Abstract We systematically analyze the coseismic response characteristics to 2 earthquakes in the far field and 4 medium-strong earthquakes in the near field of the Dahekou, Zhouping, and Guojiaba wells in the Three Gorges reservoir area. Difference analysis is carried out. In addition, we compare the seismic reflection capability of these three wells with respect to seismic energy density, coseismic response amplitude and magnitude, and well seismic distance. The results show that: 1) Dahekou well has stronger reflection ability than the other two wells. 2) The coseismic response of the far-field water level of the three wells may be caused by the far-field wave triggering. The near-field coseismic response is mainly due to the regional crushing stress, and is also affected by the lithology and the fracture structure of the wellbore.
