Description

Technical Field

[0001] The utility model relates to the technical field of floating hoop and floating shoe, in particular to a floating hoop and floating shoe with anti-falling function. Background Art

[0002] The float collar and float shoe with anti-fall design is a specially designed downhole tool, which is mainly used to provide buoyancy, making the installation of casing more convenient during drilling. This design effectively prevents the problem of overall inversion and loosening during drilling operations by adding side wings to the float collar and float shoe.

[0003] In actual use, the drain port of the existing floating collar and floating shoe is easily blocked by mud, sand and gravel. When the device is moved underground, blockage occurs and the device needs to be pulled upward again. During the process, it is more cumbersome to deal with the blockage. Therefore, it is necessary to provide a floating collar and floating shoe with an anti-falling function to prevent the drain port from being blocked and affecting the normal use of the device in the well.
