为揭露扎鲁特盆地构造格架和识别二叠纪林西组地层分布特征,笔者在扎鲁特盆地进行重力、磁力、大地电磁综合地球物理调查。在2012年,采集了5条北西向大地电磁剖面。经过数据处理、分析后,反演后电阻率断面揭露了断层带和林西组分布特征。扎鲁特盆地西部边界被确定。发现了两个低阻带,推测它们可能是与页岩气有关的泥岩。这些工作将为扎鲁特盆地页岩气潜力评价提供依据。
In order to reveal the tectonic framework of Zhalut Basin and identify the distribution characteristics of strata in the Permian Linxi Formation, the author conducted a comprehensive geophysical survey of gravity, magnetism and geomagnetic in Zhalut Basin. In 2012, five North-west trending electromagnetic profiles were collected. After data processing and analysis, the resistivity profile after inversion reveals the distribution characteristics of the fault zone and the Linxi Formation. The western boundary of the Zarut Basin was identified. Two low-resistivity bands were discovered, suggesting that they may be shale-related shales. These works will provide the basis for the evaluation of shale gas potential in Zhalut Basin.
