A vector information based multiple-point geostatistic method
Take Snesim as algorithm foundation,a new multi-point geostatistics algorithm VMPS was presented on the basis of geological vector information.Taking alluvial fan as an example,the alluvial fan geological vector coordinate system was constructed,the geological vector information was integrated in training images,and the vector information based training images was formed.Then,the scanning mechanism for training images was improved,and the search tree was established based on the geological vector information with the vector information statistics events and regional conditional proportion between provides areas.In the simulation process,based on the vector information of the current simulation area,the data event was extracted to calculate the repeat numbers,so as to get the conditional probability distribution which fulfills the condition of local stability and establishes models that can reproduce different characteristics of different area.The ideal models and actual reservoir simulation test show that the simulation effect of VMPS is superior to that of Snesim,as VMPS can be applied to the reservoir modeling under the "non-stationary" conditions.
