Core Insights - The project organized by the China Geological Survey Bureau's Oil and Gas Resource Investigation Center has successfully passed the results acceptance for the "National Shale Gas Key Investigation Area Strategic Mineral Investigation and Evaluation" project, establishing a geophysical comprehensive investigation technology system suitable for the southern strong transformation area [1][2] - Shale gas has become an important growth point for natural gas production in China, with significant resource potential identified in the southern Sichuan Basin and surrounding areas, although the evaluation of new layers and areas remains low [1][2] Group 1 - The project has identified 20 favorable areas for shale gas in regions such as western Hubei-eastern Chongqing, western Sichuan, and central Hunan [1] - A total of 750 square kilometers of geological surveys were completed, along with gas content testing, seismic collection, electromagnetic measurements, and sample analyses, leading to breakthroughs in mineral exploration and geological innovation [1][2] Group 2 - Significant discoveries include stable shale gas industrial flow of 4,234 cubic meters per day from the Yuwu 1 well in the eastern Chongqing area, high gas content shale from the Eojian 2 well in western Hubei, and a shale-gas-tight gas composite reservoir found in the Shixi 1 well in western Sichuan [2] - The project established targeted evaluation standards for shale gas in complex structural areas and systematically assessed the shale gas resource volume in 20 favorable areas [2]
奋斗在“向地球深部探能源”的路上
Core Insights - The lecture by Guo Xusheng highlighted the significance of deep earth exploration in China's oil and gas industry, emphasizing the historical journey and breakthroughs in this field [1][3][4] Group 1: Deep Earth Exploration - Deep earth refers to the solid earth beneath the shallow surface that is difficult for humans to access, with significant research and resource utilization value at various depths [2] - The exploration of deep earth is challenging due to hard rock, complex internal structures, and high temperatures that affect equipment stability [2] - China's geological resources include 1,257 million tons of oil and 212 trillion cubic meters of natural gas [2] Group 2: Historical Development - The history of China's petroleum industry is characterized by a continuous effort to explore deeper, starting from an initial oil production of 120,000 tons to achieving self-sufficiency with the discovery of Daqing Oilfield in 1959 [3] - The exploration strategy evolved to discover significant oil fields such as Shengli, Liaohe, and Zhongyuan, pushing exploration depths to 4,500 meters and beyond [3] Group 3: Breakthroughs in Marine Natural Gas Exploration - The discovery of the Puguang gas field marked a turning point in China's marine natural gas exploration, overcoming initial skepticism and setbacks through rigorous geological research [5][6] - The team led by Guo Xusheng innovated theories and techniques that facilitated the successful discovery of the first marine gas field in China [5][6] Group 4: Shale Gas Exploration - The shale gas revolution globally prompted a shift in focus towards this challenging resource, with initial efforts yielding limited success due to complex geological conditions in China [8][9] - Guo Xusheng's team emphasized the need for independent innovation in shale gas exploration, leading to significant breakthroughs in the Fuling shale gas field [9][10] - The successful development of Fuling shale gas positioned China as the second country after North America to achieve commercial shale gas production [9][10]
