Electrochemical reduction of CO_(2)to syngas(CO and H_(2))offers an efficient way to mitigate carbon emissions and store intermittent renewable energy in ***,the hierarchical one‐dimensional/three‐dimensional nitrogen‐doped porous carbon(1D/3D NPC)is prepared by carbonizing the composite of Zn‐MOF‐74 crystals in situ grown on a commercial melamine sponge(MS),for electrochemical CO_(2)reduction reaction(CO_(2)RR).The 1D/3D NPC exhibits a high CO/H_(2)ratio(5.06)and CO yield(31 mmol g^(−1)h^(−1))at−0.55 V,which are 13.7 times and 21.4 times those of 1D porous carbon(derived from Zn‐MOF‐74)and N‐doped carbon(carbonized by MS),*** is attributed to the unique spatial environment of 1D/3D NPC,which increases the adsorption capacity of CO_(2)and promotes electron transfer from the 3D N‐doped carbon framework to 1D carbon,improving the reaction kinetics of CO_(2)*** results and charge density difference plots indicate that the active site of CO_(2)RR is the positively charged carbon atom adjacent to graphitic N on 1D carbon and the active site of HER is the pyridinic N on 1D *** presence of pyridinic N and pyrrolic N reduces the number of electron transfer,decreasing the reaction kinetics and the activity of CO_(2)*** CO/H_(2)ratio is related to the distribution of N species and the specific surface area,which are determined by the degree of spatial confinement *** CO/H_(2)ratios can be regulated by adjusting the carbonization temperature to adjust the degree of spatial confinement *** the low cost of feedstock and easy strategy,1D/3D NPC catalysts have great potential for industrial application.

Acta Geologica Sinica(English Edition) 1997年第2期71卷 217-226页

作者： Li Rufeng liu Benpei and Zhao chenglin University of Petroleum, Beijing China University of Geosciences, Beijing University of Petroleum, Beijing

In light of the principle of sequence stratigraphy, detailed analysis of depositionalsequences and systematical carbon isotope measurements were done for the Triticites zone ofthe typical Late Carboniferous section in the Dushan area of southern Guizhou. Two sequencesand seventeen parasequences, which can be correlated with the two sequences and seventeensubsequences in the North American Midcontinent, are distinguished in the Gzhelian, whichprovides convincing evidence of the global synchroneity of the depositional records. The inter-nal relations between carbon isotope evolution and eustasy were studied and the evolutionarycharacteristics of carbon isotopes in depositional sequences have been summarized.

通过搜集显生宙以来不同地质时期内海相碳酸盐岩鲕粒及胶结物矿物成分、钾盐矿床矿物种类及组合特征、蒸发岩盆地中石盐流体包裹体成分,并利用这些资料与人工海水模拟实验得到的石盐中Br分配特征的对比,得出海水成分在5.5亿年以来的显生宙期间,经历了五个阶段:其中晚元古代至寒武纪早期、二叠纪早期至中生代早期、新生代早期至现今,这些时期的原始海水组成特征系数m(SO_4^(2-))+m(HCO_3^-)/2>m(Ca^(2+)),为Na-Mg-K-SO_4-Cl型海水,此期间沉积的钾盐矿床的钾镁盐矿物主要为钾盐镁矾、无水钾镁矾、杂卤石、硫酸镁石等含MgSO_4矿物,海相鲕粒和碳酸盐胶结物矿物成分为文石;而寒武纪早期至石炭纪、中生代早期至新生代早期,原始海水组成特征系数m(Ca^(2+))>m(SO_4^(2-))+m(HCO_3^-)/2<,为Na-Mg-KCa-Cl型海水,此期间沉积的钾镁盐矿物主要为光卤石和钾石盐,甚至含有溢晶石,海相鲕粒和碳酸盐胶结物矿物成分为方解石。根据石盐流体包裹体成分计算得出:显生宙期间,海水K+含量大部分时间变化幅度较小,为9.3～11.5mmol/kg H_2O(除了石炭纪和晚元古代),平均为10.55mmol/kg H_2O。Mg^(2+)含量在早寒武世≥67mmol/kg H_2O、晚志留世至中泥盆世31～41mmol/kg H_2O、晚古生代≥48mmol/kg H22O、晚白垩世34mmol/kg H_2O和现代55.1mmol/kg H_2O。Ca^+含量在晚元古代至古生代早期≤11mmol/kg H_2O、古生代早期至石炭纪22～35mmol/kg H_2O、石炭纪至中生代早期≤17mmol/kg H_2O、中生代早期至新生代早期19～39mmol/kg H_2O及新生代早期至今7～21mmol/kg H_2O。SO_4^(2-)含量在晚元古代至古生代早期≥23mmol/kg H_2O、古生代早期至石炭纪5～17mmol/kg H_2O、石炭纪至中生代早期13～22mmol/kg H_2O、中生代早期至新生代早期5～19mmol/kg H_2O及新生代早期至今12～29.2mmol/kg H_2O。海水Ca^(2+)与SO_4^(2-)含量的相对变化是控制海相钾盐矿床钾镁盐矿物类型的基本因素。同时,利用以上数据计算得到的显生宙各时期海水[m(Mg^(2+))+m(SO_4^(2-))]/[m(K^+)+m(Ca^(2+))]的变化与各时期海相蒸发岩系石盐层底部的Br含量变化具有同步性,进一步验证了显生宙期间海水成分是不断变化的,是约束海相蒸发岩钾盐矿物类型的主要因素。海水成分变化的控制因素为洋中脊热液和陆地水,其中洋中脊热液起主要作用,而控制这些因素变化的根本原因为板块构造运动。

