Summary:The embodiment of the invention provides a carbonate rock bedrock background facies prediction method, device and equipment based on multiple wave fields. The method comprises the following steps: acquiring multiple wave field data of a carbonate rock target layer; determining full wave field post-stack wave impedance of the carbonate rock target layer by adopting a constraint sparse pulse inversion technology; the diffracted wave band wave limiting impedance and the low-frequency impedance body are fused to obtain diffracted wave field post-stack wave impedance of the carbonate rock target layer; determining reflected wave field post-stack wave impedance of the carbonate rock target layer by adopting a constraint sparse pulse inversion technology; performing three-dimensional data volume intersection analysis on the full wave field post-stack wave impedance, the diffracted wave field post-stack wave impedance and the reflected wave field post-stack wave impedance to determine a large-scale fracture-cavity re
