So far,more than 150 marine oil-gas fields have been found onshore and offshore about 350. The marine source rocks are mainly Paleozoic and Mesozoic onshore whereas Tertiary offshore.Three genetic categories of oil-gas reservoirs have been defined for the marine reservoirs in China:primary reservoirs,secondary reservoirs and hydrocarbon-regeneration reservoirs.And three exploration prospects have also been suggested:(1)Primary reservoirs prospects,which are chiefly distributed in many Tertiary basins of the South China Sea(SCS),the Tertiary shelf basins of the East China Sea (ECS)and the Paleozoic of Tarim basin,Sichuan basin and Ordos basin.To explore large-middle-scale even giant oil-gas fields should chiefly be considered in this category reservoirs.These basins are the most hopeful areas to explore marine oil-gas fields in China,among which especially many Tertiary basins of the SCS should be strengthened to explore.(2)Secondary reservoirs prospects,which are mainly distributed in the Paleozoic and Mesozoic of the Tarim basin,Sichuan basin,Qiangtang basin and Chuxiong basin in western China,of which exploration potential is less than that of the primary reservoirs.(3)Hydrocarbon-regeneration reservoirs prospects,which are chiefly distributed in the Bohai Bay basin,North Jiangsu-South Yellow Sea basin,southern North China basin,Jianghan basin, South Poyang basin in eastern China and the Tarim basin in western China,of which source rocks are generally the Paleozoic.And the reservoirs formed by late-stage(always Cenozoic)secondary hydrocarbon generation of the Paleozoic source rocks should mainly be considered to explore,among which middle-small and small oil-gas fields are the chief exploration targets.As a result of higher thermal evolution of Paleozoic and Mesozoic source rocks,the marine reservoirs onshore are mainly gas fields,and so far marine oil fields have only been found in the Tarim basin.No other than establishing corresponding marine oil-gas exploration and development strategy and policy, sufficiently enhancing cognition to the particularity and complexity of China's marine petroleum geology,and applying new thoughts,new theories and new technologies,at the same time tackling some key technologies,it is possible to fast and effectually exploit and utilize the potential huge marine oil-gas resources of China. 相似文献

在油气物化探勘查中,不确定性使得对勘查区的评价产生困难.物化探资料的使用可以减小这种不确定性,但不能消除它.在决策的各个阶段,使用物化探资料有助于提高勘查的效果及见油成功率.概率方法的引进可以改善现有勘查中的解释推断,使评价与决策定量化. 相似文献

欧佩克石油生产配额制度与油价关系研究 总被引：5，自引：4，他引：1
欧佩克(OPEC)是一个国际石油供应组织, 其石油政策的重点是通过实施生产配额制度, 对国际市场的油价进行控制, 以实现其石油收益的最大化。本文依据丰富翔实的历史及现状数据资料, 对欧佩克生产配额制度进行了深入研究后得出三点结论: 首先, 生产配额、产量与油价关系紧密, 欧佩克实施配额制度是其实施卡特尔控制的手段之一, 配额制度在欧佩克发展历史上发挥了重要作用, 尽管当前生产配额制度对油价的控制作用在一定程度上弱化, 但也正在发挥作用, 与此同时也存在一定的问题。其次, 欧佩克生产配额制度对油价的影响具阶段性特征, 本文分别对欧佩克在启动期、活跃期、挫折期、成熟期和彷徨期5个阶段中石油生产配额、产量与油价的关系进行了对比分析与研究, 得出了不同时期欧佩克生产配额、产量与油价的关系, 形成了若干重要认识。第三, 分析预测了未来欧佩克生产配额与油价的关系, 探讨了生产配额制度对世界市场油价走向的影响。 相似文献

柴达木盆地构造演化与石油富集规律 总被引：21，自引：4，他引：21
文章从构造体系出发,系统地研究了盆地周边山区构造,盆地基底构造、中、新生代盖层构造以及它们之间的联系,研究了古盆地、现代盆地的形成,发展和演化过程及其对中、新生代沉积的控制和生、储油条件。提出柴达木盆地中、新生代含油远景区主要分布在阿尔金山南缘盆地的西北部,并将其划分为六个二级含油远景较好的地段。同时提出中侏罗统是柴达木盆地主要油源,在德令哈凹陷和祁漫塔格山前的基底中可寻找古生代油源。 相似文献
