在欧拉反褶积方法的研究中,过去常直接用原始位场异常值及其导数进行反演,由于数据的局限性,有时导致反演结果的发散.为改善反演结果的收敛性,本文中采用了垂直导数、水平导数及解析信号作为源数据进行欧拉反演.(1)推导了重、磁异常不同数据类型的欧拉方程;(2)找出了重、磁异常不同数据类型的欧拉方程之间的联系和差异;(3)通过模型计算比较,证明用导数或解析信号进行欧拉反演计算,可改善反演效果,提高反演结果的收敛性.
In the research of the Euler deconvolution method,it commonly uses potential filed anomalies and their derivatives in calculation in the past. Due to data limitation, sometimes it leads to the divergence of inverted result. To improve the astringency of Euler inverted result, we use vertical derivative, horizontal derivative and the analytic signals to solve Euler's equation. We have deduced Euler's equation of gravity and magnetic anomalies for different data types. We find out the relationship and difference of gravity and magnetic anomalies for different data types. Via calculation of the model, we prove that use derivatives or analysis signal can heused to improve, the astringency of result.
