摘　　要：应用沉积、测井和地震资料,分析曲流河废弃河道及点坝的测井和地震响应特征,探索性地开展了曲流河单砂体刻画;应用密闭取芯资料进行岩电交互分析,建立起侧积泥岩识别模式,并依据对子井公式计算出侧积泥岩产状。研究表明,侧积泥岩的倾角θ约为3.47°,倾向指向废弃河道的外法线方向,泥岩夹层纵向下延伸到砂体底部的2/3处。通过对点坝砂体进行含油饱和度测试,发现侧积泥岩上部为剩余油富集区。根据以上成果制订合理的挖潜技术对策,取得良好效果。By application of sedimentary,well logging and seismic data,we analyze the logging and seismic response characteristics of abandoned channel and point bar in meandering river,and study on the property single sand body description in meandering river;We study the analysis rock electrical interaction with sealed coring data,build up laterally accreted mudstone recognition model,and on the basis of pairs well formula we calculate lateral accretion mudstone occurrence.Research shows that the slope angle of lateral mudstone is about3.47 °,the tendency is point to the outer normal of abandoned channel,mudstone interlayer longitudinal extension to 2 /3 at the bottom of sand body.By means of oil saturation test of the point bar sand body,we have found the top of lateral mudstone is still in enrichment of remaining oil.According to the above results we formulate reasonable measures of potential tapping technology and have achieved good results.
