摘　　要：位于川东华蓥山推覆褶皱带前缘的南门场构造是川东地区主要含气构造之一。从南门场构造的地震剖面分析入手,可建立与实际数据相吻合的断层相关褶皱模型,将构造解释的多解性限制在合理的范围内。分析表明南门场构造存在三大断裂体系,其叠加组合形成了现今南门场复杂构造样式。合理的构造建模促使我们对南门场构造演化过程、多期构造叠加以及油气运移与分布规律等诸多因素进行重新思考。Nan Menchang structure, located in the front of the nappe--fold zone of Hua Ying Mountain, is among the major gas--containing formations in the east of Si Chuan Province. Based on the seismic profile of the structure, this paper suggests building up a fold model of the fault in accordance with the data acquired to narrow down the ambiguity of the structural interpretations. According to the analysis, Nan Menchang Formation consists of 3 major fracture systems whose overlapping constitutes the complex patterns of today. A well--built model can offer a new glimpse on the structural evolution, tectonic superimposing through multi--episodes and the migration and distrihution patterns of oil gas in Nan Menchang Formation.
