摘　　要：辽河盆地38-32块大凌河油层经过多年的蒸汽吞吐开发,开发矛盾突出,亟需转换开发方式。通过岩心刻度测井,建立单井隔夹层的电性和物性识别标准。利用不同厚度隔夹层在地震波形响应特征上的差异,建立厚度大于3m隔夹层的地震识别方法,确定隔夹层井间发育特征。研究发现,38-32块隔夹层主要分布在区块边部,且沿河道方向隔夹层发育较差。井震结合,精细刻画了38-32块大凌河油层隔夹层分布特征,为区块转换开发方式提供了技术参数,对剩余油分布研究及开发方案的编制有着重要意义。Over years of steam huff and puff operations,obvious contradictions have occurred in the development of Dalinghe reservoir in Block 38-32,the Liaohe Basin. Accordingly,the development mode should be transformed. Through core scale logging,the criteria are established to identify electrical and physical properties of the intercalations in individual well. Depending on the seismic waveform response features of intercalations with different thicknesses,the seismic identification method is proposed for intercalations with thickness more than 3m,in order to determine the characteristics of inter-well intercalations. The research results show that,in Block 38-32,the intercalations mainly distribute at the edges and present poor development along river channels.Based on the well-seismic data,the distribution of intercalations in Dalinghe reservoir of Block 38-32 is depicted in detail,which can provide technical parameters for transformation of development mode and also be significant for studying the remaining oil distribution and preparing the development plan.
