摘　　要：沉积相揭示了目的层段的沉积环境、储集岩成因及其分布规律。通过沉积相研究,可以帮助油藏工程师建立油藏地质概念模型,为地震资料的数字处理解释奠定了基础。从在地质、测井分析的基础上,分析了地震属性与沉积相的关系,选取了敏感的属性,利用反射强度平面图,清晰地展现了分流河道、曲流河道等相特征,采用神经网络的方法对沉积相作精细划分,使井与井之间的结果更为客观,克服了以往人为推断划分的随意性。Sediment facies reveal the sediment environment of the interest inte rval,the origin and distribution rule of the reservoir. The reservoir engineers can build geological model of the reservoir according to the research of the se diment facies,and make a basis for the processing and interpretation of the sei smic data. On the basis of geological and logging analysis, we study the relatio nship of the seismic attributes and sediment facies and select the sensitive att ributes to lay out the facies characteristic of distributary channel and meander using reflect strength map. We use neural network finely to sort the sediment f acies which makes the interpretation between wells be more objective and overcom es the artificial haphazard in the conventional interpretation.
