HYDROCARBON MIGRATION AND CHARGE HISTORY IN THE KARANJ,PARANJ AND PARSI OILFIELDS,SOUTHERN DEZFUL EMBAYMENT,ZAGROS FOLD-AND-THRUST BELT,SW IRAN

This study investigates the charge history of the Oligocene – Lower Miocene Asmari Formation reservoir at three oilfields (Karanj, Paranj and Parsi) in the southern Dezful Embayment, SW Iran, from microthermometric analyses of hydrocarbon-bearing fluid inclusions. The Asmari Formation reservoir was sampled in seven wells at depths of between 1671.5 and 3248.5 m; samples from three of the wells were found to be suitable for fluid inclusion analyses. The samples were analyzed using an integrated workflow including petrography, fluorescence spectroscopy, Raman microspectroscopy and microthermometry. Abundant oil inclusions with a range of fluorescence colours from near-yellow to near-blue were observed. Based on the fluid inclusion petrography, fluorescence and microthermometry data, two episodes of oil charging into the reservoir were identified: 7 to 3.5 Ma, and 3.5 to 2 Ma, respectively. Fluid inclusions in general homogenized at temperatures between 112 and 398°C and with salinities of 14 to 23 wt.% NaCl equivalent. Based on the burial history, the Albian Kazhdumi and Paleogene Pabdeh Formation source rocks in the study area have not reached the gas generation window. The abundant fluid inclusions containing gas-liquid phase observed in the Asmari samples studied are therefore inferred to have been derived from secondary oil-to-gas cracking which resulted from Late Pliocene uplift.     

塔里木盆地顺1走滑断裂带超深储层油气充注历史

顺北地区是近期塔里木盆地超深层油气勘探获得重大突破的领域。通过顺北地区奥陶系一间房组储层原油和天然气地化特征对比,并结合荧光颜色和显微荧光光谱参数分析,认为顺北地区奥陶系经历了多期油气充注,且早期充注原油遭受一定程度的生物降解,而天然气为原油伴生气。利用类异戊二烯烃、生物标志化合物和原油轻烃对顺北地区和顺南地区原油进行对比,发现顺北地区油气来源与顺南地区一样来自于寒武系玉尔吐斯组烃源岩,通过断穿寒武系的断层向上运移至奥陶系储集层。对顺北地区采集样品进行流体包裹体测试、冷阴极发光、荧光观察等系统分析,结果表明顺北地区发生了“五幕三期”油充注和一期天然气充注,第一期为加里东晚期,第二期为海西晚期,第三期为喜马拉雅晚期,而天然气充注发生在喜马拉雅晚期。     

流体包裹体在松辽盆地成藏期次研究中的应用

利用流体包裹体在储层中的种类、含量、分布等常规特征以及它们与成岩矿物的结构关系,可以分析油气运移及圈闭充注模式;根据包裹体的均一温度并结合盆地的古地温史和埋藏史,可以确定油气成藏期次。应用显微—红外光谱技术、包裹体的鉴定和均一温度测定技术,分析了松辽盆地中浅层和深层样品的包裹体。同时利用红外光谱的有关参数划分了各井包裹体的油气成藏期次,结果与镜下鉴定结论相一致,并确定了其中油气包裹体的成熟度。同时利用流体包裹体均一温度并结合埋藏史和古地温史,研究了松辽盆地部分地区油气成藏期次。

论作为学术思潮的观念史研究方法

在不到一个世纪的时间里,观念史研究方法逐渐渗透到文学、史学和哲学诸领域,形成一个较大的学术研究思潮。由于以美国的洛夫乔伊和英国的斯金纳为代表的观念史研究专家的不懈努力,观念史研究成果使各学科摆脱近代以来被科学主义思潮切割分裂的状态,以某种新的方式实现新的整合成为可能。观念史研究方法对中国学术的影响经历了几个阶段:先对文学研究,接着对历史学研究,然后对哲学研究产生影响。     

籽用南瓜种子发育过程中脂肪酸积累模式

以籽用南瓜品种银辉一号为材料对南瓜种子发育过程中脂肪酸的累积过程进行了分析。结果表明,成熟的南瓜种子中可检测到8种脂肪酸,按含量高低依次为：油酸、亚油酸、棕榈酸、硬脂酸、花生酸、豆蔻酸、棕榈油酸、亚麻酸。南瓜种子粗脂肪含量的积累模式呈现升-降-升的Z字型变化模式。在累积过程中除了C18∶1和C18∶2有负相关性外,其它脂肪酸相互之间显示了高度的正相关性。

西汉徐地鲁恭王宫苑园林——鲁灵光殿研究

汉代是中国园林的形成阶段,不仅园林建筑物有所增加,成为住宅的延伸与扩展,而且人工造景比重也增大,造园要素趋于完备。园林的内容与功能随着社会生活的改变而逐步多样和完善,不仅是射猎、走狗、跑马的场所,还可以是游船、宴乐、赏鱼虫走兽、观看百戏的地方。造园在布局上也采用灵活多变的手法,按功能的需要,穿插安置不同形式的厅堂、楼阁、亭榭等。通过对鲁灵光殿时代背景及汉代园林、建筑营造形式的深入研究,结合文献的相关记述,梳理出鲁灵光殿的沿革,并以此为依据,对鲁灵光殿进行复原。
