1四川盆地金秋区块非常规天然气工厂化井作业设想显示文摘四川盆地上三叠统须家河组气藏经历了50多年的勘探开发,存在着'储量大、采出低'的难题。工厂化井作业是降低钻完井、井场建设成本,提高作业效率的重要手段。为此,基于北美地区工厂化钻完井作业成功实施的案例,综合分析了四川盆地金秋区块须家河组非常规天然气资源的特点,提出了以下工厂化井作业模式:①采用小井眼结构及单井场最多布36口井,井间地下间距650m的井眼数量优选方案;②采用单排、多井丛且有备用井眼(井丛)的丛式井布局模式;③采用3项交叉作业(钻井+完井+生产)模式,缩短井交付周期;④柔性井场布局设计可以有效地避开地形的限制;⑤选用定制钻机和修井机来完成特定作业目的;⑥作业过程中合理设计离线作业以提高钻完井效率;⑦采用批量完井压裂工厂化模式。这种工厂化井作业可为非常规天然气资源高效、低成本开发提供技术思路和实现手段。李鹴 Hii King-Kai Todd Franks 谢明华 2013天然气工业2013,33,6:18
2基于生物可给性的某冶炼厂土壤重金属健康风险评价显示文摘为科学评价重金属污染场地的人体健康风险,以某冶炼厂土壤为研究对象,采用PBET(Physiologically-Based Extraction Test)和IVG(In-Vitro gastrointestinal)两种方法测定了As、Cd、Cu、Pb、Zn的生物可给性,并对比了只考虑重金属总量与基于生物可给性的人体健康风险.结果表明,场地土壤As、Cd、Pb的平均含量分别高达7063,691,3811mg/kg,严重超过国家环境质量标准.在PBET和IVG测试中,5种重金属的平均生物可给性介于1.81%~44.8%与1.78%~30.1%之间.As是PBET中生物可给性最高的重金属元素,而在IVG中Cd的生物可给性最高;含磷矿物的存在使Pb的生物可给性最低.提取液pH值及组成组分与重金属元素间的化学行为是造成两种方法结果差异的主要原因.在模型假设的条件下,土壤原有重金属的总危险商与总致癌系数为27.2与2.95×10^-3.考虑生物可给性使二者降低了59.9%~84.4%与55.6%~79.4%,且两个系数大小均呈现PBET胃液>PBET胃肠液>IVG胃液>IVG胃肠液的规律.调整后可以认为Pb不再具有健康风险,Cd仅具有致癌风险,只有As同时具有非致癌风险与致癌风险.尽管考虑重金属生物可给性后场地仍具有不可忽视的人体健康风险,但经过调整后能更准确地识别重金属的危害程度,避免场地的过度修复.冯康宏 范缙 Lik Ung Stanley Hii 罗启仕 曹心德 续晓云 2021中国环境科学2021,41,1:14
3High proportion strontium-doped micro-arc oxidation coatings enhance early osseointegration of titanium in osteoporosis by anti-oxidative stress pathway显示文摘The excessive accumulation of reactive oxygen species(ROS)under osteoporosis precipitates a microenvironment with high levels of oxidative stress(OS).This could significantly interfere with the bioactivity of conventional titanium implants,impeding their early osseointegration with bone.We have prepared a series of strontium(Sr)-doped titanium implants via micro-arc oxidation(MAO)to verify their efficacy and differences in osteoinduction capabilities under normal and osteoporotic(high OS levels)conditions.Apart from the chemical composition,all groups exhibited similar physicochemical properties(morphology,roughness,crystal structure,and wettability).Among the groups,the low Sr group(Sr25%)was more conducive to osteogenesis under normal conditions.In contrast,by increasing the catalase(CAT)/superoxide dismutase(SOD)activity and decreasing ROS levels,the high Sr-doped samples(Sr75% and Sr100%)were superior to Sr25% in inducing osteogenic differentiation of MC3T3-E1 cells and the M2 phenotype polarization of RAW264.7 cells,thus enhancing early osseointegration.Furthermore,the results of both in vitro cell co-culture and in vivo studies also showed that the high Sr-doped samples(especially Sr100%)had positive effects on osteoimmunomodulation under the OS microenvironment.Ultimately,the collated findings indicated that the high proportion Sr-doped MAO coatings were more favorable for osteoporosis patients in implant restorations.Xinkun Shen Kai Fang Kendrick Hii Ru Yie Zixin Zhou Yiding Shen Shuyi Wu Yue Zhu Zhennan Deng Pingping Ma Jianfeng Ma Jinsong Liu 2022Bioactive Materials2022,7,4:2
