摘　　要：综合运用岩心观察、薄片鉴定、物性分析、测井分析及录井分析等技术手段对准噶尔盆地中部Ⅰ区块三工河组低渗透储层的沉积特征和成岩作用特征进行研究,划分出7种岩相类型和7种成岩相类型。将岩相类型与成岩相类型进行合理组合,共在研究区划分出12种沉积成岩综合相类型。在此基础上,利用自然电位、自然伽马、声波时差、密度、补偿中子及深感应电阻率测井曲线的组合特征,采用Fisher典型判别建立各沉积成岩综合相的定量判别函数、建立了测井参数交会图版、标定了单井沉积成岩综合相,并对识别结果进行了检验。将薄片鉴定与测井识别结果相结合,对单井沉积成岩综合相类型进行精细划分,对研究区储层沉积成岩综合相类型的分布规律进行预测。Based on bulk analyses of core observation,thin section identification,physical analysis and logging analysis,this paper studied the lithologic features and diagenesis in low permeability reservoir of Sangonghe Formation in block 1of central Junggar Basin,divided seven lithofacies and seven diagenism facies.Through reasonable combination with lithofacies and diagenism facies,the authors divided twelve sedimentary-diagenetic synthetic facies in the study area.On this basis,using the logging curve characteristics of spontaneous,natural gamma,interval transit time,density,compensated neutron and deep lateral resistivity,the Fisher typical discriminant was adopted to determine the quantitative discrimination functions of each sedimentary-diagenetic synthetic facies Cross-plot of logging parameters was established,and sedimentary-diagenetic synthetic facies of each well were calibrated and the correctness of the identification result was tested.Combined thin section identification with logging identification results,this paper analyzed sedimentary-diagenetic synthetic facies of each well meticulously and predicted the distribution of the reservoir sedimentary-diagenetic synthetic facies in the study area.
