陇东致密区水平井井眼轨迹与地层关系

鄂尔多斯盆地陇东地区长6X、长7Y储层纵向连续性差、横向上变化快,给水平井测井解释带来了一定难度。为了准确计算水平井储层参数,提高油层钻遇率,以研究区储层特征、测井资料为基础,围绕着水平井井眼轨迹与地层关系分析,给出了鄂尔多斯盆地致密油水平井储层划分建议,提出了储层各向异性分析步骤及计算方法,建立了水平井段分段分级评价方法,给出了水平井自然伽马、电阻率测井围岩校正方法,研究提高了水平井孔隙度、渗透率和含油饱和度等储层参数的计算精度,为水平井射孔段优化、提高水平井产能奠定了基础。     

Illiquidity Comovement and Market Crisis

This paper presents a rational expectation equilibrium model to explore how the financial contagion occurs between the unlinked markets that do not share common fundamentals. In the proposed model, the authors assume two of the three risky assets share no common fundamental factors, but are connected by one intermediate asset via cross fundamentals. Through this channel,investors transmit fundamental risk from one asset to another by dint of the cross fundamentals. This mechanism causes liquidit...     

Common Sentiment and Price Contagion

This paper investigates the informational role of prices in segmented markets which are shocked by a kind of common sentiment resulting from financial contagion. This common sentiment bridges the connection between prices learned by rational traders and thus can weaken the uncertainty from noise shock. The authors find that there exist comovement effect and crowding-out effect in information acquisition among different markets. These two effects capture financial contagion when markets experience large downward or upward tendency, which offers an explanation for market crisis to some extent.     

湖南康家湾金铅锌矿床成矿物化条件的研究

本文通过流体包裹体的系统研究与计算,确定了康家湾金铅锌矿床各成矿阶段的物化条件,其温度为264～139℃、压力为133～13bar、盐度11.00～3.34wt-％NaCl以及pH为6.62～7.66等。这为该矿床的形成和找矿提供了参考数值。     

市场操纵与噪声交易

基于DSSW模型的非有效市场构架,在信息市场操纵和社交网络的环境下,内生化情绪噪声交易者的投资决策,给出并分析跟随者与噪声交易者之间的均衡.结论显示:知情交易者操纵市场会增加价格的信息含量;非知情交易者操纵市场给价格带来噪声,价格的信息含量先增后减.适度悲观情绪是导致噪声交易者跟随交易的充分条件.此外,市场可能收敛到无噪声交易者、无跟随交易者、或噪声交易者和跟随交易者共存三种均衡状态.
