赣南茅坪钨矿黑钨矿及共生石英中流体包裹体组合(FIA)研究

茅坪钨矿是赣南崇义-大余-上犹矿集区资源储量最大的矿床,主要由石英脉型矿体组成,为典型的石英脉型钨矿床.采用当前国际流行的"流体包裹体组合"(FIA)方法,对黑钨矿及共生石英中包裹体进行了显微测温和激光拉曼探针分析.结果表明,黑钨矿中原生包裹体均一温度普遍比共生石英高,指示了黑钨矿沉淀早于大部分共生石英,这一结论与岩相学结果一致.石英中包裹体记录了流体的早期不混溶和晚期混合,而黑钨矿中包裹体只记录了流体的简单冷却作用.流体的简单冷却是导致黑钨矿沉淀的主要机制.黑钨矿中除原生包裹体外,还发育少量次生包裹体,但黑钨矿中次生包裹体比共生石英中少.黑钨矿中次生包裹体均一温度、盐度与石英中原生包裹体均一温度、盐度相似,表明黑钨矿中次生包裹体形成于共生石英形成期间,记录了黑钨矿沉淀后的残余流体特征.

苏里格气田西区盒8段储层流体包裹体特征与成藏期次

通过单偏光显微镜观察、激光拉曼光谱分析及显微测温,对苏里格气田西区16口井50块盒8段储层流体包裹体样品进行了综合测试分析,总结了流体包裹体的岩相学特征,并依据流体成分将包裹体细分为6种类型。分别测试了不同层位、不同产状内与烃类包裹体伴生的盐水包裹体的均一温度、盐度。结果显示:盒8段储层伴生盐水包裹体的均一温度分布在90～180℃,温度主频段分布在120～170℃;石英次生加大边中的伴生盐水包裹体主峰温度比愈合裂隙及微裂隙中的略低,且不存在明显界限。在包裹体均一温度、盐度分析的基础上,结合研究区埋藏史-热史-生烃史,认为苏里格气田西区盒8段天然气为一期成藏,成藏期可依据伴生盐水包裹体均一温度分布特征划分为初始充注期和主充注期2个阶段。初始充注期伴生盐水包裹体均一温度区间为90～120℃,对应于220～160 Ma的中三叠世末—中侏罗世末,主充注期伴生盐水包裹体均一温度区间为120～170℃,对应于160～100 Ma的晚侏罗世—早白垩世末。

利用Linkam THMS 600型冷热台和LabRam-010型激光拉曼光谱仪,采用先进的包裹体测试技术及分析方法,对任丘油田雾迷山组地层储层流体包裹体进行了显微荧光、均一温度、冰点、拉曼光谱等分析测试,以确定雾迷山组储层油气充注时间及成藏期次,并利用数据对油气充注时古压力进行恢复.结果表明:该储层流体包裹体主要包括单相烃类包裹体、两相烃类包裹体、含饱和烃盐水包裹体及两相盐水包裹体4种类型;流体包裹体均一温度具有明显的双峰特征,峰值分别为70～90 ℃和110～120 ℃,盐度数据也集中在2个区域;沙二段及明化镇组沉积中期是主要成藏期;油气充注时的压力总体高于正常地层压力,但是并未造成异常高压.     

新疆白干湖钨锡矿流体包裹体特征及成因

白干湖钨锡矿床位于新疆祁漫塔格加里东褶皱带的转折部位,是东昆仑西段1个较好的钨锡(金)矿区,对白干湖矿区主成矿阶段形成的含黑钨矿石英脉中发育的包裹体进行岩相学及测温研究.研究结果表明:矿区主要发育3类包裹体:气液两相水溶液包裹体(I)、水溶液-CO2三相包裹体(Ⅱ)以及纯CO2两相包裹体(Ⅲ);Ⅰ型包裹体液相组分主要为NaCl水溶液,含少量KCl,其均一温度变化范围为160-310℃,盐度为1.82％～16.43％;Ⅱ型水溶液-CO2三相包裹体气相组分含有CO2及CH4等组分,均一温度为247～320℃,w(NaCl)为2.8％～9.4％;Ⅲ型CO2两相包裹体含量较少,均一温度为19.8～27.7℃;白干湖钨锡矿床成矿流体为中低盐度、中高温的NaCl-H2O-CO2体系.在成矿过程中,由于温度及压力降低,流体发生相分离成为较高盐度的水溶液流体和较低盐度的富CO2流体,钨锡成矿物质趋向于富集在中高盐度水溶液相中,并导致白干湖钨锡矿的成矿作用.     

