多点地质统计学研究进展与展望

Progress and prospect of multiple-point geostatistics

在简要回顾多点地质统计学起源后,介绍了多点地质统计学的3种方法,并总结了多点地质统计学的研究进展。在应用领域,已经从河流相建模发展到扇环境建模,从储集层结构建模发展到储集层物性分布模拟,从宏观地质体预测发展到微观孔喉分布建模,从地质研究发展到地质统计反演。在整合信息建模方面,给出了3种综合地震属性的方法;在算法方面,提出了PRTT实时处理方法,完善了多点地质统计学建模,并开发了新的多点统计生长算法(Growthsim)。对多点地质统计学未来发展进行了展望,指出在训练图像、数据综合以及建模方法耦合方面还需要进一步深入研究。

The paper summarizes the progress of multiple point geostatistics.First the origin of multiple point geostatistics is introduced and the theories of three main multiple-point geostatistic methods are analyzed.Then,the development status is concluded in three aspects.Firstly,in real reservoir modeling domain,the modeling environment is from fluvial to fan facies;the modeling content is from reservoir architecture to reservoir petrophysical property;the modeling scale is from large geologic deposits to micro pores and throats;the modeling region is from geological modeling to geological statistic inversion.Secondly,in integrating multi-disciplines modeling domain,there are three methods for integrating seismic data.Thirdly,in modeling methods domain,there are some improvements and new methods such as PRTT and the Growthsim.Based on the analysis of the development of multiple point geostatistics,the paper points out that the training image,data integration and modeling coupration are the main aims in further studies.
