Logging curve interpretation method and device

The invention discloses a logging curve interpretation method and device. The method comprises the following steps: respectively reconstructing a value domain of an obtained longitudinal wave velocitylogging curve and an obtained density logging curve of a target reservoir, filtering the density logging curve after the reconstruction of the value domain to obtain compaction trend information of the target reservoir, subtracting the compaction trend information of the target reservoir from the longitudinal wave velocity logging curve after the reconstruction of the value domain to obtain a high-frequency velocity logging curve, determining a fluid characteristic curve according to the high-frequency velocity logging curve, and further determining the distribution of pore fluid of the target reservoir. The direct current component of the density logging curve indicates the compaction trend information, the fluid characteristic curve indicates the velocity dispersion characteristic, thecompaction trend informati
