优化改造油田生产工艺 增产增效提高环保水平——涠洲11-4油田生产工艺优化改造实践

油田生产水处理和海管输油能力不足是制约涠洲11-4油田生产和影响生产安全的瓶颈问题。合理利用油田原有设施和条件,对生产水处理系统和输油管道系统进行工艺优化改造,使该油田B平台海管运行的安全可靠性得以明显提高,并使油田生产水处理能力和处理质量得到有效改善,同时大幅度降低了油田生产成本,拓宽了油田增产挖潜的空间。涠洲11-4油田优化改造生产工艺实践经验,可为进一步拓宽海上老油气田的生产管理思路提供参考。

Urban growth and environmental degradation: The case of Cairo, Egypt

The immense growth of cities, especially in developing countries, is resulting in the urbanization of both poverty and environmental degradation to a greater degree than ever before. This paper examines the processes of growth and degradation in the Greater Cairo Metropolitan Region (GCMR), currently the world’s tenth largest mega-city. It reviews the region’s growth and selected environmental issues as well as impacts of current efforts on managing the region. The assertion of this paper is that current management policies and bodies lack a comprehensive view of urban governance for the region, which does not bode well for the future environmental and economic sustainability of the region.     

解放前我国学者对新疆石油地质的调查和研究

20世纪初，随着近代地质学在中国的形成和发展，一些学者开始了对新疆石油地质的调查和研究，30年代末以前，翁文灏，章鸿钊等学者利用文献和间接获得的资料，对新疆石油资源进行了宏观考察和若干重要油苗的地质研究；40年代开始，黄汲清等地质家在新疆进行实地考察，对独山子油田进行了详细研究，并在南北疆部分地区进行了路线性石油地质调查。     

提高综合勘测实力开拓岩土工程市场

随着西北勘测设计研究院（以下简称西北院）勘测总队所承担的黄河龙￣青段、白龙江流域等河段前期综合勘测工作的相继结束，拥有２０００多名职工的勘测队伍面临着何去何从的重大选择。在此转折关头，勘测总队面对现实，审时度势，抓住机遇，开拓前进，及时转轨变型，制定了本单位发展的战略和方向，使勘测总队由单一勘测业务转变为集勘测与岩土工程施工为一身的新型综合队伍。几年来，经过全体职工的奋发努力，缍获得了１９９５年￣     

Water quality assessment of a recently refilled reservoir: The case of Bütgenbach Reservoir, Belgium

Bütgenbach Reservoir is situated in the High Ardennes plateau in eastern Belgium (50°25′N; 6°13′E). It is used principally for flood control and for production of hydroelectric energy. It has been subjected to a previous series of studies because of its eutrophication problems and their impacts on the local economy. Bütgenbach Reservoir was emptied during spring 2004 for dam restoration, being refilled in mid‐September of the same year. Selected physicochemical and biological parameters (temperature, dissolved oxygen, pH, inorganic and organic nutrients, chlorophyll‐a) were measured fortnightly during the lake's productive season (mid‐April to mid‐October 2005) at three sampling sites throughout the water column. The water quality conditions after refilling of the lake were compared to previous studies accomplished at the same sampling sites (prior to emptying the lake). The actual trophic status was mesotrophic to eutrophic, based on the combination of total phosphorous and chlorophyll‐a concentrations, as well as water transparency. Bütgenbach Reservoir generally exhibits good water quality, based on the French water quality system SEQ‐eau. A longitudinal decrease in water quality was observed from upstream to downstream, because mainly of the differences in lake bottom morphology and water residence time, and their impacts on nutrient distribution in the lake.

环境友好油层保护钻井液的研究及应用

针对江苏油田地层特性和地面生态环境具体情况开展了钻井液防塌性能、油层保护与环境保护的协同研究。在研制和筛选能满足环境保护要求的钻井液处理剂如润滑剂、降滤失剂和油层保护剂等的基础上,通过配方优化研制出了环境友好油层保护钻井液体系,并进行了防塌、油层保护、裂缝封堵等性能的室内评价。评价结果表明:该钻井液体系具有较强的抑制泥页岩膨胀和分散能力,渗透率恢复值大于85%,润滑性及滤失性好,而且无生物毒性,化学毒性低,易生物降解。应用该钻井液体系在江苏油田AF地区进行了现场试验,现场应用表明,该钻井液体系防塌性和油层保护效果好,各项环境指标达到农用污染标准,可直接排放,从源头控制了钻井液的污染,可进一步推广应用。
