“Double Harvest” Achieved | The Institute of Geophysical Exploration Has Recently Been Granted a New Invention Patent and Had an Article Accepted by an SCI Journal
After tireless efforts and in-depth exploration, the research team at the Institute of Geophysical Exploration has once again achieved a breakthrough in both technological innovation and academic research in geophysical exploration. They have successfully obtained an invention patent authorization for “A Method and Apparatus for Detecting Stratigraphic Discontinuities Based on Adaptive Higher-Order Maximum Entropy WVD.” Meanwhile, their academic paper titled “Study on Electrical Structure Identification of Deep Shale Gas Reservoir in Complex Structural Area Based on Wide-Field Electromagnetic Method,” submitted to the international academic journal Applied Geophysics (indexed by SCI), has also been accepted for publication.
Invention patent
The core of the invention patent “Method and Apparatus for Detecting Stratigraphic Discontinuities Based on Adaptive Higher-Order Maximum Entropy Wigner-Ville Distribution” lies in leveraging adaptive higher-order maximum entropy Wigner-Ville distribution (WVD) technology to achieve high-precision detection of stratigraphic discontinuities. The WVD is a quadratic time-frequency distribution with wide applications in signal processing fields such as fault detection. The maximum entropy technique can eliminate interference components inherent in the WVD while preserving its high resolution and high focusing capabilities. Moreover, the adaptive higher-order maximum entropy WVD technology can automatically determine the order of the distribution based on data-driven approaches, further enhancing its performance in detecting stratigraphic discontinuities and enabling more accurate identification of subsurface rock layer structural features and anomalous information.
Academic paper
The paper “Study on Electrical Structure Identification of Deep Shale Gas Reservoir in Complex Structural Area Based on Wide-Field Electromagnetic Method” delves into the issue of electrical structure identification for deep shale gas reservoirs in complex structural areas. The study employs the wide-field electromagnetic method and successfully addresses the challenges in identifying deep shale gas reservoirs in complex structural regions, providing new insights and methodologies for the exploration and development of shale gas resources.
The achievement of the two outcomes mentioned above fully demonstrates the Institute of Geophysical Exploration’s profound expertise and innovative capabilities in the field of geophysical exploration technology, while also injecting new vitality into the development of new-quality productive forces in the exploration of natural mineral resources.
In the future, on the path of scientific and technological innovation, the Institute of Geophysical Exploration will continue to play a leading role, forge ahead with determination, constantly push beyond our limits, courageously scale new heights in science and technology, intensify investment in scientific and technological research and development, cultivate high-caliber research teams, and promote the emergence of more high-quality scientific and technological innovations. We will contribute even more wisdom and strength to the exploration of natural mineral resources in Sichuan Province and across the country, making ever-greater and outstanding contributions.
