Stratal Slicing technology is a common method of 3D seismic data interpretation, studying its physiognomy and lithologic characteristics by acquiring variation characteristics of the seismic attributes on the plane. The purpose stratum in the study area is wedged, it is more proper to use stratal slicing than time slicing and horizontal slice. Based on stratal slicing technology, this paper characterizes the Akshabulak formation sedimentary system in block D of South Turgai Basin, Kazakstan. The results show that, making clear of the seismic attributes on behalf of the depositional facies combine with stratal slicing and regional depositional environment can judge that the block D develops fluvial deposit and delta deposit, Another finding is that by using stratal slicing can characterize channel‘s boundary, plane geometry and discontinuity accurately. |
