大地电磁激电效应油气检测试验
Keywords: 大地电磁测深,柯尔—柯尔模型,激电效应,油气检测
Abstract:
?柴达木盆地a气田主要产气层段因与其上、下段电性差异大,呈现明显的高电阻率特征,应用大地电磁测深方法能够反映这种电性变化。但影响地层电阻率升高的因素较多,通常应用大地电磁测深也不能准确确定引起高电阻率异常的原因。为此,本文开展大地电磁激电效应试验。结合试验区的地质目标,在电磁法中引入频谱激电法中的柯尔—柯尔模型模拟大地激发极化特性,提取激发极化信息。试验结果表明,气田区呈现高电阻率、高极化异常模式,由此可利用极化异常对高电阻率异常的含油气性进行检测评价,有可能指示油气的存在。
