| 摘 要： | 建立了济阳坳陷下第三系高精度层序地层格架和层序体系域的构成模式。研究结果表明，受构造坡折带控制的层序低位域砂体，如下切水道充填、低位楔和低位扇砂体以及湖扩展体系域砂体，其成藏条件良好，最有利于形成隐蔽油气藏。受构造坡折带控制的隐蔽油气藏在地震剖面上反射特征明显，易于识别，可在地震剖面上预测这类油气藏。结合济阳坳陷隐蔽油气藏的勘探实例，讨论了隐蔽油气藏的勘探和预测方法。

| Abstract: | A model for the Lower Tertiary framework and sequence system tract of Jiyang subbasin was established with the high_resolution sequence stratigraphy.The study results show that the lowstand sand bodies such as incised channel filling,lowstand wedges and fans controlled by the structural slope_break zones are favorable for forming the subtle reservoirs.The subtle reservoirs controlled by the structural slope break zones with apparent seismic reflection characteristics are apt to be identified and forecasted on the seismic profiles.The methods for subtle reservoir exploration and forecast were discussed,taking a case study of Jiyang subbasin as an example. |
