摘　　要：砂体展布规律是油层储藏研究的热点和重点。采用分形差值方法对砂体的展布规律进行研究,从全新的角度为油气的勘探、开发提供更多的信息。分析论证了使用分形插值方法研究砂体展布的可行性,并根据对渤南六区沙三段砂体的物性特点的分析,利用地质、岩芯和测井资料,建立了砂体展布规律预测模型,对砂体展布规律进行了预测,进一步结合该地区的沉积环境和沉积相,对渤南六区沙三上段储层有利区块进行了分析,结果与工程实际较为吻合。The rule of sand-body distribution is a hot topic in the oil reservoir field. Fractal interpolation theory is applied to delineate the sand-body distribution of the study area. It provides more information from a brand new angle for the oil ＆ gas exploration and development. It analyzes and provides the feasibility that fractal interpolation theory is used to sand-body distribution, as well as the technical route with this mothod. A model is constructed by using three dimensional fractal interpolation function, geology, core and logging data , with the aid of the techniques of sedimentary environments and facies for the prediction of the sand-body extension. The result of research in study area is more consistent with favorable area of the upper Es~ formation in the sixth block of Bonan oilfield.
