Description
Technical field
The utility model relates to oil field blind plate technical field, is that one can Rapid Circulation blind plate device.
Background technology
Blind plate is the solid completion tool of one common in oilfield exploitation, because its intensity is high, good airproof performance and obtain applying comparatively widely at oily vapour Tian Jingzhong, but enter to be hampered after blind plate enters well under pipe string etc. hole condition time cannot set up circulation, blind plate can only be milled by boring milling, but because the time is long, complex operation, therefore in case of emergency just can not satisfy the demand.
Summary of the invention
The utility model provides one can Rapid Circulation blind plate device, overcomes the deficiency of above-mentioned prior art, and it effectively can solve blind plate cannot set up circulation fast problem when the hole condition such as being hampered.
The technical solution of the utility model is achieved like this: one can Rapid Circulation blind plate device, comprise connector drum, blind plate and shear pin, at connector drum internal fixtion, blind plate is installed, blind plate circumferentially has the inlet opening of at least two, the bottom of the blind plate inside inlet opening is provided with mounting groove, the sidewall of mounting groove is provided with the shear pin installing hole corresponding with inlet opening, be provided with shear pin at shear pin installing hole internal fixtion, the outer end of shear pin is positioned at inlet opening and blocks inlet opening.
As preferably, above-mentioned inlet opening is square or rectangle or circle, and shear pin is square or rectangle corresponding with it or circle.
As preferably, above-mentioned inlet opening is four and is uniformly distributed.
As preferably, the upper end of above-mentioned connector drum is provided with internal thread or external screw thread, and the lower end of connector drum is provided with internal thread or external screw thread.
The utility model is rational in infrastructure, easy to use, when encountering emergency, directly can build the pressure, shear pin be cut off, thus gets through circulation, solve burning issue, after processing, when according to circumstances directly can bore mill off blind plate or maintenance, reinstall shear pin.
Accompanying drawing explanation
Fig. 1 is that master of the present utility model looks half section structural representation.
Coding in figure is respectively: 1 is connector drum, and 2 is blind plate, and 3 is shear pin, and 4 is inlet opening, and 5 is mounting groove.
Detailed description of the invention
As shown in Figure 1, originally can Rapid Circulation blind plate device, comprise connector drum 1, blind plate 2 and shear pin 3, at connector drum 1 internal fixtion, blind plate 2 is installed, blind plate 2 circumferentially has the inlet opening 4 of at least two, the bottom of the blind plate 2 inside inlet opening 4 is provided with mounting groove 5, the sidewall of mounting groove 5 is provided with the shear pin installing hole corresponding with inlet opening 4, be provided with shear pin 3 at shear pin installing hole internal fixtion, the outer end of shear pin 3 is positioned at inlet opening 4 and blocks inlet opening 4.When encountering emergency, directly can build the pressure, shear pin 3 being cut off, thus gets through circulation, solve burning issue, after processing, when according to circumstances directly can bore mill off blind plate 2 or maintenance, reinstall shear pin 3.
As required, inlet opening 4 is square or rectangle or circle, and shear pin 3 is square or rectangle corresponding with it or circle.
As required, inlet opening 4 is four and is uniformly distributed.
For the ease of installation and removal, the upper end of connector drum 1 is provided with internal thread or external screw thread, and the lower end of connector drum 1 is provided with internal thread or external screw thread.
