effect
1 When drilling, the kelly cooperates with the center of filling and the center of the turntable to transmit the ground rotation torque to the drill pipe to drive the drill string and the drill bit to rotate;
2 withstand the full weight of the drill string;
3 channels for drilling fluid circulation.
structure
The kelly consists of upper and lower joints and a tubular body. The pipe body part is a square or hexagonal structure (the oil drilling is mostly a square structure); the upper joint is a left-handed female thread (reverse buckle), which is connected with the faucet, and the left-handed female thread prevents the reverse buckle during the rotation; the lower joint It is a right-handed male thread and is connected to the drill pipe. When working, the upper end of the kelly is always above the turntable surface, and the lower part is below the turntable surface.
