During peak pollution period, mercury levels in water, sediment and fish body of these rivers were close to or even higher than that of famous Minamata Bay of Japan. Some residents who live near to the polluted rivers were affected and the methyl mercury values in their blood, hair and urine were higher than normal people obviously . Since the fish had decreased even vanished in these rivers, so the food chain that transfers mercury to human also was out off almostly. However, nervous symptoms of Minamata disease were discovered among fisherman who had eaten more fishes. This report relates the stories about the mercury pollution of the Second Songhua River and Ji Canal.展开更多
A井区位于鄂尔多斯盆地西部,是长庆油田的重要油气产区之一,马家沟组是该井区的主力油气储层,属低孔、低渗储层。论文通过常规物性实验、压汞实验和铸体薄片观察测定实验对所取的260余块岩心样品进行检测分析,得到了A井区马五段的孔渗...A井区位于鄂尔多斯盆地西部,是长庆油田的重要油气产区之一,马家沟组是该井区的主力油气储层,属低孔、低渗储层。论文通过常规物性实验、压汞实验和铸体薄片观察测定实验对所取的260余块岩心样品进行检测分析,得到了A井区马五段的孔渗值、孔隙特征和储层矿物成分以及孔隙类型情况。研究表明:马五段储层孔隙度平均值为3.78%,78.3%样品的渗透率小于0.5 m D,测得所选样品平均孔喉半径值为5.17μm,而且分选性差。马五段储层为碳酸盐岩,所含矿物类型有白云石、方解石、泥质、硅质、伊利石和黄铁矿等,镜下观察到的孔隙类型有溶缝、溶孔、溶洞、膏模孔及构造裂隙,常伴随不同矿物的结晶充填。展开更多
