Dynamic simulation of gas hydrate reservoirs in the Shenhu area,the northern South China Sea

为进一步了解南海北部神狐海域天然气水合物的成藏匹配条件,利用典型二维地震剖面,构建了该区的地质模型,并对其进行了天然气水合物成藏动力学的模拟。研究结果表明:神狐海域具备天然气水合物成藏的温度、压力条件;生物气和热解气的资源潜力巨大,满足水合物形成的气源条件;运移条件优越,有利于天然气水合物的聚集成藏。并提出了该区天然气水合物的成藏模式。The north slope of the South China Sea is structurally characterized by a passive continental margin and has various Cenozoic oil-and gas-bearing depositional basins,where hydrocarbon resources are abundant,and the geological and tectonic settings,the temperature and pressure regimes as well as the methane-generative potential of thick organic-rich sediments are all favorable for the formation of gas hydrate.As a result,this region is also an ideal area for studying gas hydrate accumulations.In order to understand natural conditions of the gas hydrate formation,based on the typical 2-dimensional seismic image of the Shenhu area,a geological model of gas hydrate reservoirs was established and a dynamic simulation of gas hydrate accumulations was carried out as well.The results indicated that the temperature and pressure of the Shenhu area are appropriate for gas hydrate accumulations,source rocks there have a huge gas-generative potential and hydrocarbon migration conditions are favorable,providing an abundant gas source and good pathways for the gas hydrate formation.A forecasting model of the gas hydrate formation was given based on basin analysis,indicating that the Shenhu area is a better prospect area of gas hydrate because of its huge potential of gas hydrate resources.国土资源部公益性行业科研专项(200811014)“天然气水合物成藏的控制因素研究”;国家自然科学基金项目(No.40930845)“南海北部深水盆地油气渗漏系统与天然气水合物富集机制研究”;国家重点基础研究发展规划(973)项目(2009CB219501)“南海北部天然气水合物成藏的气源条件研究”联合资

人乳头瘤病毒16型病毒样颗粒的制备及其免疫原性研究

利用PCR技术从HPV16阳性阴道分泌物标本中获得HPV16 L1基因片段,并将其插入表达载体pTO-T7中,构建重组表达质粒pTO-T7-HPV16-L1;以该重组质粒转化大肠杆菌ER2566并表达HPV16 L1蛋白;所表达的HPV16 L1蛋白经过硫酸铵沉淀、离子交换层析和疏水相互作用层析等纯化步骤后,HPV16 L1纯度达到98%以上,并可在体外装配为直径50nm的病毒样颗粒;动物免疫原性研究结果显示,该病毒样颗粒可诱导高滴度的针对HPV16的中和抗体。上述研究结果表明通过大肠杆菌表达系统制备的HPV16病毒样颗粒具有纯度高,与天然病毒颗粒形态高度相似的特点,并具有高度免疫原性,可以应用于HPV16病毒样颗粒的结构功能研究及HPV16疫苗研发等领域

钛基镍-钴氧化物电极在盐水电解中活性衰减原因的探讨

本文研究钛基镍-钴氧化物(Ti/Ni-Co-O)电极在电解盐水过程中的耐蚀性和进行析氧反应的稳定性,分析探讨了该电极性能衰减的原因.在300gdm~(-3)NaCl水溶液中,于电流密度200mA·cm~(-2)下电解数小时后,溶液经原子吸收分光光度法检测,证明存在镍、钴离子,其溶解速度大于文献中钌-钛阳极中钌的溶解速度,镍钴含量之比大于涂液中两成分之比.该电极在1MKOH 溶液进行析氧反应时具有长期的稳定性,在0.5M K_2SO_4溶液中也比钌-钛电极寿命长.实验结果说明镍-钴氧化物在酸性溶液中的化学不稳定性是其析氯或析氧活性衰减的根本原因,针对钌-钛阳极设计的析氧反应标准快速寿命检测不适于评价钛基镍-钴氧化物电极

Catalytic Recombination Characteristics of Atomic Oxygen on Material Surface by Optical Emission Spectroscopy

Catalytic recombination of atomic oxygen, the main species of air ionization, on heat shield material surfaces was studied in a microwave plasma flow reactor. The atomic oxygen concentration profile above material samples was nonintrusive measured by optical emission spectroscopy. The catalytic recombination coefficients on material surfaces were deduced by the diffusion equation. The catalytic recombination coefficients for the heat shield materials at high temperature obtained in the present experiment are very important parameters for thermal shield design of space vehicles