鄂尔多斯白豹地区三叠系流体包裹体的特征及其在确定油气成藏期中的应用

为了确定鄂尔多斯盆地白豹地区三叠系延长组油气藏的成藏时间,采用了流体包裹体测温技术.通过对大量流体包裹体特征的研究,发现研究区的流体包裹体的均一温度有2期分布:85～105℃,115～125℃.从研究区延长组不同层位均一温度平均值对比来看,石英加大边中流体包裹体的均一温度显示出一个明显特点,即从长82→长81→长71,包裹体均一温度呈逐渐减小的趋势,而从长71→长63→长61→长4+5,均一温度又呈逐渐增加.这一变化趋势可能与油气的运聚有关.利用包裹体均一温度与油气成藏之间的关系,可推测油气藏的形成时间.研究区主要成藏期为早侏罗世中期—中侏罗世中期,中侏罗世末期-早白垩世早期.

Markedness and its Interpretation in Language Use

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.     

Features of Women's language

Language is a means of verbal communication. People use language to communicate with each other. In the society, no two speakers are exactly alike in the way of speaking. Some differences are due to age, gender, statue and personality. Above all, gender is one of the obvious reasons. The writer of this paper tries to describe the features of women＇s language from these perspectives： pronunciation, intonation, diction, subjects, grammar and discourse. From the discussion of the features of women＇s language, more attention should be paid to language use in social context. What＇s more, the linguistic phenomena in a speaking community can be understood more thoroughly.     

An Analysis of Catherine＇s Character——Wuthering Heights

Wuthering Heights, Emily Bronte＇s only novel, was published in December of 1847 under the pseudonym Ellis Bell. The book did not gain immediate success, but it is now thought one of the finest novels in the English language. Catherine is the key character of this masterpiece, because everybody and everything center on her though she had a short life. We can understand this masterpiece better if we know Catherine well.     

Lower Paleozoic oil relationships within Williston Basin, Canada

The Williston Basin is a significant petroleum province, containing oil production zones that include the Middle Cambrian to Lower Ordovician, Upper Ordovician, Middle Devonian, Upper Devonian and Mississippian and within the Jurassic and Cretaceous. The oils of the Williston Basin exhibit a wide range of geochemical characteristics defined as "oil families", although the geochemical signature of the Cambrian Deadwood Formation and Lower Ordovician Winnipeg reservoired oils does not match any "oil family". Despite their close stratigraphic proximity, it is evident that the oils of the Lower Palaeozoic within the Williston Basin are distinct. This suggests the presence of a new "oil family" within the Williston Basin. Diagnostic geochemical signatures occur in the gasoline range chromatograms, within saturate fraction gas chromatograms and biomarker fingerprints. However, some of the established criteria and cross-plots that are currently used to segregate oils into distinct genetic families within the basin do not always meet with success, particularly when applied to the Lower Palaeozoic oils of the Deadwood and Winnipeg Formation.     

低渗透非均质砂岩油藏启动压力梯度研究

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。     

On Tragic Consciousness In The Works By Ernest Hemingway

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.

Achieving Unusual States of Matter Under High Pressure

正The periodicity of the elements and the non-reactivity of the inner-shell electrons are two related principles of chemistry,rooted in the atomic shell structure.Within compounds,Group I elements,for example,invariably assume the+1 oxidation state,and their chemical properties differ completely from those of the p-block elements.These general rules govern our understanding of chemical structures and reactions.Using first principles calcula-     

Exchange-Correlation and Electronic Excitation Energies from Pairing Matrix Fluctuations

We have developed an adiabatic connection to formulate the ground-state exchange-correlation energy in terms of pairing matrix linear fluctuations.This formulation of the exchange-correlation energy opens a new channel for density functional approximations based on the many-body perturbation theory.We illustrate the potential of such approaches with an approximation based on the particle-particle Random Phase Approximation(pp-RPA).This re-     

Density Functional Theory for the Response of Periodic Systems to Electric Fields Based on the Vector Potential Approach

正The electronic and nuclear(structural/vibrational)response of 1D-3D nanoscale systems to electric fields gives rise to a host of optical,mechanical,spectral,etc.properties that are of high theoretical and applied interest.Due to the computational difficulty of treating such large systems it is convenient to model them as infinite and periodic(at least,in first approximation).The fundamental theoretical/computational problem in doing so is that
