低幅度构造CARTOSAT-1卫星遥感勘探应用探索——以柴达木盆地三湖地区天然气勘探为例
|
摘要
柴达木盆地三湖地区,湖泊、湖沼、盐碱发育,受地质构造条件控制,仅发育低幅度构造。对于低幅度构造目标的勘探,近年来地震勘探效果不佳。本文利用卫星遥感技术,通过对已知气田遥感特征、成藏条件和分布规律的对比分析,认为三湖地区已知气田或含气构造的浅表构造特征与地下低幅度构造的分布具有良好的对应性或继承性。由此,探索和研究了利用印度CARTOSAT-1卫星信息,提取和解译识别正地形,结合相关油气地质资料,综合分析发现低幅度勘探目标的方法,可推广应用于地势平坦、地震勘探效果不佳的类似地区。
The topography is even in the Three Lake area of the Qaidam Basin.Many lakes,swamps and salinas are distributed in the area.The geology is low range structure controlled by the natural geology structure condition.The effect of exploration aimed to the low range structure is not fine.The authors make use of the remote sensing technique to find out the correspondence and inheritance between the surface structure character and the subterranean low range structure,accumulation conditions and distribution law of the existing gas filed.Therefore the gas-bearing structure can be found.The set of disposal,pick-up and interpretation techniques is drawn out.The basic conclusion is that the method is very useful in oil and gas exploration in the low range structure with the CARTOSAT-1 remote sensing data based on the correlative oil and gas geological data.
