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.
