Geological Modeling of Dual Porosity Igneous Reservoir in Chepaizi Oilfield in Junggar Basin

Abstract

Abstract: Based on the geological, seismic, logging, well test data and the structural modeling, the lithofacies, fracture zone, fracture density and fracture porosity models for dual porosity reservoir of igneous rocks in Chepaizi oilfield in Junggar basin are developed. Also, the structural system model for target zones with different sizes and scales are developed, including hydrodynamic and permeability models for dual porosity reservoirs based on the tectonic stress, imaging log, micro-seismic wave inspection and well test analysis, etc. These models can be used as guides for calculation of the reserves in such a reservoir in Chepaizi oilfield.

Key words: igneous rock, dual porosity reservoir, 3D geological modeling
