Analysis on the well Constraint Inversion of the Jason-Based Layer Flattening Seismic Data under the High-Resolution Isochronous Framework

Abstract:

The later-period structure of Fuyang oil layer is very complex, and its reservoir mainly consists of riverway sand bodies; the oil and gas reservoir is significantly concealed, so it is greatly difficult to identify. In order to accurately predict sand bodies by using seismic data, a well constrained inversion is made to the layer flattening seismic data using Jason software under the high-resolution sequence framework. Through a comprehensive analysis on seismic and geological data, the absolute error is within ±500, the relative error is within 10%; the predicted sand body plane distribution is reasonable, and the absolute error of 82% sand bodies is less than 10%. This proves that well constrained inversion for the Jason-based layer flattening seismic data under the high-resolution isochronous framework has an obvious effect on the areas of complex later-period structure, and thin and complex changed sand bodies. Therefore, it can meet the needs of the oil field exploration and development to a certain extent.