Occurrence Models of Movable Fluid in Lacustrine Sandstone Reservoir of Chang 7 Member in the Heshui Block， Ordos Basin， China

引用

Journal of Earth Science 2021年

作者： Qibiao Zang chenglin liu Rizwan Sarwar Awan Xiya Yang Zhendong Lu Guoxiong Li Yuping Wu Dehao Feng State Key Laboratory of Petroleum Resource and Prospecting， China University of Petroleum College of Geosciences， China University of Petroleum

The Chang 7 sandstone is characterized by complex micro-pore structures， strong heterogeneity， and differential fluid distribution. These characteristics result in low oil recovery. In this paper， various techniques， including high-pressure mercury intrusion， nuclear magnetic resonance， scanning electron microscope， thin section， and X-ray diffraction， are employed to quantitatively evaluate the occurrence characteristics and influencing factors of movable fluids in Chang 7 sandstone reservoirs from the Heshui Block with different fractal structures. Results show that the dominant sandstone type is feldspar lithic fragment sandstone. Chang 7 reservoir has been divided into three types (types I， Ⅱ， and Ⅲ) based on capillary pressure curves and pore structure parameters. These reservoirs are characterized by various fractal structures and different movable fluids distribution. Multiple possible factors affecting the movable fluid distribution are analyzed， including physical properties， pore structure， pore size distribution， mineral content， and heterogeneity. Movable fluid saturation is positively correlated with physical properties， weighted average pore-throat radius， median pore-throat radius， final residual mercury saturation， and maximum mercury withdrawal saturation. In contrast， it is negatively correlated with displacement pressure and has no obvious correlation with the sorting coefficient. Micron- and submicron-scale pores are beneficial to the movable fluid occurrence， while nano-scale pores are vice versa. The influence of mineral content on movable fluid occurrence varies with mineral types. Quartz is conducive to the movable fluid occurrence in submicron-scale pores， while carbonate cementation inhibits the movable fluid occurrence in submicron-scale pores. The inhibition of clay on the movable fluid occurrence is mainly reflected in submicron- and nano-scale pores and varies with clay mineral types. The influence of heterogeneity on the movable fluid

基于角度散斑相关原理开展了对喷砂表面粗糙度样块的粗糙度测量实验研究。通过对散斑图像数据的处理和分析,提出了求取角度散斑相关系数最大值的滑动相关算法。该算法能有效克服表面不平度、波度等因素的不利影响。从最佳测量条件出发,提出了最佳入射角增量的概念,并在此基础上形成了包括散斑图像采集过程和图像数据处理方法在内的一整套表面粗糙度测量方法。该测量方法的核心是对被测表面的多个激光照明区域和多个激光入射角下的远场散斑图像的采集及数据处理。实验结果表明,应用本测量方法得到的轮廓均方根偏差最佳估计值σ_p与表面样品给定的轮廓算术平均偏差R_a成很好的线性关系。

鄂尔多斯盆地具备富氦天然气地质条件,氦气资源潜力大,但对黄龙天然气田(以下简称黄龙气田)氦气地质条件、成藏过程和机制缺乏深入分析。基于文献调研、岩心录井、测井分析、天然气组分和同位素测试,评价了黄龙气田地质条件并建立了氦气成藏模式。结果表明:黄龙气田氦气含量整体呈现南高北低,南部氦气含量峰值为0.226%,北部氦气含量峰值为0.168%,氦气含量向东逐渐降低,向西降低较快;区内存在结晶变质基底和高铀钍元素丰度的泥岩层、铝土岩层,推测为潜在氦源岩层;基底断裂与分布广泛的逆断层及构造裂缝为氦气运移优势通道;丰富的地层水和孔隙水为氦气运移提供了载体;发育有泥岩、泥质碳酸盐岩、泥质硬石膏等封闭性良好的盖层,还存在具有高剩余压力的区域性盖层;氦气成藏模式为地下水脱氦聚集。
