It is interference fitted between inner wall.
The directional well windowing auxiliary tool, the curved baffle of the upper sleeve upper end are in the deflecting of whipstock 1
On the downside of face.
The auxiliary tool the utility model has the beneficial effects that a kind of directional well described in the utility model opens a window, by setting
Setting of casing and upper and lower two rubber ring are set, can not only realize that the limit to whipstock pedestal is fixed, but also effectively avoid landwaste, iron filings
In into the annular space of whipstock pedestal and casing；By the upper casing of setting and card slot, not only can just whipstock it is more accurate
Contraposition calibration effectively is carried out with whipstock pedestal, and landwaste, iron filings is effectively avoided to be contacted with whipstock, whipstock is caused to damage
It is bad；By the way that curved baffle is arranged, barrier can be carried out to landwaste, iron filings since deflecting surface, landwaste, iron filings is effectively avoided to enter ring
Cause whipstock stuck in shape space；By the way that groove and pulley is arranged, more convenient can be effectively performed whipstock stretch into and
It salvages；By the way that undergauge ring, fixinig plate and elasticity bolt is arranged, casing may make to carry out firm be fixed by socket with whipstock；
The utility model is simple in structure, easy for installation, can not only realize the dual barrier to landwaste, iron filings, and landwaste, iron filings is avoided to enter
The stuck damage of whipstock is caused in annular space, and great convenience is provided to the installation and salvaging of whipstock, is directional well
Windowing task provide strong support.

Specific implementation mode
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
Directional well windowing auxiliary tool in conjunction with given by attached drawing 1~2, is equipped with whipstock on 2 inner bottom surface of described sleeve pipe
Pedestal 9 is socketed with setting of casing 8 compatible with the whipstock pedestal 9, in the setting of casing 8 on the whipstock pedestal 9
Outer surface upper and lower ends be respectively equipped with upper rubber ring 7 compatible with 2 internal diameter of described sleeve pipe and lower rubber ring 10, it is described to trap
It is interference fitted between 2 inner wall of the upper rubber ring 7 of 10 upper and lower ends of pipe and lower rubber ring 10 and casing, in the setting of casing 8
7 upper surface of upper rubber ring of upper end is equipped with card slot 14, whipstock 1 is equipped on 9 top of whipstock pedestal, in the deflecting
Upper casing 4 compatible with the card slot 14 on 7 upper surface of upper rubber ring is socketed on 1 outer surface of device, in the upper casing 4
Outer surface upper end is equipped with curved baffle 3 compatible with 2 inner wall of described sleeve pipe, at the curved baffle 3 of 4 upper end of upper casing
On the downside of the deflecting surface of whipstock 1, it is spaced on 4 outer surface of upper casing and is orderly equipped with several grooves 11, described several
It is equipped in groove 11 and carries out clearance fit idler wheel 5 with 2 inner wall of described sleeve pipe, open type knot is equipped at 4 middle part of the upper casing
