摘　　要：随着水平井在油田勘探开发生产中应用的日趋广泛,需要储层在三维空间展布特征的精准刻画.以肇源南扶余油层为例,应用Petrel软件,采用井震结合岩相约束储层建模的思路,在岩—电对比建立等时地层格架的基础上,利用随机模拟方法建立了岩相和物性模型.建模结果符合研究区河流相沉积的地质特点,岩相、储层物性与地震数据的相关性很好,纵向上符合单井储层展布规律,横向上符合井间地震数据的趋势特征,准确地刻画了储层在三维空间的展布,为后期水平井部署提供了可靠的数据基础.建模方法为河道砂体储层建模提供了思路和经验.With the wider and wider application of the horizontal wells in the oilfield exploration and development, it is required that the fine characterization of the 3 D reservoir space distributing features. Taking Fuyu Oil Layer in South Zhaoyuan as an example, by adopting Petrel Software modeling integrated with the well and seismic survey results, the basis of the built isoehronous stratigraphic framework by and the thought of the lithofacies-constrained reservoir the lithofaeies and physical models are established on the petrologic and electrical correlation~ and further- more with the help of the stochastic simulation method. The modeled results accord with the geological characteris- tics of the fluvial facies sedimentation in the study area, the correlations between the lithofacies, reservoir physical properties and seismic data are greatly favorite, in detail, the spread and distribution laws of the single well reser- voir are accordant vertically, and the trend characteristics of the inter-well seismic data are conformed horizontally, thus the 3 D space distributions of the reservoirs are finely described, the reliable data bases for the later horizontal well deployment are provided. The model-building method provides a new idea and experience for the channel- sandbody reservoir modeling.
