Abstract
The utility model relates to a slips structure, the especially single deck tape -recorder that is used for on a packer tile structure belong to fracturing field under the oil well. An upper surface is the arc surface, is equipped with ceramic slip insert on the arc surface of single deck tape -recorder tile structure of packer, the slips body. Ceramic slip insert be six, per two ceramic slip insert's horizontal spacing is 20mm, vertical interval is 13mm. Ceramic slip insert and arc surface become 15 jiaos of interference fit and inlay on the arc surface. There are two pilot holes at the both ends of the slips body. Preferably, the both ends of the slips body have the two rings connected in star respectively. The utility model discloses a single deck tape -recorder tile structure adopts aluminium alloy material, has structurally increased by 2 slip insert, and is slightly longer than ordinary slips in the length, so not only strengthened anti temperature compressive property, has improved anchor packer's bulk strength moreover greatly, makes the bridging plug can sit at the assigned position more firmly.
Description
Technical field
The utility model relates to a kind of slips structure, and especially a kind of single deck tape-recorder tile structure on packer, belongs to oil well fracturing field.
Background technology
Along with world's main oilfield enters the middle and later periods of exploitation, in order to the various difficult problems occurred when solving actual exploitation, guarantee the high and stable yields in oil field, each main produce oil state of the world all increases the R&D intensity of Petroleum Down-hole Tool.In staged fracturing process, slips serves the important function set.Current slips length and intensity are all inadequate, so high strength slips of the present utility model arises at the historic moment.
Utility model content
For above-mentioned the deficiencies in the prior art, the utility model provides the single deck tape-recorder tile structure that a kind of length is longer, intensity is higher.
For achieving the above object, the technical solution adopted in the utility model is: a kind of single deck tape-recorder tile structure of packer, and the upper surface of slips body is arc surface, and arc surface is provided with ceramic slip insert.
Preferably, described ceramic slip insert is six.
Preferably, the horizontal spacing of every two ceramic slip inserts is 20mm, and vertical spacing is 13mm.
Preferably, described ceramic slip insert becomes 15 ° of angle interference fit to be embedded on arc surface with arc surface.
Preferably, there are two pilot holes at the two ends of described slips body.
Preferably, the two ends of described slips body have two annular grooves respectively.
Single deck tape-recorder tile structure of the present utility model adopts aluminum alloy materials, structure adds 2 slip inserts, longer than common Carvalho in length, so not only increase temperature resistance compressive property, and substantially increase the bulk strength of anchor packer, bridging plug is more firmly set at assigned address.

Detailed description of the invention
Embodiment
As shown in Figure 1-Figure 3: a kind of single deck tape-recorder tile structure of packer, the upper surface of slips body 7 is arc surface 1, and arc surface 1 is provided with six ceramic slip inserts 2.The horizontal spacing of every two ceramic slip inserts 2 is 20mm, and vertical spacing is 13mm.Described ceramic slip insert 2 and arc surface 1 one-tenth 15 ° of angle interference fit are embedded in (in Fig. 2 label 6 indication place) on arc surface.There are two pilot holes 3 at the two ends of described slips body 7, for injecting PUR the central tube of slips Standard at packer.The two ends of described slips body 7 have two annular grooves 4 respectively.Nine such single deck tape-recorders watt just form a circle and are enclosed within the core barrel of packer, and arc surface 1 achieves the combination with outer tube wall better in cylindric.Two garter springs are set in annular groove 4 respectively, nine slips lopping are fixed.Slips body 7 becomes 19 ° of angles (in Fig. 2 label 5 indication place) with the inclined-plane of packer cone contact with vertical curve.19 ° of angles are convenient to cone lower end and are embedded, and cone pushes slips group gradually downwards and makes it set smoothly on outer tube wall as the pressure increases.
