摘要
本文主要探讨了与压实褶皱有关的一类隐蔽油气藏的ＴＭ图像解译原理。根据压实褶皱的成因机制，对其盖层应力分布状况及其在后期构造运动中的受力变动情况进行了分析，提出与压实褶皱同时伴生的还有一系列特殊的裂隙型式，它们不仅为油气的储集提供了空间，而且在空间上还组成了特殊的组合型式（图像上呈现一定的图案），它们经过后期的风化剥蚀后可呈现出典型地貌特征。利用ＴＭ图像具有多波段、适中分辨率的优势可以在图像上对这些特殊的裂隙型式进行识别，从而可直接在图像上解译出埋丘、礁体、碎屑灰岩体、较纯的砂岩体、盐丘等形式的隐蔽油气构造。为进行油气勘探的靶区预测提供了一种更为迅速经济的手段。
The Interpretation principles of the remote Sensing image of a Subtle type of oil gas reservoir relevant to Compaction folds have been discussed in this paper. According to the formation mechanism of a Compaction fold, the state of stress distribution in its overburden, generated by Compacting, and the structural change affected by the force of the tectonic movement soon afterwards are analysed. This paper proposes that a series of particular fractures may appear, accompanying the formation of a Compaction fold. These frac- tures not only provide room for the storage of oil and gas but also form distinctive fracture patterns. When the fractures are weathered and eroded, they may evolve typical geomorphic features. These features Can be recognized on the TM images, by utilizing the advantages of the multispectrum and high resolution of TM images. Therefore the features of a subtle type of oil-gas reservoirs, generated by buried hills. reef-mounds. elastic limestone bodies. pure sandstone bodies and salt domes, Can directly be interpreted on the TM images.
