Flexible wellbore connection device

The utility model provides a flexible borehole connecting device, which comprises a flexible borehole connecting mechanism, the flexible borehole connecting mechanism comprises a borehole connector, a sieve tube arranged at the downstream of the borehole connector and a guide assembly, the guide assembly comprises a spherical sleeve nested in the sieve tube and a rotary inclined guide hinged to the spherical sleeve, and the rotary inclined guide is connected with the sieve tube through a connecting rod. The pushing mechanism comprises a central pipe and a first piston, the central pipe is concentrically arranged in the borehole connector, the first piston is fixed outside the central pipe, and a guide hole allowing drilling fluid to pass through is formed in the central pipe. According to the flexible well hole connecting device, the flexible well hole connecting device can be smoothly fed into the branch well hole when the curvature radius of the branch well hole is too small, and construction of the branch
