Study On The Architecture Model Of The Fan-delta In Kongdian 1th Formation Of Wangguantun Oilfield

The study of the sedimentary reservoir architecture of the fan-delta is in its infancy.The focus of the research is to restore the spatial distribution characteristics of the fan delta reservoir and explore the distribution of remaining oil.Therefore,based on the analysis of the complex sand bodies and the analysis of single sand bodies in the fan-delta front of the Guan 195 fault block in Wangguantun Oilfield,the dissertation studies the architecture models of different hierarchies.According to the architecture boundary-based method,the single sand body architecture model of the fan delta front is established under the constraints of the complex sand body architecture model.Finally,property models of the Guan 195 fault block are established under the control of the single sand body architecture model.Research has shown that the small layer of ZaoV6 and ZaoV7 in the Guan 195 fault block is deposited on the front of the fan delta and is divided into six single sand layers.The muddy deposit at the boundary of the the complex sand body is a stable continuous barrier layer,and the muddy deposit at the boundary of the single sand body is a microlocal stable continuous barrier.Based on the architectural boundary sedimentary body constraints,a single sand body architecture model of the fan-delta front was established based on the recognition anatomy of the complex sand body and single sand body architectural unit.Under the constraint of the single sand body model of the fan-delta front,based on the data relationship between porosity and permeability,the porosity model was calculated to obtain the conversion synergic property,and the conversion synergic property was used as the coordinational attribute to establish the permeability model.
