Abstract
The utility model relates to a lantern formula sleeve pipe centralizer belongs to the cementing tool. The novel spring piece weaving machine is mainly composed of two circular hoops (1) and a plurality of bow-shaped spring pieces (2), and is characterized in that a plurality of weaving holes (3) are formed in the circular hoops (1), a tongue clamping spring piece (4) is arranged on one side face of each weaving hole (3), and two ends of each bow-shaped spring piece (2) are respectively woven on the weaving holes (3) in the circular hoops (1) through the tongue clamping spring pieces (4). The welding type centralizer has the advantages of reasonable structure, simplicity in manufacturing, attractive appearance, firmness, durability, large centralizing force and simple and convenient production process, and overcomes the defects that the original welding type centralizer is easy to be subjected to desoldering and the production process of the weaving type centralizer is multiple.
Description
The utility model relates to a kind of Lantern casing stabbing board, relates to specifically a kind of spring leaf being woven in the casing stabbing board that its shape in the circular boop is used like the well drilling and cementing of Lantern, belongs to cementing tool.
At present, in the well drilling and cementing operation, employed casing stabbing board has two types, and a class is woven centralizer, and it is to adopt pin that the key chain is formed by connecting, and transportation, characteristics easy to use are arranged; Another kind of is the welded type centralizer, and it is spring leaf to be welded on the circular boop and the centralizer that forms, has and makes the advantage simple, that uprighting force is big.Yet from the situation of present use, this two classes centralizer all has its weak point, and woven centralizer production process is many, and after braiding is shaped, because it has intermittently, makes uprighting force that certain reducing be arranged; Sealing-off in use can take place because of spring leaf and circular boop not prison welding in the welded type centralizer, influences the well drilling and cementing quality.
It is that spring leaf is woven in the casing stabbing board that its shape in the circular boop is used like the well drilling and cementing of Lantern that the purpose of this utility model just is to design a kind of, to overcome the unreasonable and deficiency that causes uprighting force to reduce of existing structure.
The purpose of this utility model is achieved in that it mainly is made up of two circular boops (1) and multi-disc arcuate bombing leaf (2), it is characterized in that circular boop (1) is provided with a plurality of braidings hole (3), one side in each braiding hole (3) is provided with block tongue reed (4), and the two ends of every arcuate bombing leaf (2) is fixed on the interior braiding hole (3) of circular boop (1) by block tongue reed (4) braiding respectively.
Its feature is that also described arcuate bombing leaf (2) is Dan Gong, bouble-bow or three bow type spring leafs.
A plurality of braidings hole (3) that described circular boop (1) is provided with, its feature also are to weave between the hole (3) distance and equate, and axisymmetricly.
The utility model is compared with prior art: it is rational in infrastructure, make simple, handsome in appearance, firm and durable, uprighting force is big, production technology is easy, has overcome the many deficiencies of easy sealing-off of former welded type centralizer and woven centralizer production process, is the centralizer that a kind of well drilling and cementing that welcome by the user is used.
Below in conjunction with drawings and Examples the utility model is further specified:
Accompanying drawing 1 is the utility model outward appearance master TV structure schematic diagram.
Accompanying drawing 2 is the vertical view of the utility model Fig. 1.
Accompanying drawing 3 is the expansion front view of the utility model parts circular boop (1).
Accompanying drawing 4 is along the view profile at A-A place among Fig. 3.
Among the figure: 1, circular boop, 2, arcuate bombing leaf, 3, the braiding hole, 4, the block tongue reed.
As we know from the figure, it mainly is made up of the utility model two circular boops (1) and multi-disc arcuate bombing leaf (2), described arcuate bombing leaf (2) is Dan Gong, bouble-bow or the three bow type spring leafs that form through hot-pressing processing according to the needs of well drilling and cementing engineering with the 65Mn spring steel, and present embodiment is the diapsida spring leaf.Described circular boop (1) is suppressed on circular shaping dies after punch press is cut completion shape with the A3 steel plate and is formed, and circular boop (1) is provided with a plurality of braidings hole (3), and distance equates between the braiding hole (3), and axisymmetricly.One side in each braiding hole (3) is provided with block tongue reed (4), and the two ends of every arcuate bombing leaf (2) is fixed on the interior braiding hole (3) of circular boop (1) by block tongue reed (4) braiding respectively.
Claims (3)
1, a kind of Lantern casing stabbing board, it mainly is made up of two circular boops (1) and multi-disc arcuate bombing leaf (2), it is characterized in that circular boop (1) is provided with a plurality of braidings hole (3), one side in each braiding hole (3) is provided with block tongue reed (4), and the two ends of every arcuate bombing leaf (2) is fixed on the interior braiding hole (3) of circular boop (1) by block tongue reed (4) braiding respectively.
2, Lantern casing stabbing board according to claim 1, its feature are that also described arcuate bombing leaf (2) is Dan Gong, bouble-bow or three bow type spring leafs.
3, Lantern casing stabbing board according to claim 1, a plurality of braidings hole (3) that described circular boop (1) is provided with, its feature also is to weave between the hole (3) distance and equates, and axisymmetricly.
