Abstract
The invention relates to a waterproof pipe shoe V-shaped tooth device which is characterized by comprising a rectangular mounting seat and a V-shaped tooth integrated with the mounting seat. A horizontal end face of the mounting seat is welded on the bottom periphery of a waterproof pipe shoe. The V-shaped tooth comprises two end faces and two lateral faces. The two end faces and the two lateral faces are integrated. The two end faces are of an equilateral triangle structure. The two lateral faces are rectangular. The mounting seat and the V-shaped tooth are made of high-hardness alloy steel, so that the pipe shoe can penetrate into hard stratum more conveniently, earth on two sides can be pushed away better, further penetration of a waterproof pipe is facilitated, and better passing ability is achieved while the pipe shoe is not damaged. The V-shaped tooth device is widely applicable to the field of petroleum exploration and development.
Description
Technical field
The present invention relates to a kind of offshore drilling equipment, particularly about the riser pipe shoe V-arrangement tooth apparatus be arranged in a kind of petroleum exploration and development process at sea on the pipe shoe that is connected with riser pipe.
Background technology
At sea in petroleum exploration and development process, the tooth Main Function of existing riser pipe shoe thrusts the soil body.As shown in Figure 1, existing pipe shoe tooth apparatus comprises mount pad 1 and conical tooth 2 integrated with mount pad 1, conical tooth 2 by four between two symmetrically arranged isosceles triangle form.Such tooth apparatus can play the effect penetrating hard formation, but effectively can not arrange the soil body, enters under being unfavorable for riser pipe.Therefore, existing pipe shoe tooth can not arrange the soil body effectively, the instructions for use entered under being unfavorable for riser pipe.The shortcoming of above-described existing riser pipe shoe tooth is badly in need of improving.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of riser pipe shoe V-arrangement tooth apparatus, it can make riser pipe under enter in process and not only can effectively make riser pipe shoe enter hard formation, and the soil body of discharge pipe sole end both sides can be helped, enter hard formation under making pipe shoe more convenient.
For achieving the above object, the present invention takes following technical scheme: a kind of riser pipe shoe V-arrangement tooth apparatus, it is characterized in that: it comprises mount pad and V-arrangement tooth integrated with described mount pad, the rectangular structure of described mount pad, its horizontal end face is welded on circumference bottom riser pipe shoe; Described V-arrangement tooth is made up of integrated two end faces and two sides, and described two end faces all adopt equilateral triangle structure, and described two sides all adopt rectangle structure.
The length b of described mount pad is 40mm, and width a is 18mm, and height H 1 is 8mm; The whole height H2 of described V-arrangement tooth and described mount pad is 30mm.
Described mount pad and V-arrangement tooth adopt 20Cr alloy steel to make.
Bottom described riser pipe shoe, circumference is arranged at intervals with riser pipe shoe V-arrangement tooth apparatus described in several, and between adjacent two described riser pipe shoe V-arrangement tooth apparatus, gap is 8mm.
The present invention is owing to taking above technical scheme, it has the following advantages: 1, the present invention is formed by mount pad with the integrated V-arrangement tooth of mount pad owing to adopting, mount pad and V-arrangement tooth adopt high hardness alloy steel to make, and its higher hardness can help pipe shoe to enter comparatively hard formation.2, the present invention is made up of integrated two end faces and two sides due to V-arrangement tooth, two end faces all adopt equilateral triangle structure, two sides all adopt rectangle structure, like this after pipe shoe enters stratum, soil at both sides can be arranged preferably, be beneficial to riser pipe further under enter, enter hard formation under making pipe shoe more convenient.3, the present invention is owing to adopting several V-arrangement teeth of circumference welding bottom pipe shoe, has in the earth formation preferably by property when it can be made not damage pipe shoe.The present invention can be widely used in various oil exploration and development fields.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing taper tooth;
Fig. 2 is that the present invention is arranged on riser pipe shoe bottom schematic view;
Fig. 3 is overall structure schematic diagram of the present invention, i.e. A place enlarged diagram in Fig. 2.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail.
As shown in Figure 2 and Figure 3, the present invention includes mount pad 3 and V-arrangement tooth 4 integrated with mount pad 3, the rectangular structure of mount pad 3, its horizontal end face is welded on circumference bottom riser pipe shoe 5.V-arrangement tooth 4 is made up of integrated two end faces 6 and two sides 7, and two end faces 6 all adopt equilateral triangle structure, and two sides 7 all adopt rectangle structure.
In above-described embodiment, the length b of mount pad 3 is 40mm, and width a is 18mm, and height H 1 is 8mm; V-arrangement tooth 4 is 30mm with the whole height H2 of mount pad 3.
In the various embodiments described above, mount pad 3 and V-arrangement tooth 4 adopt high hardness alloy steel to make, such as 20Cr alloy steel.Its higher hardness can help pipe shoe to enter comparatively hard formation.
In the various embodiments described above, as shown in Figure 2, bottom riser pipe shoe, circumference can be arranged at intervals with several riser pipe shoe V-arrangement tooth apparatus of the present invention, and between two adjacent riser pipe shoe V-arrangement tooth apparatus, gap is 8mm.
In use, V-arrangement tooth 4 can arrange soil at both sides preferably after pipe shoe enters stratum in the present invention, be convenient to riser pipe further under enter.And V-arrangement tooth 4 is installed bottom pipe shoe, it can be made to have in the earth formation preferably by property when not damaging pipe shoe.
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.
