摘　　要：为实现成熟探区边部的有效开发,以松辽盆地高12区块为对象,利用RGB属性融合技术定量刻画了骨架砂体平面几何形态,并以沉积模式指导,测井识别进一步落实了非骨架砂体展布。研究结果表明:高12区块划分为1个长期旋回层序、2个中期旋回和12个短期旋回,为总体水进的浅水三角洲前缘亚相沉积;发育5种沉积微相,水下分流河道呈低弯度顺直条带状沿北西-南东向展布,宽厚比集中在52~67,席状砂大面积片状发育,水下分流间湾呈豆状零星分散,偶见天然提、河口坝。沉积微相绘制方法,实现了稀井网区薄窄砂体精细刻画目的。This paper is an attempt to realize the effective development of the edge of the mature exploration area.The study building on the G12 block of songliao basin involves quantitatively characterizing the plane geometry of the skeleton sand body by optimizing seismic slice by well control,determining the boundary of sand and mud,and using RGB attribute fusion technology;and thereby realizing the distribution of the non-skeleton sand bodies by logging facies identification under the guidance of deposition mode.The results show that the G12 block is divided into 1 long-term cycle sequence,2 medium-term cycles,and 12 short-term cycles,assuming the sedimentary characteristics of shallow water delta front subfacies with overall transgression;it features five types of developed sedimentary microfacies,as characterized by the distribution of the underwater distributary channels along the NW-SE direction in a straight strip with low curvature;the concentration of width thickness ratio in 52-67;the large-area and flaky development of sheet sand;the bean-shaped scatter of the underwater distributary Bay;and the occasional occurrence of natural levee and mouth bar.The sedimentary microfacies mapping method enables the fine delineation of thin and narrow sand body in thin well pattern area.
