湘江流域作为湖南省经济发展的依托和基础,根治其污染状况是建设"两型社会"的首要目标。创新湘江流域污染治理机制,探索从源头上解决湘江污染的长效途径,既顺应可持续发展的大势所趋,也可为全国江河流域污染治理作出应有的示范。经过三年的集中整治,湘江流域水污染治理取得了显著成效,但污染问题依然突出,离建设"两型社会"的目标仍有较大差距。湘江流域污染治理中存在的主要问题在于观念和机制。
针对油藏高温条件下微生物数量较少,驱油机理不够明确的特点,对胜利油田不同区块微生物进行筛选.得到一株能够乳化分散原油的细菌,经鉴定为嗜热脂肪地芽孢杆菌,能够耐受60℃以上的高温并能有效生长代谢,代谢产物主要由糖类、脂类和蛋白质组成.利用该菌的培养液、培养后代谢产物及培养后的菌体分别进行驱油实验,结果表明3种不同的驱替液均能够提高驱替效率,其中培养液能够提高驱替效率11.8%,其他两种驱替液提高驱替

靖边气田碳酸盐岩储层原始沉积以泥微晶灰岩为主,物性极差而难以成为储层。其储集性能主要源于后期复杂成岩作用的影响,经历了不同类型的成岩作用,对应的孔隙结构复杂多样,这为有利储层的预测带来很大困难。采用铸体薄片、扫描电镜、阴极发光、物性和高压压汞等分析测试资料,综合研究了靖边气田北部马五1亚段碳酸盐岩储层的成岩作用类型,及其形成的储集层微观孔隙结构特征。研究表明,马五1亚段储层主要经历了机械压实和压溶
