Application of Reflection Strength Slope to Identification of Sequence and Sedimentary Environment

Abstract

Abstract: Base on core and well log comprehensive analysis and the sensitivity of the slope of reflection strength of seismic attributes to depositional sequence, the sedimentary facies in sand-shale member of Bachu formation of Lower Carboniferous in Tahe oilfield of Tarim basin is studied, identifying flood tidal delta, coastal shoreface sand, lagoon and barrier island etc. from lateral variation map of reflection strength slope and sedimentary cycle correlation. The identified results are closer to real situations than those from utilizing the seismic attributes.

Key words: sedimentary facies, seismic attribute, reflection strength slope, flood tidal delta, barrier island
