Geological Significance Of Radon Transformation Of Conventional Logging Curve

In this paper,Radon transformations of the logging curve Radon transform are used as the goal,and more Radon transformations in seismic data processing are introduced into the logging curve analysis.In order to realize the geological significance of Radon transform,the following work is done in this paper.Firstly,the principle of Radon transform method is summarized and the advantages,disadvantages and application of each Radon transform are analyzed.Secondly,a Radon transform program is written on the MATLAB platform to simulate single and multiple events in seismic exploration.The linear Radon transform and parabolic Radon transform are used to detect each model.The test shows that the program is stable and the parabolic Radon transform better separation of the events.Thirdly,the paper summarizes the application of Radon transform in seismic data processing and the theory of logging full-wave field.By analogy,Radon transform is introduced into the full-wave field data processing.Finally,the wave field separation and analysis of the full-wave wave field data of hard and soft strata are analyzed respectively,which reveals the geological significance of Radon transform of conventional logging data.Through the above research,it is shown that the Radon transform is a transformation along a specific path,and the data in the regular domain(such as the t-x domain)can be transformed into the Radon domain.The Radon transform has very good signal fidelity;the parabolic Radon transform is better to use the parabola as the integral path in the case of the hyperbolic events.The acoustic wave of the multi-channel data is similar to the seismic exploration.The full-wave logging data in the logging can be analyzed by Radon transform,and the Radon transform can be realized for the full-wave logging data.The Radon transform can be used to extract the longitudinal wave,transverse wave and the Stonyley wave,soft-ground full-wave logging data Radon transform can only extract the longitudinal wave and Stoneley waves.The separation of transverse waves can be used for rock mechanics analysis,and Stoneley waves can be used for reservoir permeability evaluation and fracture research.This further illustrates the geological significance of the conventional logging data Radon transformations.
