Geological Modeling Of Chang6~1Resevroir In Shazegou Area

In order to have a integral and in-depth understanding of Chang6Reservoir in Shazegou, Panlong oil Field, to offer a storng foundation for the next excavation of remaining oil and enhance the recovery ration of oil reservoir. Based on theories of sedimentology, tectonic geology, petroleum geology, logging geology, mathematics and the geological statistics, take modern computer technology and geological modeling software as the method, and comprehensive dynamic and static information that from drilling, logging, and well testing, analytical data and drill stem test, subzones of Chang61reservoir layer are fine divided and compared, structure features are explained, and deposition micro-phase type, evolution law of deposition micro-phase, plane distribution features and exhibition of sand body of region of interest are analyzed, from core analysis to key well research, micro-to macro, and intra-layer to inter-layer, petrological features of reservoir layer with type and relationship of pore-throat was researched, and reservoir heterogeneity was evaluated. Type, driven energy and type temperature and pressure system distribution law of oil pool with fluid property are cleared. Finally, used of stochastic modeling methods and petrel software, the geological model of structure, sedimentary facies and reservoir property are established, and verified that it is reasonable, provided the geological basic for preparation of development program and the next reservoir numerical simulation.
