摘　　要：基于野外采样分析,初步明确思茅坳陷主要烃源岩丰度特征,龙潭组的煤系地层与和平乡组下部的海相深色泥岩为坳陷最为重要的烃源岩层段。工区发育大水井组的颗粒灰岩与景星组的石英砂岩二套主要储层。通过对2012年4条二维地震测线的解释,共发现盐店、翁孔、那武及嘎胡四个主要构造圈闭,并在工区南缘的那武附近发现呈北东向展布的背斜群。综合多种成藏有利要素分析,思茅坳陷具有巨大的油气勘探潜力。Study indicates that most important source rock in the Simao depression was mainly composed of coal measures of the Upper Permian Longtan Formation and dark marine mudstone of the Middle Jurassic Hepingxiang Formation. The major reservoirs consist of the grain limestone of the Dashuijing Formation and quartzose sandstone of the Lower Cretaceous Jingxing Formation. Four structural traps as such as Yandian, Wengkong, Nawu and Gahu were discovered by 4 seismic lines in this region in 2012. The Simao depression has huge exploration potentiality for oil and gas.
