摘　　要：砂砾岩储层发育受岩性岩相控制,开展砂砾岩岩性岩相识别具有重要的意义。利用丰富的测井资料识别岩相,对岩相类型及指示标志研究,岩心观察表明:玛北砂砾岩为扇三角洲沉积,发育5类亚相;不同亚相岩性及结构构造特征显著不同,可以作为岩相识别的标志。并建立了常规资料识别岩性的交会图版,FMI资料识别结构和构造的模板,利用该图版对玛北砂砾岩岩相进行了有效识别,将为砂砾岩地震储层预测提供标定。The development of glutenite reservoir is controlled by lithology and lithofacies,so,to carry out the identification of lithology and lithofacies of glutenite has the vital significance.In order to indentify the lithofacies with logs,firstly lithofacies types and marks was investigated,according to the core observation,the glutenite of Mabei is taken as fan delta deposits and has five types of subfacies.Different subfacies has significantly different lithology and structure characteristics which can be used as marks of lithofacies identification.Secondly,the crossplot is established by using the conventional data to identify lithology and identification model for identification of structure and texture was built with the FMI data.Finally,glutenite facies of Mabei area were effectively identified by using this method,which will provide a calibration for the seismic prediction glutenite reservoir.
