引用

Acta Geologica Sinica(English Edition) 2019年第1期93卷 146-154页

作者： SHAN Xuanlong du shang GUO Xufei College of Earth Sciences Jilin University

The presence of shale oil in the Cretaceous Hengtongshan Formation in the Tonghua Basin, drilled by the well TD-01, has been discussed in this geological investigation for the first time. To evaluate the high-quality source rocks of Cretaceous continental shale oil, the distribution characteristics and the evolution of the ancient environment, samples of shale were systematically analyzed in terms of sedimentary facies, organic geochemistry, and organic carbon isotopic composition. The results demonstrate that a TOC value of 1.5% represents the lower-limit TOC value of the high-quality source rocks. Source rocks have an aggregate thickness of 211 m and contain abundant organic matter, with TOC values of 2.69% on average and a maximum value over 5.44%. The original hydrocarbon-generative potential value(S_1+S_2) is between 0.18 mg/g and 6.13 mg/g, and the Ro is between 0.97% and 1.40%. The thermal maturation of the source rocks is relatively mature to highly mature. The δ^(13)C value range is between -34.75‰ and -26.53‰. The ratio of saturated hydrocarbons to aromatic hydrocarbons is 1.55 to 5.24, with an average of 2.85, which is greater than 1.6. The organic types are mainly type Ⅱ_1, followed by type Ⅰ. The organic carbon source was C_3 plants and hydrophytes. The paleoclimate of the Hengtongshan Formation can be characterized as hot and dry to humid, and these conditions were conducive to the development of high-quality source rocks. A favorable paleoenvironment and abundant organic carbon sources provide a solid hydrocarbon generation base for the formation and accumulation of oil and gas in the shale of the Tonghua Basin.

Effects of Pesticide Applications on the Biochemical Properties of Transgenic cry 2A Rice and the Life History Parameters of Nilaparvata lugens Stl (Homptera: Delphacidae)

引用

Journal of Integrative Agriculture 2013年第9期12卷 1606-1613页

作者： SHI Zhao-peng du shang-gen YANG Guo-qing LU Zhen-zhen WU Jin-cai Horticulture and Plant Protection College Yangzhou University

Effects of transgenic Bt rice on non-target pests following pesticide applications plays an important role in evaluating the ecological safety of transgenic rice. Changes of the life history parameters of laboratory population of Nilaparvata lugens feeding on transgenic Bt rice T2A-1 and its parental line cv. MH63 as the control, and the contents of oxalic acid and soluble sugar following three pesticides （triazophos, jinggangmycin and chlorantraniliprole） treatments were investigated in this paper. Results showed that the population parameters of N. lugens and the physiological and biochemical parameters of rice did not differ significantly between T2A-1 and MH63 without pesticide application. But, the emergence rate （ER）, the nymphal number of next generation （NN）, and the index of population trend （IP） on T2A-1 treated with 10 mg L^-1 of triazophos were significantly higher than those on MH63, respectively, while the hatchability （HB） on T2A-1 treated with the three pesticides were obviously lower than those on MH 63. Furthermore, the content of oxalic acid in MH63 treated with 20 mg L-1 triazophos and, 40 and 80 mg L-1 chlorantraniliprole was significantly higher than that in T2A-1, while the content of soluble sugar in T2A-1 treated with 400 mg L-1 jinggangmycin was significantly higher than that in MH63. The results above indicated that triazophos in a low dose could cause a more favor of T2A-1 to population growth of N. lugens compared with MH 63.

引用

Global Geology 2018年第1期21卷 26-35页

作者： GUO Xufei SHAN Xuanlong du shang College of Earth Sciences Jilin University

The Gulf of Suez Basin is a very mature and extremely prospective petroleum province. Many heavy oil fields have been found in the Basin,and such reserves are abundant. Characteristics and models of heavy oil are analyzed in this study based on tectonic,basin evolution,stratigraphic distribution and geochemical *** best reservoirs of heavy oil are Miocene sandstone and limestone formations. Source rocks of hydrocarbon include deep limestone and shale of the Brown Limestone,the Thebes Formation and the Rudeis *** evaporite rocks with rock salts and anhydrites deposited broadly throughout the basin are the most important regional seals,whereas Miocene shales are intraformational and regional seals that cover small areas. Heavy oil could be directly generated or densified during vertical migration along faults and reservoir *** heavy oil accumulation model is a mixed model that includes three mechanisms: fault dispersal,sulfocompound reactions and hydrocarbons generated from immature source rock. After analyzing the model and the distribution of source rocks,reservoirs,heavy oil fields and structures,it is concluded that the potential heavy oil area is at the center of the basin.

