惠民凹陷大芦家地区沙二段构造复杂，目的层埋藏较深且受到火成岩的穿插，给地震波组连续性的识别及同相轴的追踪造成了一定的困难，加上研究区位于临邑大断层断棱区域，断层十分发育、地层变化快等特征，使得断块更为破碎，地震资料受到了更大的影响，精细解释工作愈加困难。研究立足井震结合，综合运用层位标定、相干分析、变速成图、断点组合等多项技术，实现了断块区构造的精细刻画，为构造地质模型的建立及油藏开发奠定了基础。
惠民凹陷大蘆傢地區沙二段構造複雜，目的層埋藏較深且受到火成巖的穿插，給地震波組連續性的識彆及同相軸的追蹤造成瞭一定的睏難，加上研究區位于臨邑大斷層斷稜區域，斷層十分髮育、地層變化快等特徵，使得斷塊更為破碎，地震資料受到瞭更大的影響，精細解釋工作愈加睏難。研究立足井震結閤，綜閤運用層位標定、相榦分析、變速成圖、斷點組閤等多項技術，實現瞭斷塊區構造的精細刻畫，為構造地質模型的建立及油藏開髮奠定瞭基礎。

Es2 lower section has complex structure in Dalujia area, Huimin sag. The target stratum is deep buried and interpenetrat-ed by igneous rock. Therefore, it is difficult to distinguish the continuity of seismic waves group and track the event. Besides, as the study area is located in Linyi major fault edge with developed faults and fast varied formation, the seismic data is greatly affected by complicated crack that brings great difficulties for the fine interpretation. Based on log and seismic data, the technologies like hori-zon calibration, coherence analysis, variable velocity mapping and break point combination are used to describe the feature of struc-ture. It lays a solid foundation for constructing geological model and reservoir development.
