Abstract:

For the carbonate ancient karst cave reservoir prediction problems of the strong heterogeneity in the vertical and
horizontal direction,we carried out the three-dimensional seismic reservoir prediction technology research under the guidance
of ancient karst geology theory. We put forward the concept of seismic palaeokarst science and expounded the basic viewpoints,
research contents,technical route,development trends,and research significance. Seismic Palaeokarst study is a set of
knowledge system,which is based on the high-precision three-dimensional seismic techniques. Through the seismic forward
modeling and well seismic calibration,the seismic identification model of ancient karst cave is established,and the favorable
zones of the palaeokarst caves reservoir is predicted,and favorable exploration targets are selected optimally. It has an important
guiding role to the exploration of palaeokarst carbonate fractured-vuggy reservoirs. Taking the carbonate fractured-vuggy
reservoirs in Tahe oilfield as an example,the application and effects of seismic Palaeokarst is proved.

Key words: seismic palaeokarst, three-dimensional seismic exploration techniques, palaeokarst geological theory, prediction
