中国能够再造一个“大庆”

石油紧缺和价格高启迫使中国的研究机构和企业研究开发石油替代品。目前，安徽丰原集团等中国企业已基本掌握利用农作物精深加工全线替代石油产品的关键技术。     

Compositional and geochemical characteristics of light hydrocarbons for typical marine oils and typical coal-generated oils in China

Different types of crude oils have different light hydrocarbon compositional and geochemical characteristics. Based on the light hydrocarbon data from two kinds of oils, i.e., coal-generated oils and marine oils in China, light hydrocarbons in marine oils in the Tazhong area are generally relatively enriched in n-heptane, and coal-generated oils from the Turpan Basin are enriched in methylcyclohexane. The K1 values, reported by Mango （1987）, range from 0.97 to 1.19 in marine oils, basically consistent with what was reported by Mango on light hydrocarbons in terms of the majority of the crude oil data. But the K1 values of coal-generated oils are particularly high （1.35-1.66） and far greater than those of marine oils; heptane values in marine oils, ranging from 32.3% to 45.4%, and isoheptane values, ranging from 1.9 to 3.7, are respectively higher than those of coal-generated oils, indicating that the oils are in the high-maturity stage. In addition, expulsion temperatures of coal-generated oils from the Turpan Basin are obviously lower than those of marine oils from the Tazhong area.     

世界主要国家石油产量排名

美国《油气杂志》日前公布2009年度世界主要国家的石油产量,中国仅次于俄罗斯、沙特阿拉伯、美国,排名世界第四,占世界石油总产量的5．4％。根据中国石化协会最新发布的统计数据,2009年中国石油产量为1．89亿吨。     

不同扰动方式对沙砾质戈壁地表风蚀量的影响

通过野外风洞实验,测定了不同破坏方式、破坏面积和风速下的沙砾质戈壁风蚀量。结果表明：不同破坏方式引起的风蚀量不同,扰动强度越大造成的风蚀量越多;相同扰动方式下连续破坏造成的风蚀量稍高于间隔破坏。风蚀总量随破坏面积的增大而增加,且服从指数函数。风速为8～10 m·s^-1时,扰动的戈壁地表以轻微侵蚀为主;10～12 m·s^-1 是风蚀量增幅最大阶段;当风速大于 12 m·s^-1时,以强烈风蚀为主。风沙流中沙物质的主体是细沙和极细沙,在20 cm高度范围内,自风沙流下层至上层细沙含量比较稳定,极细沙含量逐渐降低,中沙含量逐渐上升。     

生产井蒸汽吞吐提高火烧油层效果

在阿尔伯达东北的冷湖油砂沉积带地区，英国加拿大石油资源有限公司实施了用单井蒸汽吞吐改善火烧地层动态，保护生产井免受燃烧前缘或氧气估破伤害的方案。其效果是多方面的。本论文描述了采用注蒸汽的开发效果和典型实例，得出了如何蒸汽吞吐最有效的结论。     

大亚湾大鹏澳水体石油烃含量变化及其与环境因子的关系

根据对该水体中石油烃及各种环境因子DO、COD、BOD5、DIP、DIN、Chl-a含量的测定结果，描述了石油烃的分布特征讨论了环境因子和石油烃含量之间的关系，结果表明，石油烃的含量在海域中呈现出由湾内向湾外逐渐降低的趋势，且环境因子和石油烃含量之间存在着一定的线性关系。     

论沙粒两种起动关系与沙粒跃移的双重性

研究沙粒两种起动关系是深入认识沙粒两种起动效能的继续和发展。文章分析了沙粒两种起动的不同性质，首次把流体起动界定为风蚀性起动，把跃移质冲击起动界定为置换性起动。认为流体起动具有主动分异性，而冲击起动只有随机分异性。根据这些特性对沙粒两种起动效能和沙粒连续移动提出了新义。认为沙粒跃移具有双重性，跃移质有其冲击地表的一面，也有其大量耗能的一面。沙粒两种起动具有兴衰与共的不可分割关系。地表风蚀是沙粒两种起动优势互补相互促进的结果；而地表堆积有时是跃移质耗能过多引起两种起动互相制约的结果。通过多方论证，将沙粒两种起动效能之由传统的19：1，初步改为4：1乃至3：1。     

Classification of Grove Mountains meteorites and its significance

Meteorites are the extraterrestrial rocks, which provide insights into the origin and evolution of the solar system. During the past half century, a great number of meteorites has been discovered on the Antarctic Ice Sheet, confirming that the Antarctica is the most important meteorite concentration area on the earth. Since the first four Antarctic meteorites were found in Grove Mountains in 1998, a total of 9834 meteorites have been collected by four subsequent expeditions. It opens a new field of meteorite study in China, and also accumulates a great deal of scientific samples for China. Recently, classification of Grove Mountains meteorites has been carried out for 6 years, and made following progresses: (1) 2433 meteorites, which include many special meteorites, e.g. Martian meteorites, ureilites and carbonaceous chondrites, have been classified. (2) the Antarctic meteorite curation and the sample sharing system are set up preliminarily. (3) the classification procedure, the management of meteorite samples, and the application procedure for the Antarctic meteorites are completed after the systematic classification during these years. (4) young generation researchers on meteorite are trained through the cooperation of many universities and institutes on meteorite classification.
