Reservoir Prediction of Lishui Depression, East China Sea Basin

Abstract

Reservoir plane features of Lishui depression in East China Sea Basin is analyzed with multiattribute analysis. Through the production of fine synthetic seismograms, the research area is analyzed by seismic attribute. On the basis of the calibration of synthetic seismograms and interpretation of horizon, accurate corresponding relation between the seismic reflection and geological horizon is established. By means of multiple attribute extraction technology, relatively independent attributes related to oil and gas are selected, and afterwards the analysis of the petrophysical characteristics and the optimization of the seismic attribute are achieved. Finally, through the seismic attributes analysis technology and the horizon slice technology, and seismic inversion is conducted, the favorable areas of oil accumulation are predicted.
