As a key component of remote-sensing technology, satellite gravity observation offers extensive coverage and high accuracy, effectively compensating for the shortcomings terrestrial measurements. Three-dimensional data inversion can predict physical property spatial distribution geological formations beneath surface by analyzing data. In this paper, heat source position within Gonghe Basin’s geothermal system is identified through analysis data, constrained deep-learning method proposed....
The 3D inversion algorithm for gravity data based on a smooth model constraint has been proven to yield reasonable density distribution. However, as the amount of observed and parameters increases, experiences issues with high memory consumption prolonged computation time. Therefore, corresponding problem in interpreting lies developing fast algorithm. conventional algorithm, regularization theory, requires introduction weighting function large matrix, involves storage operation matrix...
Three-dimensional inversion of gravity and magnetic data can determine the geometric location anomalous subsurface bodies quantitatively calculate size spatial distribution target body's physical parameters, providing a foundation for subsequent geological interpretation. The Tikhonov regularization method typically controls model space in processing to reduce non-uniqueness problems. However, various forms change weighting coefficient yield generally different results, depth resolution...
This paper presents a fast focusing inversion algorithm of magnetic data based on the conjugate gradient method, which can be used to describe underground target geologic body efficiently and clearly. The proposed method realizes an effect similar matrix compression by changing computation order, calculating inner product vectors equivalent expansion expressions. Model tests show that this strategy successfully reduces time single iteration so three-dimensional is realized under certain...
