| 摘 要： | 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。

| Abstract: | In order to disclose tectonic framework of the Jarud Basin and identify Permian Linxi Formation distribution,an integrative geophysical survey comprising magnetotelluric,gravity,and magnetic methods was performed in the fault-bounded Jarud Basin.Magnetotelluric data were collected from five NW profiles in 2012.After data processing and analyzing,inverted electric resistivity sections disclosed fault zones and Linxi Formation characteristics.The western boundary of the Jarud Basin was determined,and two low-resistivity belts were discovered,which may be the mudstone associated with the shale gas.The work will provide the basis for assessment of potential shale gas in the Jarud Basin. |
