By analyzing the distribution of global oil and gas fields and the reasons why some oil and gas fields are not in production, the distribution characteristics of oil and gas remaining recoverable reserves and their year-on-year changes, the distribution characteristics of oil and gas production and their year-on-year changes, and the development potential of oil and gas to be tapped in 2021, this paper sorts out systematically the current status and characteristics of global oil and gas development, summaries the major trends of global oil and gas development, puts forward enlightenment for international oil and gas cooperation. In 2021, oil and gas fields were widely distributed, the number of non-producing oil and gas fields was large;the whole oil and gas remaining recoverable reserves declined slightly, unconventional oil and gas remaining recoverable reserves dropped significantly;the overall oil and gas production continuously increased, the outputs of key resource-host countries kept year-on-year growth;undeveloped oilfields had abundant reserves and great development potential. Combined with global oil and gas geopolitics, oil and gas industry development trends, oil and gas investment intensity, and the tracking and judgment of hotspot fields, the major trends of global oil and gas development in 2021 are summarized. On this basis, the four aspects of enlightenment and suggestions for international oil and gas cooperation and development strategies are put forward: attach great importance to the obligation of marine abandonment to ensure high-quality and long-term benefit development of offshore oil and gas;adhere to the principle of not going to dangerous and chaotic places, strengthen the concentration of oil and gas assets, and establish multi stable supply bases;based on the multi-scenario demand of natural gas, realize the transformation from integrated collaboration to full oil and gas industry chain development;increase the acquisition of high-qualit

This paper presents an analysis of four aspects, including the distribution and production of global oil and gas fields, the distribution and changes of remaining recoverable reserves, the differences in oil and gas production between regions/countries, and the development potentials of oil and gas fields unproduced and to be produced in 2023. On this basis, the situation and characteristics of global oil and gas development are expounded, and the trend of global oil and gas development is summarized. In 2023, upstream oil and gas production landscape is expanding, and the number of oil and gas fields in production is increasing significantly; oil and gas recoverable reserves increased year-on-year, driven by significant contributions from new discoveries and reserve re-estimates; the overall oil and gas production grew continuously, with notable contributions from new projects coming online and capacity expansion efforts; and the oil and gas fields unproduced or to be produced, especially large onshore conventional oil fields and economically challenging offshore gas fields, host abundant recoverable reserves. From the perspectives of reshaping oil and gas production areas due to the pandemic and Russia-Ukraine conflicts, geopolitical crises, capital expenditure structures in petroleum exploration and development, and the proactive layout of oil and gas associated resources, the trend of global oil and gas development in 2023 was analyzed systematically. The enlightenment and suggestions in four aspects are proposed for Chinese oil companies to focus on core businesses and clarify development strategies in the post-pandemic era and the context of energy transition: The global oil and gas landscape is undergoing profound adjustments, and it is essential to grasp development trends, especially in core businesses; upstream business exhibits a strong potential, and emerging fields are considered as new growth poles; the prospects for tight/shale oil and gas are promisi

美国是现代石油工业奠基者,推动世界油气发展,通过石油公司的全球布局,牢牢掌控北美“后院”,虎视眈眈南美“前院”。二战后,美国历经70年的探索布局,实现了能源独立,开启了能源霸权。文章在回顾美国石油工业发展史基础上,分析了我国跨国油气勘探开发在保障国家能源安全方面的作用:(1)通过国际市场运作海外份额油气回国保供,担负起了利用“两个市场”“两种资源”的责任;(2)开展油气合作,夯实我国油气战略通道沿线的上游资源基础,成为支撑国家“一带一路”倡议的主力军,有效降低了我国油气综合对外依存度。在百年变局和世纪疫情大背景下,文章针对全球地缘政治复杂多变、“双碳”目标下的能源转型、中美全面博弈等诸多挑战,提出了相关启示与建议,为中国国有石油公司“走出去”、进一步分享全球油气资源、保障国家能源安全提供参考。

地震资料人工解释断层往往具不确定性。随着计算机和人工智能的发展,深度学习技术越来越多地应用于地球物理领域,多种基于卷积神经网络的算法也广泛地应用于断层识别。为此,结合三维U-Net和深度残差网络,引入多层深度监督的机制,构建了一种基于三维深度监督网络的断层检测方法。残差模块的引入能够简化网络的学习目标,降低训练难度,而多层的深度监督能够为网络提供更多的反馈,减轻训练过程中潜在的梯度消失,使解码器子网络能够学习到不同尺度的断层语义信息,可进一步提高断层识别的准确性。理论模型测试和实际地震资料的应用表明,该方法可以有效识别断层位置;与常规U-Net网络相比,减少了小断层的漏识别和错误识别;识别的大断层连续性好,断层细节更丰富,明显提高了断层识别的准确性。