引用

Journal of Environmental Science and Engineering(B) 2014年第2期3卷 79-86页

作者： Jing Ye Zhihao Qiu Yuping du Aihua shang Department of Chemical and Environmental Engineering Shanghai Institute of Technology Shanghai 201418 China

Pesticides will be released into aquatic systems after application in agriculture or industry. AOPPs （aryloxyphenoxypropanoic acids） herbicides, including fenoxaprop, quizalofop-P-ethyl and haloxyfop-methyl, can pose aquatic toxicity on cyanobacterium M. aeruginosa （Microcystis aeruginosa）. The inhibition percentages of the biomass of M. aeruginosa exposure to 10 mg＇L-I fenoxaprop, quizalofop-P-ethyl and haloxyfop-methyl on day 7 were 23.13%, 7.55%, and 7.56%, respectively. Protein content was also inhibited by the three AOPPs to fenoxaprop is the most toxic, followed by quizalofop-P-ethyl varying degrees. The growth and protein content results showed that and haloxyfop-methyl. It indicates that both the biomass and the protein content can be served as an indicator for evaluating the toxicity of the three chemicals. Growth rates of M. aeruginosa exposure to fenoxaprop are also the most significantly different compared to the control, which means that fenoxaprop is the most toxic among the three compounds. Results from this study may provide insights for evaluation of environmental risks of AOPPs. In addition, such insights will be helpful for guiding the application of AOPPs in agriculture.

Accumulation conditions of outside source heavy oil in NepaBotuoba Sub-basin,Russia and prediction of distribution

引用

Global Geology 2016年第3期19卷 125-132页

作者： XU Jianhua SHAN Xuanlong du shang HE Wentong LIANG Ye College of Earth Sciences Jilin University

In terms of tectonic evolution and petroleum geological conditions of the Nepa-Botuoba Sub-basin and its adjacent su4b-basins,the accumulation conditions of the heavy oil were analyzed. The studied area had plenty of oil and gas accumulation,but there were no developed source rocks. It is a typical outside source accumulation,whose origins from thick high-quality source rock deposited in the adjacent sub-basins. The shallow layer has favorable heavy oil reservoir conditions and poor sealing conditions,which benefits the thickening of hydrocarbon. The multi-periods of structural compression not only uplifted the studied area drastically,but also created a series of fault zones and large-scale slope belt. The structural compression also provided channel and sufficient power for migration of hydrocarbon to shallow layers. Based on these conditions,the favorable accumulation zone of heavy oil was predicted,which provided direction for heavy oil exploration in Nepa-Botuoba Subbasin.

引用

Chinese Medical Journal 2015年第13期128卷 1787-1792页

作者： Xiao-Long du Ling-shang Kong Qing-You Meng Aimin Qian Wen-Dong Li Hong Chen Xiao-Qiang Li Cheng-Long Li Department of Vascular Surgery The Second Affiliated Hospital of Soochow University Suzhou 215000 Jiangsu China

Background： Catheter-directed thrombolysis （CDT） has been a mainstay in treating deep venous thrombosis （DVT）. However, the optimal dosage ofa thrombolytic agent is still controversial. The goal of this study was to evaluate the safety and efficacy of low dosage urokinase with CDT for DVT. Methods： A retrospective analysis was perfornaed using data from a total of 427 patients with DVT treated with CDT in our single center between July 2009 and December 2012. Early efficacy of thrombolysis was assessed with a thrombus score based on daily venography. The therapeutic safety was evahmted by adverse events. A venography or duplex ultrasound was performed to assess the outcome at 6 months, 1 year and 2 years postoperatively. Results： The mean total dose of 3.34 （standard deviation [SD] 1.38） million units of urokinase was administered during a mean of 5.18 （SD 2.28） days. Prior to discharge, Grade Ⅲ （complete lysis） was achieved in 154 （36%） patients; Grade II （50-99% lysis） in 222 （52%）： and Grade I （50%~ lysis） in 51 （12%）. The major complications included one intracranial hemorrhage, one henaatochezia, five gross hematuria, and one pulmonary embolism. Moreover, no death occurred in the study. Conclusions： Treatment of low-dose catheter-directed thrombosis is an efficacious and safe therapeutic approach in patients with DVT offering good long-term outcomes and minimal complications.
