CNOOC(600938) 科技日报·2025-04-02 05:30Core Viewpoint - China National Offshore Oil Corporation (CNOOC) has successfully developed a groundbreaking deep-sea seismic data imaging processing technology, enhancing the understanding of underwater geological structures at depths of 3000 meters, thereby supporting deep-sea exploration and development efforts in China [1][10]. Group 1: Technology Development - The research team led by Liu Jinpeng completed the processing of 2600 square kilometers of three-dimensional seismic data in the Pearl River Mouth Basin, marking a significant advancement in domestic deep-sea exploration technology [1][10]. - The team faced challenges in noise reduction from complex diffraction multiple waves, which were initially not effectively addressed by traditional methods [2][3]. - By integrating artificial intelligence with traditional techniques, the team developed a novel technology for attenuating residual diffraction multiple waves, improving the clarity of effective signals by 30% [3][6]. Group 2: Data Precision Enhancement - The team encountered difficulties in enhancing data precision due to the limited penetration of seismic waves, which often resulted in the loss of critical geological details [5][6]. - They innovated a multi-dimensional reconstruction theory and an intelligent frequency band fusion algorithm, which improved the seismic wave identification capability from 50 meters to 25 meters, increasing data resolution by 60% [6][7]. Group 3: Modeling and Interpretation - The lack of drilling data posed a significant challenge for building accurate geological models, leading the team to explore extensive literature and consult industry experts [8][9]. - Through deep data analysis, the team successfully constructed a high-precision velocity model, which allowed for better identification of geological structures and potential oil and gas reservoirs [9][10]. - This integrated modeling and processing solution has opened new avenues for deep-sea oil and gas exploration in China, potentially revealing previously inaccessible resources [9][10].
