摘　　要：“复杂地表、复杂地下”双复杂地质条件,属于地震勘探中最具挑战性的工作之一,增加了山前带的地震勘探难度。准南山前带MJK地区在构造上位于第一排山,地表情况更复杂,构造变形剧烈,地震成像品质差,圈闭难以落实,油气勘探面临更大困难。针对该难题,本文开展二维地震正演模型验证,论证速度建模思路的可靠性。通过在研究区进行处理解释一体化运作,最终得到可靠性强、成像精度高、断裂特征明显的地震资料,提高了构造圈闭落实的可靠程度,为准南山前带油气勘探的突破打下良好基础。The seismic exploration in the mountain front zone is considered one of the most challenging tasks in seismic exploration due to the complex geological conditions of"complex surface and complex underground".The MJK area in the front of the Zhunan Mountain is structurally located in the first row of mountains,with more complex surface conditions,severe structural deformation,poor seismic imaging quality,difficulty in implementing traps,and greater difficulties in oil and gas exploration.In response to this challenge,a two-dimensional seismic forward modeling verification was carried out to demonstrate the reliability of the velocity modeling approach.Through integrated processing and interpretation operations in the research area,seismic data with strong reliability,high imaging accuracy,and obvious fault characteristics were ultimately obtained,which improved the reliability of structural traps and laid a good foundation for breakthroughs in oil and gas exploration in the quasi southern edge of the mountain front.
