【摘要】 充分利用钻井、测井、地震资料，以计算机自动化为手段，建立了储层沉积微相制图四项基本技术。通过在大庆长垣以西地区应用，基本搞清了中部含油组合各层段的沉积微相展布特征。结合试油资料，从沉积微相角度预测了岩性圈闭有利区，识别出１９１个岩性圈闭，有效地指导了勘探工作。更多还原

【Abstract】 Making full use of drilling and logging and seismic data, the paper establishes four basic techniques about the sedimentary microfacies of reservoir by means of automation. By the application of the techniques in the west area of Daqing Changyuan, sedimentary microfa-cies distribution characteristic of every layer of middle oil - bearing stratum is clear. Combining with test petroleum data, the favorable area of lithologic traps are predicted according to the sedimentary microfacies, and one hundred and ninety - one lithologic traps have be discriminat-ed, which effectively guide the exploration.更多还原
