Abstract
The utility model relates to a stabilizer, in particular to a hard stabilizer, which comprises a sleeve short section and six centralizing sheets which are welded at the pipe wall; the sleeve short section is made from the sleeve which is the N80 material, the centralizing sheet is made from the alloy of the silicon and the manganese and can replace the spring stabilizer in the operation of the fixed well such as the large slopping, the level well and the small space well to improve the sleeve centralizing effect when steady the well, to get the function that prevent from wearing and resisting, and prevent the centralizing sheet from falling off, and ensure the sleeve enters into the well smoothly.
Description
Technical field:
The utility model relates to a kind of centralizer, particularly a kind of rigid centralizer.
Background technology:
The sleeve pipe that is lowered into high angle hole, horizontal well, little gap well in the well drilling and cementing operation must be placed in the middle in well, for this reason, existing technology is generally used the spring leaf centralizer, realization is set upright, but because this centralizer is influenced by self structure, occur in the time of in the lower going-into-well of being everlasting damaging or welding coming off and circuitous resistance phenomenon, do not have centralizing function.
The utility model content:
The purpose of this utility model is in order to overcome above-mentioned shortcoming, and a kind of rigid centralizer is provided, and can substitute existing spring leaf centralizer, improves the casing centralization effect, can wear-resistingly not fall the tooth sheet during use, can improve cementing quality.
Technical solutions of the utility model:
For realizing above-mentioned task, the utility model adopts following technical scheme to finish, and it comprises by casing nipple and forming; Evenly welding six body resistance-strengthening tablets around tube wall forms.Described casing nipple material is made for the N80 sleeve pipe, and body resistance-strengthening tablets is silicon two manganese alloy steel material.
The advantage that the utility model compared with prior art has is:
Because this centralizer is formed with silicon two manganese alloy material by the body resistance-strengthening tablets of six strips, can evenly set upright sleeve pipe after going into the well, and have than strong anti-wear performance, not only improved down-hole casing effect placed in the middle, also can improve cementing quality, particularly result of use is obvious especially in big gradient, horizontal well and closely spaced oil well.
Description of drawings:
Accompanying drawing is the utility model structural representation.
Among the figure by 1, casing nipple, 2, body resistance-strengthening tablets forms.
The specific embodiment:
The utility model is provided by following examples, below in conjunction with accompanying drawing the utility model is described further.
Among the figure, casing nipple 1 one ends have 51/2 " public screw thread; the other end is 51/2 " box box cupling adopts the N80 casing nipple to be made, and is evenly welding the strip body resistance-strengthening tablets 2 of using silicon two manganese alloy steel material to form around the tube wall at its casing nipple middle part, every body resistance-strengthening tablets cross section, angle is 60 degree between the center, and body resistance-strengthening tablets 2 width are 27 millimeters, and length is between the 300-400 millimeter, 45 degree chamferings are arranged on its outward flange, can prevent the accident of damaging.
Claims (2)
1, a kind of rigid centralizer is made up of casing nipple (1); It is characterized in that: evenly welding six body resistance-strengthening tablets (2) around described casing nipple (1) tube wall and forming.
2, a kind of rigid centralizer according to claim 1, it is characterized in that: material is made for the N80 sleeve pipe, and body resistance-strengthening tablets (2) is silicon two manganese alloy steel material.
