Northeast Asia regional energy infrastructure proposals

Economic growth in the countries of Northeast Asia has spurred a massive increase in the need for energy, especially oil, gas, coal, and electricity. Although the region, taken as a whole, possesses financial, technical, labor, and natural resources sufficient to address much of the region's needs now and into the future, no one country has all of those attributes. As a result, over the past two decades, there has been significant interest in regional proposals that would allow sharing of resources, including infrastructure to develop and transport energy resources from the Russian Far East to South Korea, China, and Japan, and cooperation on energy-efficiency, renewable energy, and the nuclear fuel cycle as well. In this article we review some of these proposals, identify some of the factors that could contribute to the success or failure of infrastructure proposals, and explore some of the implications and ramifications of energy cooperation activities for energy security in the region.     

Indicators of security of natural gas supply in Asia

Natural gas has become an increasingly valuable resource and a global commodity. The demand for it has significantly increased. Japan, Korea and Taiwan heavily rely on liquefied natural gas (LNG) imports for their gas supplies from Malaysia, Brunei, Indonesia, Australia and the Middle East. On the other hand, countries like Thailand and Singapore import gas via trans-border pipelines. Gas supply interruptions, volatile gas prices, transportation and distribution bottlenecks, and a growing reliance on imports over longer distances have renewed interest on gas security in Asia. This paper examines the relative vulnerability to natural gas supply disruptions of seven gas-importing countries in Asia for year 2008. Based on four indicators of security of gas supply, a composite gas supply security index is estimated as an overall indication of gas vulnerability for our sample countries. The results demonstrate that there are differences in the values of the overall indicator of gas vulnerability among countries and the assessment is useful in developing an effective strategy of natural gas supply security in countries in the Asian region.     

东北亚天然气资源及其发展趋势

东北亚地区天然气资源丰富,具有远景资源量约70×10¹²m³.这里盆地类型众多,是世界上以古克拉通继承性盆地和晚期岛孤相关盆地为主的新含气区域.中国的华北、塔里木、扬子地区和俄国的西伯利亚属于古老克拉通;上扬斯克坳陷和库车坳陷则属于前陆盆地或克拉通边缘坳陷;东北萨哈林和东海为弧后盆地.天然气资源主要分布在克拉通及其边缘坳陷或前陆盆地中,约占资源潜力的0%.其次为与中新生代岛弧有关的位于现今大陆架的第三系盆地,资源潜力约占10%以上.目前东北亚天然气开发还处在比较低的水平,但它将是世界新的重要天然气资源地,该地区本身的天然气需求量也有强劲增长趋势.

北方型含油气域———纪念翁文波《世界油田的分布规律》发表50周年

北方型含油气域大致相当于翁文波当年建立的北方体系,此外还包括翁文波的太平洋系的北部。北方型含油气域又可分为亚洲、欧洲和北美3 个含油气域。3个含油气域中,各有一个面积较大的陆核,从东到西为阿纳巴尔、波罗的和加拿大。在陆核外围环绕着古生界带、中生界带和新生界带;这种环带形态主要呈半环形,并且各带之间重合不多,但在北美落基山西麓有较大面积的重合。在各含油气域的含油气盆地中,含油气岩层比较单一;盆地类型有内克拉通、前陆及褶皱带、活动大陆边缘、离散大陆边缘和内裂谷。在沉积速率分析曲线上,往往是古生代、中生代和新生代呈单峰状态。在油气田（藏）形成过程中,罕见油气再次运移现象,即罕见复式石油系统。     

基于夜光遥感的东南亚国家经济发展时空特征研究

东南亚地区是中国“一带一路”倡议的必经通道,也是我国发展对外经贸的重要节点区域,具有重要的战略地位.基于NPP／VIIRS夜间灯光数据,运用重心、标准差椭圆以及莫兰指数等空间分析方法,分析2012—2021年东南亚国家经济发展的时空特征.结果表明:东南亚国家GDP与夜间灯光数据之间存在显著相关性;从东南亚经济发展方向特征来看,东南亚经济重心整体向西北迁移,大部分灯光集中的中心已向东南亚的西北方向,即向中国的陆地边界移动了476 km,经济重心移动和“一带一路”倡议有关;东南亚总体经济体量增大,经济发展向区域内聚集,东南亚经济发展方向性愈发明显;从东南亚经济发展空间聚集性特征来看,高高聚集和低低聚集是东南亚经济发展最显著的两种空间聚集特征,高高聚集地区起到了很好的辐射作用,带动周边地区的经济发展,低高聚集区的发展潜力较大.研究时间段内,东南亚北部低低聚集区大幅度减少.

Housing the very poor or the young? Implications of the changing public housing policy in South Korea

Abstract

This paper discusses the reorganization of the roles of the national and local governments in public housing policy alongside decentralization, with particular reference to South Korea. Focusing on policy changes over the past decade, it reveals that rather than retrenchment amid a push towards greater local autonomy, the national government has diversified and expanded its public housing policy, and is increasingly pursuing a universal approach to public housing. Through case studies of Seoul and Gyeonggi, it also shows how the two local governments have become creative suppliers of public housing that is more customized to the local context. In particular, it highlights the rising emphasis on targeting young people rather than the very poor in public housing policies, a shift that is partly a legacy of Korea’s ‘productivist’ welfare state. The paper closes by discussing the implications of this latest policy trend, especially on local–national policy coordination.     

渝东南盆缘转换带金佛斜坡常压页岩气富集模式

近期,渝东南盆缘转换带金佛斜坡新完钻的页岩气井在上奥陶统五峰组—下志留统龙马溪组获得高产气流,地层压力系数为1.18,实现了该地区常压页岩气勘探的重大突破。为了评价该类型页岩气藏的勘探开发潜力,以钻井、物探和试气等资料为基础,解剖金佛斜坡页岩气藏基本地质特征和页岩气富集规律,总结常压页岩气富集高产主控因素,建立页岩气富集模式,并预测该区常压页岩气勘探开发有利目标区。研究结果表明:①该区优质页岩具有生气条件好、硅质矿物含量高、储层物性好、含气量高等特征,具有较大的页岩气勘探开发潜力;②常压页岩气富集高产具有"沉积相供烃控储、构造运动控保定富、地应力场控缝控产"的"三元控气"规律;③斜坡型目的层上倾方向发育封闭性反向逆断层遮挡有利于在断下盘形成较好的保存单元,随着埋深和离剥蚀边界距离的增大,页岩气富集程度和单井产量增高。结论认为,该研究成果丰富了常压页岩气地质理论,为中国南方复杂构造区尤其是斜坡型常压页岩气勘探开发提供了支撑。
