Abstract
The utility model relates to a waterproof conduit shoe with fast penetrability. The waterproof conduit shoe with the fast penetrability is characterized by comprising a conduit shoe body and a wedge-shaped structure which is integrally formed with the conduit shoe body, wherein the bottom of the wedge-shaped structure is arranged in a taper-angle mode, the angle of the taper angle is alpha, a plurality of conduit shoe teeth are arranged at intervals on the periphery of the wedge-shaped face of the lower end of the wedge-shaped structure, and a plurality of reinforcing ribs are further arranged at intervals from the upper middle portion of the conduit shoe body to the bottom end of the wedge-shaped structure along the peripheral axial direction of the conduit shoe body and the peripheral axial direction of the wedge-shaped structure. According to the waterproof conduit shoe with the fast penetrability, due to the facts that the conduit shoe body and the wedge-shaped structure which is integrally formed with the conduit shoe body are adopted and the bottom of the wedge-shaped structure is arranged in the taper-angle mode, after a soil plug is formed inside the conduit shoe, the conduit shoe serves as the wedge-shaped structure, the conduit shoe has good guiding performance during a piling process, and the penetrability of the conduit shoe can be effectively improved. The waterproof conduit shoe with the fast penetrability can be widely applied to the field of petroleum exploration and development and foundation construction of the building industry.
Description
Technical field
The utility model relates to a kind of offshore drilling equipment, particularly about a kind of be applied in the offshore oil exploration development process to be connected with riser pipe use penetrate riser pipe shoe soon.
Background technology
In the petroleum exploration and development process, require the riser pipe piling work in the short as far as possible time, conduit to be squeezed into the following projected depth of mud line at sea.Because different waters seafloor soil character varies, the soil layer Strength Changes is very big, has arrived darker high strength soil layer especially, and pile penetration is very little in riser pipe piling process, and the piling timeliness is very low.Therefore, how to improve the pipe shoe penetration capacity, increase the piling pile penetration, save the piling time, improve the marine guidance piling timeliness and become problem demanding prompt solution.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides a kind of riser pipe shoe that penetrates soon, and it can effectively improve the pipe shoe penetration capacity, increases the piling pile penetration, saves the piling time, improves the marine guidance piling timeliness.
For achieving the above object, the utility model is taked following technical scheme: a kind of riser pipe shoe that penetrates soon, it is characterized in that: it comprises pipe shoe main body and wedge structure integrated with it, and described wedge structure bottom is the cone angle setting, and the angle of described cone angle is α; The lozenges peripheral region is arranged at intervals with some pipe shoe teeth in described wedge structure lower end; To described wedge structure bottom, also be arranged at intervals with plurality of strengthening ribs from described pipe shoe main body middle and upper part along described pipe shoe main body and wedge structure peripheral, axial.
The angle [alpha] of described cone angle is less than 90 °.
Described wedge structure lower end lozenges peripheral region is arranged at intervals with 20～40 described pipe shoe teeth.
Be arranged at intervals with 10～20 described reinforcing ribs in described pipe shoe main body and wedge structure peripheral, axial.
The utility model is owing to take above technical scheme, it has the following advantages: 1, the utility model is owing to adopt pipe shoe main body and wedge structure integrated with it, and the wedge structure bottom is the cone angle setting, like this after forming the soil plug in the pipe shoe, the pipe shoe place is equivalent to a wedge structure, in the piling process, have good guidance quality, and can effectively improve the pipe shoe penetration capacity.2, the utility model is because employing is arranged at intervals with some pipe shoe teeth at wedge structure lower end lozenges peripheral region, go into the increase of the mud degree of depth along with riser pipe, it is more and more harder that the stratum can become, this wedge structure pipe shoe that has some pipe shoe teeth has splits native effect, the pipe shoe bottom soil body is squeezed to both sides open, to improve its pile penetration greatly easilier.3, owing to can run into the bigger stone or the obstructions such as hard objects of larger volume in the piling process, the wedge structure pipe shoe that the utility model adopts can have good trafficability characteristic under the situation of not damaging the riser pipe main body.The utility model can be widely used in various oil exploration and development fields and the building trade foundation construction.

Fig. 1 is an overall structure schematic diagram of the present utility model;
Fig. 2 is the front view of Fig. 1;
Fig. 3 is the lateral view of Fig. 1;
Fig. 4 is that of the present utility model penetrating soon split native schematic diagram in the riser pipe shoe penetration process.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
As Fig. 1～shown in Figure 3, the utility model comprises pipe shoe main body 1 and wedge structure integrated with it 2, wedge structure 2 bottoms are cone angle 3 and are provided with, the angle of this cone angle 3 is α, like this in the piling process, the wedge structure 2 by pipe shoe main body 1 bottom makes riser pipe shoe have good guidance quality and fast penetration capacity.Be arranged at intervals with some pipe shoe teeth 4 at wedge structure 2 lower end lozenges peripheral regions, can effectively improve the riser pipe shoe penetration capacity that penetrates soon of the present utility model by cone angle 3 and pipe shoe tooth 4.To wedge structure 2 bottoms, also be arranged at intervals with plurality of strengthening ribs 5 from pipe shoe main body 1 middle and upper part, 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 the foregoing description, the angle [alpha] of cone angle 3 is less than 90 °, and the concrete angle of α need be determined according to seafloor soil soil property intensity size, the stratum that intensity is big more, and cone angle 3 angle [alpha] are more little.
In the various embodiments described above, wedge structure 2 lower end lozenges peripheral regions are 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 utility model in use, as shown in Figure 4, by with pipe shoe main body 1 integrated wedge structure 2, make the utility model by the stratum time, have guidance quality and penetration capability preferably.Go into the increase of the mud degree of depth along with riser pipe, in riser pipe, slowly produce the soil plug, the soil that forms beyond the Great Wall shape profile and wedge structure 2 profile phase with, being lowered to along with riser pipe then, the soil plug that has wedge structure is equivalent to a high-intensity chock, play the effect on the stratum of riving, the ability that makes riser pipe shoe pierce through the stratum strengthens greatly.Can improve riser pipe piling efficient so greatly, shorten the riser pipe piling construction time, improve the development benefit of oil gas field.
The various embodiments described above only are used to illustrate the utility model; the connection of each parts and structure all can change to some extent; on the basis of technical solutions of the utility model; all improvement and equivalents of the connection and the structure of individual component being carried out according to the utility model principle all should not got rid of outside protection domain of the present utility model.
