Abstract
Starting with algorithm designing, training image,and practical application,the authors analyzed multiple-point statistics research trends both in China and abroad. On such a basis, the core principles of the main four MPS algorithms, their applicable ranges and advantages as well as disadvantages were analyzed,so as to forecast the trend of reservoir modeling. Multiple-point geostatistics is an international forefront research tool in stochastic modeling; nevertheless, as the algorithm is not yet mature, it should be further improved. On the basis of previous researches, the existing problems of the multiple-point geostatistics that need to be modified and the direction of the processing of training images are proposed, such as suitable processing of training image, choice of similarity methods, choice of standardized data,smoothing,coupling among algorithms,and expansion of the simulation extent for fractured-vuggy carbonate reservoir. In order to improve the usage of multiple-point geostatistics for reservoir stochastic modeling,we should spare no efforts to increase the simulation area,improve simulation accuracy,expand the scope of simulation of reservoir types,save simulation time and improve simulation efficiency.关键词
