改进的基于目标的高精度沉积微相建模方法在苏14加密实验区的应用
Application of the improved obj ect-based method of high resolution microfacies model to infilled wellblock Su1 4,Ordos Basin,China
摘要
Abstract
The geological,well logging and seismic data in the Sulige area of Ordos Basin are studied in order to establish a microfacies modeling method suitable for the area.Reservoir lower limit standard is determined by shale content model derived from logging constrained inversion on the basis of geological model which collaboratively simulated the wave impedance and shale content. The parameters of the obj ect-based modeling are obtained on analysis of the dimension and distribution of sandstone based on the lithofacies model.Marked point process modeling method is used to build three dimensional high resolution microfacies model.Comparison of property models under different conditions indicates that property of mid-channel bar is better than that of point bar, and the microfacies of channel comes the last.The lithofacies-controlled model is stochastic as the model can not reflect expectation and variance of reservoir property of different microfacies.Three-dimensional microfacies model can be established with method mentioned above to reflect the plane and profile shapes of different microfacies as well as their contact relationship of the microfacies.The property model can represent features of reservoir property of different microfacies.关键词
