随着油气勘探的不断深入，惠民凹陷南坡中生界成为目前重要的勘探层系。本文以岩性组合、敏感测井曲线及地震资料为基础对中生界各组段进行了划分与对比，落实了中生界各组段的沉积特征及地层的分布规律。分析了中生界内幕构造的特征，探讨了中生界构造格局的形成演化及其对中生界残留地层分布的控制。研究结果表明，北西、北东两期构造的不均衡叠加控制了中生界现今构造格局，中生界残余地层总体表现为沟厚梁薄，有利的储层主要沿北西向断层下降盘分布。在以上地质特征研究的基础上，从油源断层、油气输导层及圈闭刻画三方面对油气勘探思路进行了探讨，预测了有利的勘探目标区。%With the in‐depth development of hydrocarbon exploration ,the Mesozoic has been an important exploration object .Based on the Lithology combination ,Sensitivity logging curve and 3D seismic ,Mesozoic formation segment is divided and correlated ,the sedimentary characteristics and strata distribution are also confirmed .Mesozoic internal structural characteristics is analyzed ,the formation and evolution of tectonic pattern and the control of relic strata distribution by that are discussed .The results show that the NW and NE structural imbalance superposition controls the present tectonic pattern of Mesozoic ,the relict strata thickness is thick at the syncline and is thin at the anticline .The favorable reservoir is mainly along the downthrown side of NW faults . Based on above research ,hydrocarbon exploration strategy is discussed from oil source fault ,oil transporting layer and trap characterization ,the favorable exploration target areas are predicted .
