Abstract

Abstract:

Featuring in deep burial depth,large lateral variation,and small single layer thickness,the beach bar sand reservoirs in the 4th member of Shahejie Formation is an important type of lithological deposits.Integrated utilization of seismic,geology and drilling data is important to the prediction of this kind of reservoirs.After years of exploration practices,a series of techniques,including palaeosedimentary environment reconstruction,forward modeling,seismic attribute analysis and geologic target-oriented inversion,has taken a complete shape in Shengli Oilfield by aiming at beach bar reservoir prediction.These techniques are employed in the exploration of the beach bar sand reservoirs in Boxing subsag of Dongying sag and the results are quite encouraging.

Key words: shore-shallow lake facies, beach bar sands, palaeosedimentary environment reconstruction, seismic attribute analysis, reservoir prediction, Dongying sag
