Matlab and Geoscope Joint Inversion Technology under the Constraint of Isochronous Facies Controlled Multi-Point Geological Model

Abstract:

The formation in Wudong area is complex, and oil and gas reservoirs are seriously concealed and very difficult to identify. Thus, to accurately predict the sand bodies by using seismic data, the facies controlled multi-point geological statistical model constrained inversion technology under the isochronous framework is applied. Through a comprehensive explanation on the seismic and geological data, the deposit facies space distribution in the study area is reveled, and then a very stable space variation function is solved in combination with the multi-point geological statistical model analyzed in the developed well. Seismic stochastic inversion constrained by the model is implemented, and its prediction accordance rate of the sand bodies reaches 87.5%, proving the facies controlled multi-point geological statistical model constrained inversion technology under the isochronous framework are only targeted at a few wells, and plays a very significant effect on the area of few wells, uneven distribution, and complex formation evolution. Thus, the model can meet the needs of the oil field exploration and development.
