下扬子黄桥地区上古生界油气成藏研究

通过平衡剖面法、流体包裹体分析、地化分析以及物性测试对下扬子黄桥地区的构造演化、油气成藏史、成藏类型及成藏主控因素进行了研究。黄桥地区构造演化经历了平稳隆降、挤压推覆、拉张裂陷3大时期;黄桥地区存在2期油气充注的历史,燕山晚期至喜山期油藏形成,晚喜山期上古生界内幕油气藏得以保存并最终定型。该区HT3井油藏属于龙潭组自生自储型油藏,构造是油气成藏的主要控制因素,物性是控制油藏分布的重要因素。      

塔里木盆地轮古地区轮深2井蓬莱坝组沥青浸染样式

摘要：在塔里木盆地轮古地区,轮深2井下奥陶统蓬莱坝组岩心存在大量的沥青浸染。通过详细观察下奥陶统蓬莱坝组两个回次的岩心,认为存在6种类型的沥青浸染样式。它们分别是：沿着水平纹层浸染、沿着微裂缝纹层复合浸染、沿着裂缝浸染、沿着溶孔浸染、沿着压溶裂缝浸染以及沿着拉分空间块状浸染。不同类型的沥青浸染样式具有不同的成因以及油气富集意义。这些现象说明蓬莱坝组曾经有过油气充注历史,由于富集空间类型的差异使得沥青样式出现不同类型。通过轮深2井蓬莱坝组白云岩的沥青浸染样式分类以及储层成因意义分析,可以为该地区白云岩储层精细表征提供地质依据。研究认为硅质岩是导致蓬莱坝组钻时增大的主要原因,同时蓬莱组实际取心沥青浸染样式可以说明之前预测的“串珠”状白云岩储层不是有利储层。     

Production of hydrogen rich bio-oil derived syngas from co-gasification of bio-oil and waste engine oil as feedstock for lower alcohols synthesis in two-stage bed reactor

High efficient production of lower alcohols (C₁–C₅ mixed alcohols) from hydrogen rich bio-oil derived syngas was achieved in this work. A non-catalytic partial oxidation (NPOX) gasification technology was successfully applied in the production and conditioning of bio-oil derived syngas using bio-oil (BO) and emulsifying waste engine oil (EWEO) as feedstock. The effects of water addition and feedstock composition on the gasification performances were investigated. When the BO₂₀ and EWEO₃₀ was mixed with mass ratio of 1: 0.33, the maximum hydrogen yield of 93.7% with carbon conversion of 96.7% was obtained, and the hydrogen rich bio-oil derived syngas was effectively produced. Furthermore, a two-stage bed reactor was applied in the downstream process of lower alcohols synthesis from hydrogen rich bio-oil derived syngas (H₂/CO/CO₂/CH₄/N₂ = 52.2/19.5/3.0/9.4/15.9, v/v). The highest carbon conversion of 42.5% and the maximum alcohol yield of 0.18 kg/kg_cat h with selectivity of 53.8 wt% were obtained over the Cu/ZnO/Al₂O₃(2.5)//Cu₂₅Fe₂₂Co₃K₃/SiO₂(2.5) catalyst combination system. The mechanism and evaluation for lower alcohols synthesis from model bio-oil derived syngas and model mixture gas were also discussed. The integrative process of hydrogen rich bio-oil derived syngas production and downstream lower alcohols synthesis, potentially providing a promising route for the conversion of organic wastes into high performance fuels and high value-added chemicals.

塔里木盆地西北部下寒武统白云岩特征及多重白云石化模式

塔里木盆地下寒武统白云岩储层研究尚处于起步阶段,开展白云石化模式系统研究对于明确白云岩储层特征具有重要意义。基于露头观察、岩石薄片鉴定、主量元素、微量元素、稀土元素和碳、氧、锶、镁同位素等资料,对塔里木盆地西北部下寒武统白云岩特征和成因模式进行了系统分析。塔里木盆地西北部阿克苏露头区下寒武统发育微生物白云岩、泥晶白云岩、粉晶—细晶白云岩和中—粗晶白云岩4类白云岩。微生物白云岩属于典型微生物白云石化成因模式,白云石化流体以海水为主。泥晶白云岩、部分粉晶—细晶白云岩和少量中—粗晶白云岩属于典型蒸发泵与回流渗透白云石化成因模式,白云石化流体以回流卤水和海水为主。绝大多数中—粗晶白云岩和部分粉晶—细晶白云岩属于埋藏热液白云石化成因模式,白云石化流体为与烃类充注相关的地层卤水及陆源水。早成岩阶段微生物白云石化作用和蒸发泵与回流渗透白云石化作用是塔里木盆地西北部阿克苏露头区下寒武统微生物白云岩和粉晶—细晶白云岩孔隙发育的基础。     

Measurement of Iridium in the Fullerene-Rich Layer in Central Japan by the Neutron Activation Method

Measurement has been made of Ir content in samples collected from lower Triassic layer in Gifu, central Japan, rich in fullerenes, in order to investigate if they are correlated with extraterrestrial events. The coincidence gamma ray measurement method has been applied to the samples after they had been activated by a research reactor at Japan Atomic Energy Research Institute and had been cooled for 2 months. The samples analyzed yielded Ir content at several ppt's, far less than those of the K/T boundary layers, for which Ir content of a few ppb's has been obtained. In view of other experiments that yielded negative results, it is concluded that the fullerenes are not to be taken as evidence of extraterrestrial events.

广西宁明下二叠统礁古油藏储层及成藏机理

广西宁明亭亮下二叠统茅口期生物礁为一已破坏的大型古礁油藏之一.论文对礁储层成因、三史关系(包括埋藏-构造史、有机质演化史和孔隙演化史)及成藏机理进行了深入的探讨.研究表明,礁原生孔隙普遍发育,但由于成岩期多世代方解石的胶结、充填和埋藏压实作用而破坏殆尽,其最终礁储层和有效孔隙的形成主要受控于深埋有机溶蚀作用及礁顶部存在的不整合面和古风化壳岩溶带.同时,紧邻生物礁南部的生油坳陷提供的丰富油源和地下有机酸性流体多期次地运移至礁储集体并在礁古岩溶带的基础上再次进行深埋有机溶蚀作用,为油气储集有效孔隙带的形成和油气运聚提供了最适时、最有效的条件和场所.结合礁顶部覆盖有连片分布的巨厚的三叠系泥质岩作区域盖层、礁油气藏即可形成.     

Morphometric differentiation and gene flow in emerald shiners (Notropis atherinoides) from the lower Great Lakes and the Niagara River

Differences in habitat (e.g., water velocity, prey, and predator regimes) are a driving force causing adaptive divergence among fish populations. This study used geometric shape analysis to assess morphological differences among emerald shiner (Notropis atherinoides) populations inhabiting the Niagara River, Lake Erie, and Lake Ontario. It was expected that emerald shiners inhabiting the two lakes would have more robust bodies and smaller heads, while river emerald shiners were expected to display more fusiform bodies with larger heads. The results of this study indicate that emerald shiners from Lake Erie and the Niagara River had a more robust form on average than individuals from Lake Ontario. Specifically, emerald shiners collected from Lake Ontario displayed more streamlined bodies and larger heads than emerald shiners collected from Lake Erie and the Niagara River. In addition, this divergence in body shape has apparently occurred despite the lack of distinct genetic differentiation as measured with microsatellite variation. Our results suggest that differences in water velocity alone may not be responsible for phenotypic variation in body shape among these emerald shiner populations, and other factors such as differences in prey or predator regimes are likely involved.
