沁水盆地产层组合对煤层气井产能的影响

借鉴现有模型并结合沁水盆地现场实际，建立了煤储层双重孔隙多孔介质三维气、水两相耦合流动数学模型，研究了模型的全隐式解法，根据沁水盆地煤层和含水层的不同组合方式以及流体流动方式编制了7种组合方案，并利用自行编制的数值模拟程序对7种组合方案进行了单井产能数值模拟，最终确定将3号和15号煤层、K₂灰岩层联合作为产层是最优的组合方案.     

云南省玉溪盆地地下水防污性评价

随着地表水资源开发利用潜力降低和污染加剧,人类对地下水的开发利用程度不断增加,不同程度改变了地下水环境,尤其是城市地区的地下水环境有恶化趋势。采用DRASTIC指标体系和MAPG IS的空间叠加功能,对玉溪盆地地下水防污性进行评价,评价结果表明,该区地下水防污性总体在差—中等范围,可分为三种等级区。其中,盆地区地下水防污性基本在较差—差的范围,盆地周边山地防污性中等。反映人类工程和经济活动易对盆地地下水造成污染。     

台北凹陷异常高压形成机理探讨

在系统总结沉积盆地中异常高压形成机制的基础上,以台北凹陷为实例进行研究,表明:沉积盆地中形成异常高压的机制虽多,但对盆地大规模异常地层压力形成有决定作用的地质作用主要有欠压实作用、烃类生成作用和构造作用。

An investigation into the occurrence of sewage fungus in rivers containing papermill effluents—I. Review of previous research

Wastewaters from the manufacture of pulp and paper have given rise to problems of excessive microbial growth in rivers over a number of years. This paper is the first in a series of four articles describing research undertaken by PIRA at four U.K. paper/board mills (one integrated with pulp production) over the period 1978–1980. This first paper briefly reviews the published literature on sewage fungus growth from pulp and paper mill discharges up to 1978, but mainly describes previously unpublished work undertaken by PIRA over the period 1965–1975. This introductory paper thus provides a state-of-the-art review of methods to control sewage fungus growth from pulp and paper mill effluents prior to commencement of the research described in the following three articles.     

A model for the frequency of extreme river levels based on river dynamics

A new model for predicting the frequency of extreme river levels is proposed which encapsulates physical knowledge about river dynamics. The central idea is the use of continuous time stochastic processes that use hydrological equations and ergodic theory to model extreme events, rather than relying on statistical fits of classical models to local maximum data. A simple example shows how changes in discharge characteristics change the extreme river level frequencies. Solutions are provided for special cases, and directions for more general techniques are provided.     

Analytical fractionation of dissolved organic matter in water using on-line carbon detection

A routine method is described for the analytical fractionation of dissolved organic matter (DOM) in natural freshwater and in used waters. The fractionation is based on the different adsorption behaviours of various constituents of the DOM on octadecyl-silica as a function of pH. The DOM is separated into a hydrophilic, an acid and a hydrophobic fraction. The detection is carried out by an on-line carbon detector. The method requires only small water samples (20 ml) with low dissolved organic carbon (DOC) concentrations (1–5 mg Cl⁻¹). The samples can be analysed rapidly with no preconcentration. Fractionation of model compounds and mixtures demonstrates the performance of the method. The application of the method is illustrated by an investigation of the changes of the DOC composition occurring in a longitudinal transect of a river and during the infiltration of river water to groundwater.     

广州市东濠涌截污工程的设计

东濠涌为城区中集污水、雨水排放和防洪排涝功能于一体的合流河涌，东濠涌流域地处建筑物密集的旧城区。截污工程按照远近期相结合的原则设计：涌中上游为合流渠箱，下游为明涌截污，改善了两岸景观；在合流渠箱与明涌截污分界点处设置截污闸，晴天时污水流入两岸截污管，雨天时若截污管的流量大于2倍污水量则打开截污闸，合流水直排珠江；低洼地区和涌出口在雨期会受潮水顶托，采用泵排方式。该设计既满足了过流能力，又达到了截污整治的目的。
