油、水、干层的地球化学识别

本文介绍一种判断油、水、干层的地球化学方法，根据储层样品中有机抽提的的含量和组成特征，结合油层物性，地层测试和试油资料编制织识别油、水，干层的图版，提出判别油、水、干层的地质／地球化学指标，确定油层的地球化学参数的下限，并运用此方法对松辽盆地新站油田主要油层分布段的油、水、干层进行判别。根据试油资料验证表明，地球化学判断结果比传统的地质录井及地球物理测井资料判断结果更符合实际情况。     

水库水体生态系统数值模拟模型及其应用──以丹江口水库为例

反调节水库非恒定流数值模拟

采用二维水深平均方程组作为控制方程,利用边界拟合法进行坐标变换,采用有限体积法计算反调节水库的流场。在计算中,由于已知上游泵站抽水流量及下游枢纽供水流量,且上下游均找不到水位流量关系,上下游边界均为流速边界条件,没有压力边界条件,解不惟一,所以采用全水库水量平衡方程作为补充方程来补充定解条件。

River flow mass exponents with fractal channel networks and rainfall

An important problem in hydrologic science is understanding how river flow is influenced by rainfall properties and drainage basin characteristics. In this paper we consider one approach, the use of mass exponents, in examining the relation of river flow to rainfall and the channel network, which provides the primary conduit for transport of water to the outlet in a large basin. Mass exponents, which characterize the power-law behavior of moments as a function of scale, are ideally suited for defining scaling behavior of processes that exhibit a high degree of variability or intermittency. The main result in this paper is an expression relating the mass exponent of flow resulting from an instantaneous burst of rainfall to the mass exponents of spatial rainfall and that of the network width function. Spatial rainfall is modeled as a random multiplicative cascade and the channel network as a recursive replacement tree; these fractal models reproduce certain types of self-similar behavior seen in actual rainfall and networks. It is shown that under these modeling assumptions the scaling behavior of flow mirrors that of rainfall if rainfall is highly variable in space, and on the other hand flow mirrors the structure of the network if rainfall is not so highly variable.     

Auswirkungen des Ablassens von Hochwasserrückhaltebecken auf deren Limnochemie und Phytoplankton-Biozönose

Reservoirs have to be released when repairing of the dams is necessary. In 1995, two reservoirs in Baden-Württemberg (Germany) of similar age and volume (Lake Herrenbach near Göppingen, 1.0 Mio. m³ and Lake Breitenau near Heilbronn, 2.3 Mio. m³) were emptied. This allowed the singular possibility to investigate the effects of drainage and refilling on the limnochemistry and the phytoplankton biocoenosis of such artificial lakes.Before the drainage of the reservoirs, both lakes showed phosphorus release from the sediment during summer stagnation. Phosphorus values of Lake Herrenbach were regularly higher than those of Lake Breitenau (Lake Herrenbach 88 μg/l, Lake Breitenau 33 μg/l). During release, both lakes indicated higher phosphorus and chlorophyll concentrations as well as rising biomasses. Remarkable differences were observed during refilling of the reservoirs: while Lake Herrenbach showed higher transparency and lower phosphorus concentrations, Lake Breitenau progressed towards eutrophication (total phosphorus during summer 1996: Lake Herrenbach 30 μg/l, Lake Breitenau 55 μg/l). One reason for the reaction of Lake Breitenau was the reduced ground drainage during the refilling, which caused an accumulation of nutrients in the hypolimnion. Another reason was the mineralisation of vegetation which covered great parts of the dry lake sediment. The limnological change of Lake Herrenbach was not as clear but could be caused by the restauration of the pre-reservoir which was drainaged and dredged before the emptying of the main reservoir started as well as many other facts which differed Lake Herrenbach from Lake Breitenau.     

从岩相古地理论塔里木盆地西南地区石炭系油气潜景

石岩系是塔里木盆地西南地区重要的海相烃源岩和储集岩地层，油气潜力很大，但目前仅发现了1个气田、1个油田和2个油藏，勘探程度很低。本文在岩相古地理和地震地层学岩性岩相研究的基础上，对本区石炭系的烃源岩和储集岩的类型、分布及其与沉积环境的关系进行了研究，对盖层性质和分布，尤其对石炭系经过多次大的构造变动后所形成的油气潜景区进行了较深入的探讨，并指出4个有利的油气勘探地区，即巴楚隆起西端、玛扎塔克断裂带-海米-罗斯断裂带、麦盖提斜坡的北缘、南缘推覆体上盘。同时指出了各有利地区的勘探对策。     

铜街子电站水库诱发地震的判定及最大可能诱发地震震级的估计

对于水库围堰后猛然增加的地震活动，人们普遍关心两个问题，第一是这些地震的成因，第二是这些地震能对大坝安全性带来多大的影响。位于四川省乐山地区的铜街子电站在蓄水后地震活动骤然增高。本文通过对地震活动的分布范围、震源深度、震源机制解以及地震活动与库水水位变化之间的关系判定这些地震系铜街子电站蓄水后所诱发的地震。为了估计该水库所诱发地震的震级上限，本文通过定性预测方法和定量预测方法试图对诱震震级上限给出一个估计，但各手段所给出的结果却不完全一致，这说明目前的预测手段的不完善。在对各手段给出的结果进行综合分析之后，认为铜街子电站最大可能诱发地震震级上限在５．０级左右。当然，也可能以较小震级的震群型形式出现。
