洛带气田蓬莱镇气藏开发部署优化研究

气藏评价尚未结束之前，开发的早期部署工作非常困难。针对洛带气田蓬莱镇组气藏的开发部署工作，利用目前许多新方法对开发层系划分、采气规模、开发规划、合理配产和井网部署等进行了优化研究，对气藏开发提出了指导性意见，且对类似气藏也具有参考意义。     

青藏高原北羌塘半岛湖新生代粗面玄武岩橄榄石电子探针和激光探针分析

利用电子探针和激光探针剥蚀系统（LA-ICP-MS），对北羌塘新第三纪粗面玄武岩中的橄榄石主元素和微量、稀土元素进行了系统分析。结果表明，本区橄榄石Fo平均为88，属贵橄榄石种属。相对富集Ni、Co和重稀土，而强烈亏损轻稀土及Rb、Sr、Ba、Zr等大离子亲石元素。其稀土元素配分型配分型式与粗面玄武岩全岩稀土配分型式呈互补状态。     

机械研磨对平鲁煤系高岭石热行为的影响

对煤系高岭石进行0-2h的研磨之后，再在900℃、1000℃、1400℃的温度条件下分别对其加热1h，然后利用X射线衍射（XRD）、差热分析（DTA）、红外光谱（IR）等手段，研究机械研磨对于煤系高岭石晶体结构的破坏作用以及对其热行为的影响。结果显示，煤系高岭石被研磨1h之后，高岭石的晶体结构几乎全部跨塌。把研磨1h的煤系高岭石加热到1000℃（加热1h），便能形成结晶良好的莫来石。     

Division of Gas Accumulation System and Laws Controlling Distribution of Natural Gas in Typical Petroliferous Basins of China

Considering the existing problems of the petroleum system, this paper brings forward the concept of natural gas accumulation system and presents the dividing principles. Then detailed statistics on the accumulation factors of the 32 typical natural gas accumulation systems in China and studies on the laws controlling distribution of gas are collected. The research shows that the petroleum accumulation system is the basic unit controlling petroleum generation, migration and accumulation. Generating intensity, generating amount, accumulating efficiency and migration distance plays an important role in the distribution of natural gas. Through analysis on results of resources evaluation, discovered reserves and residual reserves, potential areas in middle-scaled petroliferous basins in China are forecasted in this paper. Ordos, Sichuan, Tarim and Qaidam basins are found out to be the main basins developing and enriching gas accumulation systems.     

Milan: The city of constant renewal

Traditional models of urban development are no longer adequate to describe current metropolitan transformations. These are now at the centre of a debate concerning management and administration. In Italy, delays in resolving problems of urban and metropolitan government, despite the legal framework provided by Law 142/90, have weighed heavily on the larger urban areas of the country: Rome, Naples, Milan, which have not been able to tackle the issue of metropolitan government. Recent legislation, while not providing a pre-defined institutional solution, allows separate administrative districts to collectively establish metropolitan institutions of `variable geometry'. The Milan urban area is not one city, but a system of mutually-dependent cities, linked to each other and the rest of the world by a transport network still requiring much investment. The vitality of its economic structure (especially its small firms) is held back by seriously inadequate infrastructure and low external economic efficiency. The provincial capital may boast `historic centrality' but the most interesting potential for development is to be found on the periphery and in the administrative districts immediately surrounding it, in the recovery of derelict industrial areas and dormitory towns established in the 1950s and 1960s, especially to the north. Recovery of derelict areas, green areas, and better transport links within the urban area and with the outside world are the key elements in the reorganization of `Greater Milan'. In this situation of rapid transformation the most appropriate political strategies involve negotiated planning.

深井水氡主要干扰因素及映震效能分析

对甘肃省玉门青6井和平凉泾川泾3井两口深水井的水氡及辅助项目观测资料采用多元逐步回归、相关距平、一阶差分等方法进行处理，分析并排除了主要干扰因素，显示出两井在肃南5.4级、托莱6.0级和礼县5.1级地震前有明显异常，对两井的映震效能和地震预报前景进行了评价。     

山西夏县台热水井水氡异常特征与地震的关系初探

为弄清山西夏县中心地震台水氡震前异常的原因 ,对山西夏县中心地震台热水井水氡 1984年以来的观测资料用概率论的数据处理方法进行了处理 ,以负异常的发震原理进行了分析 ,结果表明震前负异常的发震概率为 70 %。     

云南水汞在姚安6.5级地震前的异常特征分析

对2000年1月15日姚安6．5级地震前后云南水汞异常进行分析研究，结果表明：在9个观测台站中，地震前有1个观测台站的水汞出现中期趋势异常，1个台站的水汞出现远震异常，4个台站的水汞出现短期异常，1个台站的水汞出现临震异常。地震前3个月内，水汞短期异常有活跃，平静的过程，在平静中(仅1个台站出现临震异常)发生姚安6．5级地震。姚安地震发生在距出现远震异常的水汞观测台站70km的地方。出现远震异常的水汞观测台站附近，可能是未来强震的发震地区。
