摘　　要：从对临清东部中生界地层的岩性、古生物、测井及地震特征的总结和描述入手,归纳了地层垂向划分的判识标准,建立了中生界垂向地层格架。在此基础上又结合大的区域不整合面的地震响应,将中生界划分为2个构造层,通过钻井标定和对大量地震剖面的解释及横向上对单井的联井对比,确定了各构造层残留地层的展布特征,绘制了残留地层等厚图。Through the summing-up and description of lithology, palaeobiology, well logging and seismic characteristics, the paper concluded the discriminatory standard of vertical demarcation of stratum, and established the vertical layer framework of Mesozoic of Linqing. Based on this theory and also in combination with the seismic effects of large size regional unconformity surface, the Mesozoic deposition in this area can be divided into two structural layers. Through the calibration of well drilling, interpretation of large seismic cross sections and the lateral correlation of combining each well, distribution characteristics of remnant strata of every structural layer have been ascertained, and isograms of remnant strata have been drawn up.
