The studio continues to unleash its innovative energy, and the Geophysical Exploration Institute has once again achieved six new technological innovation results.

In recent years, the science and technology innovation studios established by the Institute of Geophysical Exploration have served as powerful engines, continuously injecting innovative momentum into the institute’s development. Thanks to the tireless efforts of the studio members, the Institute of Geophysical Exploration has recently achieved another six groundbreaking scientific and technological innovations.

The achievements cover a wide range of technical methods, including the wide-field electromagnetic method and seismic exploration, and involve multiple aspects such as optimization of processing and interpretation techniques—from the development of data-processing software systems to the exploration of innovative application solutions. These include the authorization of an invention patent titled “A Forward Modeling Electromagnetic Data Visualization Method Based on Normalization Functions,” as well as three software copyrights for “A 3D Electromagnetic Slicing and Well Trajectory Coordinate Transformation System,” “A Fine-Grained Processing and Inversion System for Multi-Attribute Polarizability of Reservoirs Using the Wide-Field Electromagnetic Method,” and “An Integrated Software for Fracture Monitoring Data Analysis in the Wide-Field Electromagnetic Method.” Meanwhile, the academic papers “Electrical Structure Identification of Deep Shale Gas Reservoir in Complex Structural Area using Wide Field Electromagnetic Method” and “Research on the Application of the Wide-Field Electromagnetic Method for Detecting High-Relief Structures in Deep Shale Gas Reservoirs in the Western Chongqing Block” have been published, respectively, in the international academic journal APPLIED GEOPHYSICS (SCI indexed) and the proceedings of the 34th National Natural Gas Academic Annual Conference (2024) (EI indexed).

Achievements of the Gu Zhiwen Talent and Innovation Studio

The invention patent, “Forward Modeling Electromagnetic Data Visualization Method Based on Normalization Functions,” primarily focuses on processing inversion data using first-order and second-order derivatives to calculate rate of change, thereby transforming electrical parameters into results that resemble seismic imaging.

The “Integrated Software for Data Analysis of Wide-Field Electromagnetic Fracturing Monitoring” is an analytical and mapping software designed for evaluating the results of wide-field electromagnetic fracturing monitoring. This software primarily offers a range of practical functions, including analysis of the affected area, maximum affected length, affected width, fluid volume analysis, fluid usage intensity analysis, re-fracturing area analysis, and cluster perforation utilization degree analysis. These features significantly meet the engineering needs in the field of fracturing monitoring, greatly enhancing work efficiency and saving time and effort.

The academic paper “Electrical Structure Identification of Deep Shale Gas Reservoir in Complex Structural Area Using Wide Field Electromagnetic Method” (《Based on Wide-Field Electromagnetic Method: A Study on Electrical Structure Identification of Deep Shale Gas Reservoirs in Complex Structural Areas》) thoroughly discusses how the wide-field electromagnetic method, with its high precision and great depth capability, can effectively characterize the electrical properties of thin, low-resistivity layers in deep formations within complex structural areas. The study also develops a new, low-cost evaluation technique for shale gas target formations based on the wide-field electromagnetic method.

Liu Jinhui Science and Technology Innovation Studio’s Achievements

The “Wide-Field Electromagnetic Method Reservoir Polarizability Multi-Attribute Fine Processing Inversion System” is a domestically pioneering development—a self-reliant technological innovation for inverting reservoir polarizability using the wide-field electromagnetic method. It has already been applied to the maturity assessment of the Changning shale gas reservoir and holds great potential for widespread application in the detection of shale gas content.

The academic paper titled “Research on the Application of Wide-Field Electromagnetic Method for Detecting High-Dip Structures in Deep Shale Gas Reservoirs in the Western Chongqing Area” explores the use of the new wide-field electromagnetic method to conduct structural exploration in high-dip structural zones. The study has achieved significant technological breakthroughs and yielded novel findings, clearly delineating the structural features in areas with complex high-dip structures and regions where seismic data imaging is less reliable. It accurately identifies the locations of fault traces and fault intersections, providing effective support for the deployment of development plans and offering a new solution for fault detection in high-dip structural zones.

Achievements of Wang Anping Talent Innovation Studio

The software copyright “3D Electromagnetic Method Slice and Well Trajectory Coordinate Transformation System” can convert 3D volumetric data into 2D planar data and project known information, such as well trajectories, onto the transformed 2D plane. This facilitates quantitative interpretation and eliminates errors that might arise from manual coordinate transformations, significantly enhancing the efficiency of interpreting 3D electromagnetic survey results.

The achievement of the six outcomes mentioned above fully demonstrates the Institute of Geophysical Exploration’s profound strength and innovative capability in the field of geophysical exploration technology. Looking ahead, the Institute will continue to focus on innovation-driven development, concentrate on fostering new forms of productive forces, and fully leverage the pivotal role of its science and technology innovation studios. We will further enhance the Sichuan Resource Geophysical Exploration brand, continuously break through technological barriers, courageously scale new heights in science and technology, increase investment in scientific and technological research and development, cultivate high-level research teams, and promote the emergence of more high-quality scientific and technological innovations. In this way, we will contribute even greater geophysical expertise and strength to the Group’s fulfillment of its primary responsibility as a technology-driven strategic mineral resource exploration and development entity, and to its participation in the new round of strategic actions aimed at achieving breakthroughs in mineral exploration.
