摘要:
多道瞬变电磁法(MTEM)具有深度大且探测精度高的特点,是目前电磁法领域研究热点之一。为推进多道瞬变电磁法深部探测系统的研发,对多道瞬变电磁法的技术特点及地球物理机制进行了分析。首先,对多道瞬变电磁法的关键技术进行总结,其特点包括:采用大功率接地源形式;编码发射;多道观测;类地震资料处理。然后,指出多道瞬变电磁法的地球物理实质:多道瞬变电磁法属于近源测深,即通过改变偏移距达到测深目的;接收信号包括系统响应和大地脉冲响应(即含有一次场与二次场的混合场)信号,采用反卷积方法获取大地脉冲响应。最后,针对中国复杂环境下的深部探测,对现有的多道瞬变电磁法提出改进思路:①把二维观测系统改进成三维观测系统,即三维数据采集系统,使其应用性更强且更方便,探测深度大,精度高;②把常规一维拟地震资料简单处理改进成三维拟地震成像解释;③从油气勘探领域拓展到复杂的深部矿产资源领域。
