Application of Quasi-Acoustic Seismic Inversion to Prediction of Glutenit Reservoir in Inshore Submarine Fan—An example from Dongying sag

Abstract

Abstract: The selected well logs that are sensitive to the effective glutenite body are analyzed using the seismic data of 3-D prestack time migration in regional range of 600 km2 and drilling-logging data of Eogene Shasixia member (Es4) in Dongying sag of Jiyang depression basin. The 3-D seismic data volume is processed and reconstructed by means of quasi-acoustic inversion method reconstructed from well logs for the purpose of improvement of identifying ability on various effective glutenite reservoirs. The results show that the distributing interval of the effective glutenite seismic parameters is over 12 000, while exact glutenit bosy ranges form 10 000 to 12 000. Based on these results, the prediction of the effective glutenite reservoir of Es4 in inshore submarine fan in this study area can be made.

Key words: Dongying sag, inshore submarine fan, glutenite body, logs reconstruction, seismic Inversion
