摘　　要：为了提高碎屑岩沉积微相图的制图精度，并增强其横向预测性，以满足岩性油气藏精细勘探的需要，在松辽盆地北部齐家地区，针对高台子油层，探索了井震结合大比例尺沉积微相制图方法。在精细地震层位解释与系统沉积地质学分析基础上，进行地震属性切片、区域沉积体系分布规律分析及单井沉积相解释工作；通过地质认识确定沉积微相类型，依据地震显示刻画砂体形态，编制沉积微相图初稿；最后进行单井沉积相校正，完成大比例尺沉积微相图。制图方法已用于指导勘探部署，并取得了较好的钻探效果，预测砂体均钻遇，且见多层油气显示。应用效果表明此种新的制图方法精细、实用，能有效推动岩性油气藏精细勘探，值得推广。In order to improve mapping accuracy of clastic rock sedimentary micro-facies and enhance lateral prediction so as to satisfy detailed exploration requirements of lithologic reservoirs, the mapping method of well-seismic combination with large-scale sedimentary micro-facies is ern Songliao Basin. On the basis of fine seismic horizon studied aiming at Gaotaizi Reservoir of Qijia area in northinterpretation and analysis on systematic sedimentary geology, seismic attribute slice, region sedimentary system ＇ s distribution rules and single well sedimentary facies interpretation are carried out. Then, types of sedimentary micro-facies are determined by understanding geology and its first draft of mapping is complied according to sandbody form shown by seismic. At last, single well sedimentary facies calibration and large-scale sedimentary micro-facies mapping are finished. This method has been used to guide exploration deployment and achieved better drilling results, with all predicted sandbody encoutered and several layers with oil and gas shows. Application of this method indicates that, this new mapping method is fine and practical which can improve lithologic reservoirs exploration.
