While-drilling seismic data acquisition device

The invention discloses a while-drilling seismic data acquisition device, and belongs to the technical field of seismic data acquisition, and the while-drilling seismic data acquisition device comprises a seismic wave acquisition unit which comprises a first geophone, a second geophone and a third geophone, the first geophone is arranged at a surface wellhead, and the second geophone and the third geophone are both arranged at the surface; the first detector, the second detector and the third detector are located on the same straight line; the first detector is used for collecting a vibration signal generated when a drill bit collides with a rock and converting the collected vibration signal into a first electric signal, and the second detector is used for collecting a vibration signal generated when the drill bit collides with the rock and converting the collected vibration signal into a second electric signal. The third detector is used for collecting a vibration signal generated when the drill bit collides
