Optimization Of Euler's Deconvolution And Its Application In Target Positioning

Euler's deconvolution method is based on gravity and magnetic anomaly and its derivative in different directions.Under a given structural index,the position coordinates of the field source are automatically estimated.The structural index is a parameter describing the type of geological body.In actual data interpretation,Due to the complexity of the underground geologic bodies and the anomalous mutual superposition between the geological bodies,the structural index is difficult to estimate accurately and is not a single one.This paper compares the effect of constructing exponential error on the accuracy of inversion results through theoretical model experiments and proposes an optimized Euler deconvolution method.First,it extracts the target body anomaly through the spectral characteristics of the data,removes the background anomaly,and thus locates the position parameters and structure.The exponent is also solved as an unknown,and based on the distribution characteristics of the data and results,the screening criteria for the results are formulated.Through the tests of simple models and complex models,this method can effectively and accurately obtain the position and geological body type information of geological bodies.Gravity and magnetic exploration technology is gradually turning to multidimensional and multi-parameter aviation gravity and magnetic gradient measurement.It can provide the characteristics of geological bodies in different directions,effectively improve the horizontal resolution of geological bodies,and comprehensively utilize abundant data information to constrain each other.Obtaining a more accurate distribution of geological bodies is a hot topic of research today.Gradient Euler's deconvolution method uses the combination of gradient data to automatically calculate the position of a geological body.It also does not require any prior information.The gradient Euler deconvolution method uses the Euler equations to obtain the derivative in three directions,combines the derived equations into a matrix form,and solves the problem using the least squares method.The gradient information in different directions is integrated to obtain the underground information.Abnormal body position parameters and structural index.This paper compares and optimizes the application effects of the Euler deconvolution method and the gradient Euler deconvolution method,and proposes different solutions to the gradient Euler deconvolution method,and applies the good method to unexploded objects in Shanghai Jinshan area.The interpretation of magnetic anomalies obtained the position coordinates and structural index of unexploded objects.Aeronautical measurement provides multi-dimensional gravity and magnetic data with different height combinations.Constraint inversion of different height data can effectively improve the accuracy and stability of the results.Theoretically analyzes the way in which multidimensional data is combined with Euler's inversion,and tests the effect of multidimensional data acquisition methods on the accuracy of inversion results.It has important practical value and guiding significance for the exploration of actual geological resources.
