Research On 3D Radar Logging Data Processing And Interpretation Methods

With the rapid progress of science and technology and industrial revolution in the20 th century,oil has become an important source of energy for all industries,which not only profoundly affects our daily life,but also will remain an indispensable strategic energy source in the coming decades.In the field of oil exploration,the commonly used methods are logging technology and seismic exploration technology,but traditional geophysical logging has a small detection depth,while seismic exploration also has the problem of low resolution,while borehole radar happens to have a larger detection depth and higher resolution at the same time,so borehole radar is an oil exploration method with high potential.The 3D radar is a directional borehole radar,which is designed to compensate for the problem of omnidirectional reception of signals and the inability to distinguish the orientation of reflectors in an ordinary borehole radar.This paper focuses on the topic of 3D radar logging data processing and interpretation,and aims to verify the feasibility and application prospects of 3D radar logging.This paper focuses on the following four aspects: firstly,the study of the corresponding data processing and interpretation scheme according to the characteristics of 3D radar,the proposal of effective methods to denoise and enhance the 3D radar profiles,and the study of the interpolation algorithm for 3D radar logging.Next is the study of the supporting software,in which App Designer and MFC programming techniques are used to implement the software development and implement the above processing and interpretation scheme.Then also the analysis of directional detection effects of 3D radar and the study of anomalous characteristics of typical structures on 3D radar profiles were carried out by synthesizing the data through the finite difference method in the time domain.Finally,the practicality of the actual collected data is investigated by processing and interpreting them using the developed data processing and interpretation software.The two tools used in the software development,App Designer and MFC programming technology,have the advantages of simple operation and high software development efficiency,which can provide some reference and guidance for other researchers’ software development.The results of this paper show that the 3D radar is effective in directional detection,which not only confirms the feasibility of 3D radar logging technology,but also provides an important reference value for future researchers.
