Abstract
Aspects of the present disclosure relate to a downhole tool having a plurality of turbulence-generating channels. Other aspects of the disclosure relate to downhole tools having one or more ports. Embodiments further include methods for connecting the downhole tool to a wireline system and performing a pump-down operation where the plurality of turbulence-generating channels of the downhole tool create turbulence in fluid being pumped around the downhole tool, creating a force on the downhole tool in a downhole direction. Embodiments further include methods where a component moving in the cavity of the downhole tool unseals the opening at the downhole end of the substantially cylindrical body; and pulling the downhole tool in an uphole direction in the wellbore, wherein fluid in the wellbore passes through the port, into the cavity, and out of the opening on the downhole end of the downhole tool.
