松辽盆地大陆科钻二开段大井眼钻井液技术

CCSD-SK2井是一口钻穿松辽盆地白垩纪陆相沉积地层的中国大陆科学钻探井。二开段先以216mm口径钻至2806.20m,然后进行444.5mm口径扩孔。泥页岩地层大井眼钻进过程中粘土矿物含量高且易造浆,砂砾岩层渗透性强易粘卡,井壁稳定控制与钻屑携带难度大。选用了钾铵聚合物钻井液体系和聚磺钻井液体系,通过正交实验确定了钻井液配方。将钻井液控制在合适的密度、较低的失水量以及较强的封堵性,有效实现了井壁稳定;保持适当的环空返速、较高的动塑比以及定期打稠塞举砂等措施,有效实现了井眼净化。1086.45m~1147.56m与1182.74m~1256.01m井段累计收获岩心130.90m,取心率达到97.41%,平均机械钻速为0.84m/h;最终顺利钻至2806.20m。

中国旅游科技创新的时空结构、重心轨迹及其影响因素研究

旅游产业是充满众多科技创新与成果转化的社会经济部门。以我国旅游产业相关发明专利、旅游收入、风景名胜区、高校学生数等为分析依据,基于地理集中指数、动态变动指数、空间重心模型和灰色关联分析等方法,对各省区2006—2017年旅游科技创新的时空结构、重心轨迹及其影响因素等进行实证研究。结果表明：时间上,我国旅游科技创新整体上呈波动上升的发展态势,2013年后地理集中度指数开始持续下降;空间上,旅游科技创新在我国呈东高西低、南高北低的分布格局。此外,旅游科技创新的空间重心位于我国华东地区,并呈先由北向南、再由东向西的移动轨迹。最后,科技创新产出、旅游经济水平、科技经费投入、经济宏观环境、科技创新服务、旅游资源禀赋等要素指标均对我国旅游科技创新产生一定影响,但影响程度具有差异。

能源盆地沉积学及其前沿科学问题

赋存油、气、煤和（或）铀能源矿产的沉积盆地,称为能源盆地。沉积作用及建造是影响油气煤铀同盆共存、成藏及分布的重要因素和物质基础。能源等沉积矿产及其形成,是沉积学的重要组成部分。通过讨论能源盆地沉积建造与油气煤铀赋存成藏及分布的内在联系,提出成煤建造在盆地演化和空间分布上,总体处于成油气建造和成铀建造的过渡、衔接部位和承前启后的演化阶段。并探讨了厚煤层的初始成煤物质来源与成因,蚀源区物源对盆地沉积建造、油气储层和铀成矿的重要影响。分析认为当前存在重先进技术观测测试,轻露头区精细剖析的倾向;对后期改造的影响程度和原盆古沉积面貌恢复的水平尚需重视和提高。能源盆地沉积学内涵的自然外延领域广阔,与之相关的前沿科学问题颇多。应将沉积学置于盆地形成演化和改造的时空过程中,兼顾地球环境和生物演变进程,进行整体、动态、综合研究。重点讨论了其中部分相关前沿科学问题,如:沉积盆地动力学、地球环境及生命演变对沉积和成矿作用的影响、有机与无机相互作用对能源矿产形成的影响、事件沉积学及深部作用与成矿作用的关联、能源矿产空间分区性及偏富极形成的沉积学环境、沉积建造和沉积矿产年代学等。

Popular Culture,Geopolitics, and Identity

Abstract

This study aims to theoretically investigate the notion of critical thinking for a more just understanding of self and “others” in global geographical learning. It focuses on the kinds of injustice in the world which are driven by our relationships with “others.” By drawing on the literature of critical education, philosophy of education, and geography education, this study reveals how universal notions of criticality tend to easily undermine those perceived as global others and may highlight, in deficit mode, their perceived differences. Instead, the study presents the imperative of deconstructive thinking for a more just world. The article concludes by proposing a teaching strategy for alternative criticality which strives for justice in school geography.
