本文讨论了电磁频率测深转换相位法的主要原理,并在PC1500机上实现,它可以弥补不能实测相位的不足,因而有较强的实用性。计算结果表明:转换相位曲线与理论相位曲线形态一致．并且有分层明显、反映大深度基底能力强的特点,它同实测相位曲线一样,能够真实地反映地电信息和断面特征。在此研究基础上,提出了利用相位和振幅进行频率测深综合解释的解释方法。使用该方法对黑龙江绥滨测区频率测深的解释结果与钻孔和资料相比效果较为满意。
This paper discusses the principle of electromagnetic frequency sounding conversion phase method, and implemented in the PC1500 machine, it can make up for the lack of phase can not be measured, and therefore has strong practicality. The calculation results show that the phase transition curve is consistent with the theoretical phase curve. It also has the characteristic of being stratified obviously and reflecting the capability of large deep basement. Like the measured phase curve, it can truly reflect the geoelectric information and cross-section features. On the basis of this study, an explanation of the comprehensive interpretation of frequency sounding using phase and amplitude is proposed. Using this method, the interpretation result of frequency sounding of Suibin survey area in Heilongjiang Province is more satisfactory than that of drilling and data.
