The invention discloses a
coiled tubing wellhead quick connecting device with a hydraulic
flange, which belongs to the technical field of
petroleum equipment and comprises a blowout prevention
pipe connecting piece, a hydraulic connector and a hydraulic clamping
system. The upper end of the blowout prevention
pipe connecting piece is provided with a standard union joint which is quickly connected with a blowout prevention box or a blowout prevention
pipe; a first step matched with the hydraulic connector is arranged at the lower end of the blowout prevention pipe connecting piece, and the lower end face of the first step is used for axial limiting of the blowout prevention pipe connecting piece. A
flange plate connected with an external
flange is arranged at the lower end of the hydraulic connector; and the hydraulic clamping
system is used for locking or unfolding the blowout prevention pipe connecting piece and the hydraulic connector. The continuous pipe
well control connecting equipment is safely and rapidly mounted and dismounted in a
hydraulic control operation mode, and the situation that operators manually
mount and dismount the
well control equipment in a long-time and high-strength mode when the operators are exposed to the lower portion of a hoisting injection head is avoided.
