Abstract：Sand or shale content is an important lithologic parameter in oil geology research. The meaning of sand or shale content of seismic horizon is generally different from that of geologic horizon. When seismic horizons coincide with geologic ones，the meaning of sand or shale content of seismic horizon is the same as that of geologic horizon，and the content magnitudes indicate horizon generation environment.When they donut coincide each other，the sand or shale content of seismic horizon means sand or shale accumulated percentage thickness in the seismic horizon，but can not be used to interpret horizon generation environment directly. The sand or shale content of seismic horizon relates to both horizon generation environment.
