Abstract
The utility model relates to a cementing head bumper pin used in a well fixing device in an oil field, in particular to a bumper pin rod for quickly assembling a cementing head. The bumper pin rod consists of a bumper pin shaft, a sealing ring, an intermediate sleeve, an external sleeve, a square rod, a nut, a rotary liner, a connecting sleeve and a press cover. The center of the bumper pin shaft is provided with an indication rod. The bumper pin shaft adopts a four-thread structure. The right end of the bumper pin shaft is provided with a positioning pin. The device shortens the rotation time of the bumper pin shaft, provides indication for the place from the bumper pin to limit positions, and does not change the bumper pin position during the well fixation construction, thereby shortening the time for rotating the bumper pin so as to continue the well fixation construction, without the leakage or low-velocity return of the cement slurry and with a well fixation rate of 100 percent.
Description
Technical field:
The utility model relates to the backing pin bar of the especially a kind of quick water receiving mud of cementing head backing pin in a kind of reinforcing oil well device.
Background technology:
At present, when oil well cementing, be installed in the backing pin bar above the cementing head, take out the required time length of bar rotation backing pin bar in the use and take out the limitless position indication of backing pin bar, in addition, easily cause backing pin bar change in location and move axially because of vibrating in the cementing operation, cause well cementation not construct continuously, miss, produce that cement is low to be returned phenomenon and influence cementing quality.
The utility model content:
The purpose of this utility model is a kind of backing pin bar that can connect cementing head fast that provides in order to overcome above-mentioned shortcoming, can shorten the backing pin rotational time in the construction, indication backing pin position, can in cementing operation, keep the backing pin position can not change, thereby well cementing operation is constructed continuously, can not occur in the construction that cement leakage is low to be returned phenomenon and can improve cementing quality.
The technical solution of the utility model is:
It is made up of backing pin axle, sealing ring, intermediate sleeve, overcoat, cubic bar, nut, pivoted housing, adapter sleeve, gland; Indicating arm is equipped with in its center of described backing pin axle, and the backing pin axle adopts the four-head helicitic texture, at backing pin axle right-hand member alignment pin is housed.During use, extract alignment pin earlier, rotate gland again, the four directions bar rotates the backing pin axle by top side's cover, thereby realizes the fast moving of backing pin, drives indicating arm simultaneously at moving process and moves right, when the indicating arm right-hand member is concordant with cubic bar, this moment, backing pin axle left end was also concordant with inner hole wall, illustrated that backing pin has reached the limit of the position, and then the insertion alignment pin prevents mobile getting final product.
The utility model compared with prior art has distinguishing feature.
Owing to adopt the four-head screw thread on the backing pin axle circumference cylinder, the backing pin axle is moved fast vertically, make below cement paste is pressed into plug, cementing operation can be constructed continuously like this, and the cement paste leakage can not take place, cause low returning, influence cementing quality, in addition, this device is equipped with indicating arm, make the backing pin extreme position that indication promptly be arranged, can prevent well that again pin causing the well cementation failure because of moving axially of vibration generation.
Description of drawings:
Accompanying drawing is the utility model structural representation.
Among the figure by 1, the backing pin axle, 2, sealing ring, 3, intermediate sleeve, 4, overcoat, 5, alignment pin, 6, cubic bar, 7, nut, 8, pivoted housing, 9, gland, 11, adapter sleeve, 12, indicating arm forms.
The specific embodiment:
The utility model is provided by following examples, is illustrated below in conjunction with accompanying drawing
Shown in the figure, backing pin axle 1 is a metal round rod, in the different-diameter sized passageways is arranged, cubic bar 6 and indicating arm 12 its cubic bars 6 are housed can make backing pin axle 1 rotate by a square cover, the four-head screw thread is arranged on the face of cylinder of backing pin axle 1, backing pin axle 1 is moved fast vertically, thereby realize the fast moving of backing pin axle, because indicating arm 12 is contained in backing pin axle 1 the inside, backing pin axle 1 moves and can drive the indicating arm fast moving, and when the indicating arm right-hand member was concordant with cubic bar 6 right-hand members, backing pin axle 1 left end was concordant with inner hole wall, this moment, backing pin reached the limit of the position, inserted alignment pin 5 at last and prevented to become flexible.At the skin of backing pin axle 1 intermediate sleeve 3 is housed and fixes, use jackscrew fastening at last again by screw thread and backing pin axle, two side positions of intermediate sleeve 3, overcoat 4 is equipped with at the step place, and adapter sleeve 11 links together with overcoat 4 and backing pin axle.Sealing ring 2 plays hermetically sealed case and intermediate sleeve 3 effects, in addition, between cubic bar 6 skins and backing pin axle 1 sealing ring is housed also.This device has shortened the used time of rotation backing pin, is provided with the backing pin extreme position and shows that alignment pin can be prevented pin because of moving axially that vibration produces, and can keep well cementation to construct continuously, thereby makes the well cementation factor of merit reach 100%.
