摘　　要：本文利用测井约束反演技术对位于辽中凹陷北洼部位的LZ21-4构造带储盖层进行了预测。在东营组上段T3UA,T3UB,T3UC三组反射中解释了4套储盖组合,并分别对T3UB,T3UC反射层中发现的3个单砂体进行了分析评价。认为LZ21-4构造带的T3UC地层中的2砂体储集物性好,且盖层条件也好。在此构造以南的LZ21-1S构造上的T3UC地层中的2砂体也具备良好的油气储集条件。The paper uses log-constraint inversion technique to predict the reservoir and cap in LZ21-4 structural belt situated in the part of northern sub-sag of Liaozhong sag. The 4 sets of reservoir and cap combination are interpreted on three groups of reflections T^U_ 3A,T^U_ 3B and T^U_ 3C in upper Ed Formation. Analysis and evaluation of three single sand bodies discovered on T^U_ 3B and T^U_ 3C reflections are carried out respectively. It is considered that No.2 sand body on T^U_ 3C of LZ21-4 structural belt has good physical character of reservoir and cap condition. The No.2 sand body on T^U_ 3C of LZ21-1S structural belt situated in southern part of above structure has also good reservoir conditions.
