双源倾子响应特征分析
Analysis of response characteristics of double source tipper
摘要
Abstract
The controlled-source tipper electromagnetic method has been widely used in oil,gas and mineral exploration in recent years.The conventional tipper information obtained from single-source excitation has a singularity region,which leads to errors in the calculation of controlled-source tippers,limiting the application of the controlled-source tipper EM method to the entire measurement region.In contrast,double source measurements follow the principle of vector synthesis,which theoretically eliminates the measurement singularity region compared to single source measurements,and thus it is necessary to carry out the characterisation of tipper response for double source excitation.In this thesis,the integral equation method is used to realize the three-dimensional forward simulation of the electromagnetic method for controllable source tippers,and the vector superposition principle is used to obtain the horizontal and vertical magnetic field responses of multi-field source excitations,which in turn enables the calculation of double source tippers.The characteristics of tipper response of double low resistance anomalies,double high resistance anomalies and combined high and low resistance anomalies models are analysed on the basis of verifying the correctness of the procedure.The numerical simulation results show that:the double source tipper information can effectively reflect the location of the anomalies;the tipper amplitude,real and imaginary parts of the low-resistance anomalies present a high value response on the left side and a low value response on the right side;the high-resistance anomalies show the opposite characteristics and the amplitude,real and imaginary parts of the Tzx(the component of the controlled-source tipper in the X direction)are more clearly portrayed for the anomalies.This is an important guide for the application of the double source tipper EM method in practice.关键词
