摘要
Taking the meandering river reservoir in Daqing Oilfield as an example,this paper comparatively studies the reservoir modeling using indicator Kriging,sequential indicator simulation and multiple-point geostatistics by the selection of the most suitable algorithm.Based on this,the selected modeling methods are determined,which can serve for oilfield production.The results shows that the IK method gives the best continuous sand body and a bull-eyes mudstone,which is a smooth effect and the distribution area of mudstone is small;the sequential indicator simulation method effectively overcomes the smooth effect and weakens the features of bull-eyes mudstone with the worst continuous sand body;the multiple-point geostatistics method gives a comparable continuous sand body,which reflects the distribution characteristics of river and avoids the smooth effect,thus the established model is much more objective and accurate.This study can provide a basis for selecting the modeling method and a geologic model with high precision.
