Zhidan Oilfield Of Jinding Yi Daxigou Oil Head Of Reservoir Modeling,

The article discusses the structure characteristics, the sand body shape and distribution and the mcrofacies feature of Chang-6 Oil Set, analyses the physical properties and heterogeneities of the reservoir which is classified three types, summarizes the relation between microfacies, sandbody distribution and physical properties.the present paper deals with the division of the permeable units made by using the reservoir flow layer indicator(FZI)values, and the relationship between the genetic sandstones and the permeable units, by using RMS which is a kind of software to set up a geological modeling, set up the geological modeling of the Shuang'heChang — 6 Reservoir in Zhidan Oil Field,and it shows the underground geological character correctly and externally, reveals the collecting rule of oil and gas,becomes the base of developing this reservoir efficiently and accurately.Production and main cognition:Recognize four kinds of microfacies in researeh area including underwater distributive river course estuarine bar.etc.The underwater distributive river course is Preponderant and it is the main reservoir in research area.The study on reservoir shows that the shuanghe Chang-6 Reservoir in Zhidan Oil Field has the pore structure of big pore and small throat,represents middle porocity and less permeability;has two kinds of interlayers including shale interlayer and calcareous interlayer,and they have different electric log curves character;and sedimentary and diagenesis are the main factors to lead the heterogeneity of this reservoir.By using clustering analysis study on reservoir classification and the compartmentalization of flow unit the results shows that the microfacies decides the distribution of sand body, properties of matter, oil saturation, and the results of reservoirclassification and the compartmentalization of flow unit.They are matching.Set up the 3-D geological model of the Shuanghe Chang-6Reservoir in Zhidan Oil Field by using V-RES, reveal the3-D distribution character of there search area structure, sand body, Porocity, Permeability, and Oil saturation, and become the base of dynamic digital modeling in the future.
