Abstract: Seismic atribute from seismic data is a series of characteristic parameters reflecting reservoir body and oil-gas bearing proper-ties. Any change of geologic body and its nature will lead to change correspondingly in seismic response infornation. The study of dynamic feature of seismic wave by using various seismic attributes allows to obtaining the type of geologic body, rock physical property, reservoir quality and their variations. The non-structural reservoirs are the strata, lithology and complex traps being indistinct in shape and feature and unable to be recognized by conventional methods in seismic profile. In view of such a reservoir, integrating with its seismic facies and other information, the seismic prediction of non-structural reservoirs in Jiyang depression is made, and good effects have been laken in its field 's exploration and development.

Key words: seismic atrbule, non-structural reservoir, seismic data, reservoir rock, oil-gas bearing property
