The Research Of Three-dimensional Geological Modeling Applied In Oil Field Exploitation

The study of reservoir modeling was an important technology and tool in reservoir visualization and quantitative in recent years.It quantitatively characterized reservoir and depicted various scales heterogeneity by building three-dimensional geological model of reservoir structure,micro facies and physical properties,based on prototype geological knowledge database including all kinds of information.In this paper the research object is Chang8delta-front facies reservoir of Upper Triassic Yanchang formation in Jiang jiachuan area of Zhiluo oilfield,Ordos Basin.With sedimentology and logging geology theory,we have analyzed a single well core and logging facieS,studied on plane distribution and its evolutionary law of every thin zone-Chang81,Chang82-sedimentary micro facies. The paper has been constructed abundant geological knowledge database of different types geological bariables combining with multi subjects,on which based the author constercted three-dimensional geological model of sedimentary micro facies,framework of sand body,porosity and permeability of Chang8of sedimentary facies according to the method of multiple information cooperative stochastic modeling by means of the software of Petrel as well as geological statistics and stochastic simulation.
