摘要
The paper,taking the S Ⅱ12 layer of Saertu Oilfield as an example,provided a modeling method to construct the three dimensional architectural model of high sinuous distributary channels on delta plain. According to the sedimentary hierarchy and the migration mechanisms of meandering river,the architecture elements of the sinuous distributary channel such as point bar and inclined heterolithic stratification are recognized. The geometry and statistics parameters of inclined heterolithic stratification are extracted and the mathematical function are formed by elliptical function in horizon and line function in profile. Then,the three dimensional architectural model of the high sinuous distributary channels constructed by two steps: first,using the sequential indicator simulation to construct the model of the high sinuous distributary channels and associated microfacies; second,the inclined heterolithic stratification is modeled and embedded under the constrains of the distributary channels. The properties models are constructed by the final architectural model and show the barriers of inclined heterolithic stratification which affect the flow of the oil and water. So the models will contribute to the reservoir simulation and enhancement of remaining oil.
