深层致密砂岩储层非均质性强、分布规律复杂,地质甜点预测难度大。为实现高效勘探开发,如何准确识别与预测井间储层成岩相亟需深入研究。综合利用岩心、测井和三维地震资料,在准噶尔盆地永进油田侏罗系超深层储层成岩作用研究基础上,开展了成岩相识别及分布预测研究,认为储层成岩作用类型主要有压实作用、胶结作用及溶蚀与交代作用,可划分为强溶蚀+绿泥石包壳、中等溶蚀+自生高岭石、中等钙质胶结溶蚀、强钙质胶结及压实致密等5种成岩相。基于测井资料,利用岩石物理参数、物性参数对储层成岩相类型进行了综合识别,确定其垂向分布规律。研究发现强溶蚀+绿泥石包壳和中等溶蚀+自生高岭石这两种优势成岩相主要位于三角洲主干分流河道砂体内部,储层物性较好,是油层发育的主要部位。基于成岩相与地震纵波阻抗的对应关系分析,发现优势成岩相纵波阻抗相对较低,可通过纵波阻抗的数值分布特征预测优势成岩相分布。因此利用三维地震纵波阻抗反演成果开展了成岩相分布预测,根据纵波阻抗与不同类型成岩相对应关系落实了优势成岩相发育区。结果表明,优势成岩相主要位于研究区东北部的Y301—Y302井区以及西北部Y1井区,呈局部连片分布发育。储层成岩相识别可以为超深层地质甜点的分布预测研究提供重要依据。

A comparative analysis of the geochemical characteristics of sediments from the Oligocene Zhuhai Formation(32-23.8 Ma),the Miocene Zhujiang Formation(23.8-16.5 Ma),and the Hanjiang Formation(16.5—10.5 Ma) and a comprehensive analysis of the geochemical characteristics of rocks surrounding the paleo-Pearl River drainage contribute to understanding the influences of the Tibetan Plateau uplift on provenance evolution of the paleo-Pearl *** results show that the geochemical characteristics of sediments from the Oligocene Zhuhai Formation are very different from the geochemical characteristics of sediments from the Miocene Zhujiang and Hanjiang *** ∑ rare earth elements(REE) of mudstone is relatively high in the Zhuhai Formation,204.07-293.88 ppm(average 240.46 ppm),and low in the Zhujiang and Hanjiang Formations,181.32-236.73 ppm(average 203.83 ppm) and 166.84-236.65 ppm(average199.04 ppm),*** chemical index of alteration(CIA) for these samples has a similar trend to the∑ REE:the CIA of the Zhuhai Formation is relatively high and the CIA of the Zhujiang and Hanjiang Formations is relatively *** uplift of the Tibetan Plateau is crucial to the westward expansion of the paleo-Pearl River drainage.

沉积物的元素地球化学信息可以很好地反映沉积物源区、古气候古环境等信息,并且沉积物粒度和元素地球化学信息也有密切联系。为了进一步探讨干旱背景下沙溪庙组不同河道砂体成因以及沉积物粒度和沉积相与元素地球化学之间的关系,对川西地区盐浅1井的沉积相特征、元素地球化学特征进行系统的分析。结果表明:①盐浅1井沙溪庙组以红褐色泥岩和灰色砂砾岩为主,发育一套河漫平原沉积,可划分为大型河道、小型河道、决口水道、河漫滩及河漫湖泊5种岩石相组合;②不同岩石相组合的元素地球化学特征具有明显差异,大型河道表现出“Fe含量低,SiO_(2)含量高”的特点;而决口水道和小型河道SiO_(2)含量略低;河漫湖泊呈现出“Fe含量高,SiO_(2)含量低”的特点;而河漫滩呈现出“Fe含量较高,SiO_(2)含量高”的特点。岩石相组合整体表现为,SiO_(2)含量越高,粒度越大;且决口水道、小型河道以及河漫滩多发育于相对湿润的气候环境。③结合Al_(2)O_(3)/TiO_(2)、Cr/Zr和TiO_(2)/Zr等元素及比值综合判断,盐浅1井沙溪庙组离物源区近,母岩主要为长英质岩,构造背景主要为大陆岛弧背景。④根据Mg/Ca、Fe/Mn、Sr/Ba、m、V/(V+Ni)和Cu/Zn等元素及比值判断,沙溪庙组沉积期水体环境主要为陆地淡水环境,从下沙溪庙组至上沙溪庙组表现为2个由氧化—还原环境的变化过程,而气候变化更为频繁,气候出现多次由湿润—干旱的变化过程,但整体上从下沙溪庙组至上沙溪庙组气候更加干旱。研究为恢复川西坳陷沙溪庙组沉积环境,进一步探讨不同岩石相组合的形成规律以及有利储层砂体分布提供了依据。

TiO2 nanoflakes were prepared by hydrothermal precipitation method using Ti（SO4）2 as titanium source and NaOH solution as alkaline medium. Their surface morphology, grain size measured after high temperature calci- nation and effect on the electrochemical performance of Li ion battery were discussed. TiO2 nanoflakes were charac- terizated by means of transmission electron microscopy（TEM）, X-ray powder diffraction（XRD）, N2 adsorp- tion-desorption isothermal assay, cyclic voltammetry（CV） and cycle performance test. The result of electrochemical performance test shows that the prepared TiO2 nanoflakes have high discharge specific capacity and good cycle per- formance. Discharge specific capacity for the first circle at the discharge rate of 0.1 C is 261.5 mA·h·g-1. After 90 cycles, the discharge capacity reduces to 172.2 mA·h·g-1.

Homolog and congener profiles of polychlori- nated biphenyls （PCBs）, polychlorinated dibenzo-p- dioxins （PCDDs） and polychlorinated dibenzofurans （PCDFs） in commercial PCBs formulations are useful information for the source appointment of PCBs contam- ination as well as the risk assessment caused by potential exposure. Dielectric oil （ASKAREL Nr 1740） in an imported transformer found in China was sampled and analyzed by isotope dilution technology using high resolution gas chromatography-high resolution mass spectrometry （HRGC/HRMS）. The detailed homolog and congener profiles of PCBs obtained were compared with those of known Aroclor formulations. High similarity in the homolog profile between the oil sample and Aroclor 1260was found, with the hexachlorinated and hepta- chlorinated biphenyls accounting for more than 80.2% of the total PCBs concentration. Severn indicator PCBs contribute about 30%, while 12 PCB congeners （i.e., # 153, #143, #168, #180, #149, #165, #138, #170, #190, #187, #174, #181） account for more than 50% of the total PCB concentrations. Total concentration ofPCDDs, PCDFs and dioxin-like PCBs （DL-PCBs） was found to be 740 ng TEQ/g, of which 620 ng TEQ/g came from DL-PCBs. The contribution of PCDDs to the total TEQ was neglectable. The concentration of PCDFs homologs follows the order of OCDF 〉 HxCDFs 〉 HpCDFs 〉 PeCDFs 〉 TeCDFs, which is in consistence with the previous study on Aroclor 1260. Three DL-PCBs congeners （i.e., #118, #156, #157） accounted for 77% of the total concentration of DL-PCBs, also they contribute 72% in the TEQ caused by DL-PCBs.
