  • Information transmission apparatus for logging while drilling
    Patent number: 9816327
    Abstract: An information transmission apparatus for logging while drilling comprises a hollow drilling rod and at least one cable. The drilling rod comprises at least one first drilling rod member and at least one second drilling rod member spliced to each other alternately. The first drilling rod member comprises a through hole, and the second drilling rod member comprises a stepped hole. The cable comprises a fixed end, a connected end, and a folded portion connect the fixed end to the connected end. Each of the cables is fixed in the stepped hole through a fixed end or is connected to a connected end of an adjacent cable. The connected end may be stretched along the stepped hole, and stretched through the through hole to be electrically connected to a logging instrument or a fixed end of the adjacent cable. The apparatus provides protection for a cable through a hollow drilling rod, thereby improving the transmission reliability.
