摘　　要：辽河滩海地区古生界具有岩性类型丰富,储层类型多样的特征,勘探潜力较大,是重点的勘探领域之一。针对岩心薄片鉴定的结果,以测井识别为目的,将岩性重新划分为七种类型,利用交会图组合识别方法,建立地区古生界典型岩性的测井识别标准。在岩性识别的基础上,结合储集空间类型分析,确定了研究区发育三类储层类型,分别为裂缝-孔洞型、裂缝-孔隙型、裂缝型储层。不同储层类型对应不同测井响应特征,整体表现为高阻背景下的低阻,三孔隙度增大的特征。There are rich lithology types and diverse reservoir types in Paleozoic of Liaohe Offshore,which has great exploration potential and is one of the key exploration fields.According to the results of core thin section identification,the lithology is redivided into seven types for the purpose of log-ging identification.The logging identification standard of typical lithology of Paleozoic in the area is established by using the crossplot combination identification method.On the basis of lithology identi-fication,combined with the analysis of reservoir space types,three types of reservoir are determined in the study area,which include fracture-hole type,fracture-pore type and fracture type.Different reservoir types correspond to different logging response characteristics,which shows low resistivity under high resistivity background and enlargement of three porosity curves value.
