates to a kind of offshore drilling equipment, particularly about a kind of be applied in offshore oil exploration development process be connected with riser pipe use penetrate riser pipe shoe soon.
Background technology
At sea in petroleum exploration and development process, require that riser piling operating squeezes into the following projected depth of mud line conduit within the time short as far as possible.Because different waters seafloor soil character varies, soil layer Strength Changes is very large, and arrived darker high strength soil layer especially, in riser pipe piling process, pile penetration is very little, and piling timeliness is very low.Therefore, how to improve pipe shoe penetration capacity, increase piling pile penetration, save the piling time, improve marine guidance piling timeliness and become problem demanding prompt solution.
Summary of the invention
For the problems referred to above, the object of this invention is to provide one and penetrate riser pipe shoe soon, it can effectively improve pipe shoe penetration capacity, increases piling pile penetration, saves the piling time, improve marine guidance piling timeliness.
For achieving the above object, the present invention takes following technical scheme: one penetrates riser pipe shoe soon, it is characterized in that: it comprises pipe shoe main body and wedge structure integrated with it, arrange in cone angle bottom described wedge structure, the angle of described cone angle is α; In described wedge structure lower end, lozenges peripheral region is arranged at intervals with some pipe shoe teeth; From described pipe shoe main body middle and upper part to described wedge structure bottom, be also arranged at intervals with some reinforcing ribs along described pipe shoe main body and wedge structure peripheral, axial.
The angle [alpha] of described cone angle is less than 90 °.
The angle [alpha] of described cone angle is determined according to seafloor soil soil strength size, the stratum that intensity is larger, and described angle of taper α is less.
Described wedge structure lower end lozenges peripheral region is arranged at intervals with 20 ~ 40 described pipe shoe teeth.
10 ~ 20 described reinforcing ribs are arranged at intervals with in described pipe shoe main body and wedge structure peripheral, axial.
The present invention is owing to taking above technical scheme, it has the following advantages: 1, the present invention is owing to adopting pipe shoe main body and wedge structure integrated with it, and arrange in cone angle bottom wedge structure, like this after forming soil plug in pipe shoe, pipe shoe place is equivalent to a wedge structure, in piling process, there is good guidance quality, and can effectively improve pipe shoe penetration capacity.2, the present invention is arranged at intervals with some pipe shoe teeth owing to adopting at wedge structure lower end lozenges peripheral region, along with the increase of riser pipe driving depth, stratum can become more and more harder, this wedge structure pipe shoe with some pipe shoe teeth has splits native effect, more easily make the pipe shoe bottom soil body squeeze to both sides, greatly improve its pile penetration.3, owing to can run into the obstructions such as the hard objects of larger stone or larger volume in piling process, the wedge structure pipe shoe that the present invention adopts can have the good property passed through when not damaging riser pipe main body.The present invention can be widely used in various oil exploration and development fields and building trade foundation construction.

Fig. 4 is that of the present invention penetrating soon in riser pipe shoe penetration process splits native schematic diagram.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail.
As shown in FIG. 1 to 3, the present invention includes pipe shoe main body 1 and wedge structure integrated with it 2, arrange in cone angle 3 bottom wedge structure 2, the angle of this cone angle 3 is α, like this in piling process, riser pipe shoe is made to have good guidance quality and fast penetration capacity by the wedge structure 2 bottom pipe shoe main body 1.In wedge structure 2 lower end, lozenges peripheral region is arranged at intervals with some pipe shoe teeth 4, effectively can be improved of the present inventionly penetrate riser pipe shoe penetration capacity soon by cone angle 3 and pipe shoe tooth 4.From pipe shoe main body 1 middle and upper part to wedge structure 2 bottom, be also arranged at intervals with some reinforcing ribs 5, to improve the bulk strength of pipe shoe main body 1 and wedge structure 2 along pipe shoe main body 1 and wedge structure 2 peripheral, axial.
In above-described embodiment, the angle [alpha] of cone angle 3 is less than 90 °, and the concrete angle of α needs to determine according to seafloor soil soil strength size, and the stratum that intensity is larger, cone angle 3 angle [alpha] is less.
In the various embodiments described above, wedge structure 2 lower end lozenges peripheral region is arranged at intervals with 20 ~ 40 pipe shoe teeth 4.
In the various embodiments described above, be arranged at intervals with 10 ~ 20 reinforcing ribs 5 in pipe shoe main body 1 and wedge structure 2 peripheral, axial.
The present invention in use, as shown in Figure 4, by wedge structure 2 integrated with pipe shoe main body 1, makes the present invention by having good guidance quality and penetration capability during stratum.Along with the increase of riser pipe driving depth, soil plug is slowly produced in riser pipe, the soil plug appearance profile formed is identical with the profile of wedge structure 2, then enter along with under riser pipe, soil plug with wedge structure is equivalent to the chock of a high strength, play the effect on a stratum of riving, the ability making riser pipe shoe pierce through stratum strengthens greatly.Greatly can improve riser pipe piling efficiency like this, shorten the riser pipe piling construction time, improve the development benefit of oil gas field.
The various embodiments described above are only for illustration of the present invention; the connection of each parts and structure all can change to some extent; on the basis of technical solution of the present invention; all improvement of carrying out the connection of individual part and structure according to the principle of the invention and equivalents, all should not get rid of outside protection scope of the present invention.
