深部含油气性的几个问题

根据蒂曼—伯朝拉和西西伯利亚含油气省深井、超深井资料,介绍了深层构造、储集层、烃源岩及生油气潜力等方面的最新研究成果;分析了预测的生烃潜力与实际情况不一致的原因;给出了地层中的游离甲烷和伴生甲烷在一个较宽深度范围内的分布资料;指出了在评估深层和超深层钻探前景时,单独预测其油气潜力的必要性;在研究俄罗斯深部油气潜力时,应进行超深井钻探,其钻探成果具有很高信息价值     

激光粒度仪在塔里木泥浆工艺中的应用

为了深入了解泥浆固相颗粒大小及级配,并能迅速选择合适的高分子聚合物,引进了CILAS—920型激光粒度仪。通过膨润土分散实验、高分子聚合物包被抑制性评价实验及现场泥浆粒度分析检测等,对该仪器在泥浆中的应用进行了初步探索。     

江西省1998年防汛工作总结

１９９８年江西省天气异常，发生了继１９５４年以来又一次特大洪涝灾害，赣江，抚河，信江，饶河，鄱阳湖和长江相继超过历史最高水位，且长江，鄱阳湖水位长期居高不下，洪涝灾害范围之广，强度之大，损失之重，时间之长为建国以来所罕见，本文全面总结了江西省１９９８年防汛工作，并提出了今后防汛工作亟待解决的问题。     

吐哈盆地英1井西山窑组砂岩中沥青的荧光特征及成因

吐哈盆地台南凹陷吐玉克稠油油田北侧钻探的英1井,在中侏罗统西山窑组取心见到了少量含沥青砂岩。笔者利用荧光显微镜对沥青产状及荧光特征进行观察描述,结合区域地质条件的分析研究,得出了砂岩中的沥青是经过剥蚀搬运后再沉积的结论     

Determining priorities for family physician education in substance abuse by the use of a survey

As the initial stage in developing a curriculum to assist family physicians to diagnose and manage alcohol abuse in their practices, questionnaires were mailed to a selected group of family physicians. A total of 117 physicians (34%) completed the questionnaire. The majority of physicians (70.1%) reported that fewer than 10% of their caseload experienced alcohol-related problems. Most physicians (59.3%) did not use any of the standard diagnostic instruments but reported that screening and detection was the most challenging alcohol-related problem along with patient management. The questionnaire identified a number of areas that could be used in the development of educational strategies to increase the expertise of primary care physicians in the diagnosis and management of alcohol-related problems.     

Comprehensive benefit of flood resources utilization through dynamic successive fuzzy evaluation model: A case study

Taking the flood resources utilization in Baicheng, Jilin during 2002–2007 as the research background, and based on the entropy weight and multi-level & multi-objective fuzzy optimization theory, this research established a multi-level & semi-constructive index system and dynamic successive evaluation model for comprehensive benefit evaluation of regional flood resources utilization. With the year 2002 as the base year, the analyzing results showed that there existed a close positive correlation between flo...
