| 1 | Progress in Global Gas Hydrate Development and Production as a New Energy Resource显示文摘Natural gas hydrates have been hailed as a new and promising unconventional alternative energy,especially as fossil fuels approach depletion,energy consumption soars,and fossil fuel prices rise,owing to their extensive distribution,abundance,and high fuel efficiency.Gas hydrate reservoirs are similar to a storage cupboard in the global carbon cycle,containing most of the world's methane and accounting for a third of Earth's mobile organic carbon.We investigated gas hydrate stability zone burial depths from the viewpoint of conditions associated with stable existence of gas hydrates,such as temperature,pressure,and heat flow,based on related data collected by the global drilling programs.Hydrate-related areas are estimated using various biological,geochemical and geophysical tools.Based on a series of previous investigations,we cover the history and status of gas hydrate exploration in the USA,Japan,South Korea,India,Germany,the polar areas,and China.Then,we review the current techniques for hydrate exploration in a global scale.Additionally,we briefly review existing techniques for recovering methane from gas hydrates,including thermal stimulation,depressurization,chemical injection,and CH4-CO2 exchange,as well as corresponding global field trials in Russia,Japan,United States,Canada and China.In particular,unlike diagenetic gas hydrates in coarse sandy sediments in Japan and gravel sediments in the United States and Canada,most gas hydrates in the northem South China Sea are non-diagenetic and exist in fine-grained sediments with a vein-like morphology.Therefore,especially in terms of the offshore production test in gas hydrate reservoirs in the Shenhu area in the north slope of the South China Sea,Chinese scientists have proposed two unprecedented techniques that have been verified during the field trials:solid fluidization and formation fluid extraction.Herein,we introduce the two production techniques,as well as the so-called'fbur-in-one'environmental monitoring system employed during the Shenhu production test.Methane is not currently commercially produced from gas hydrates anywhere in the world;therefore,the objective of field trials is to prove whether existing techniques could be applied as feasible and economic production methods for gas hydrates in deep-water sediments and permafrost zones.Before achieving commercial methane recovery from gas hydrates,it should be necessary to measure the geologic properties of gas hydrate reservoirs to optimize and improve existing production techniques.Herein,we propose horizontal wells,multilateral wells,and cluster wells improved by the vertical and in dividual wells applied during existing field trials.It is noteworthy that relatively pure gas hydrates occur in seafloor mounds,within near-surface sediments,and in gas migration conduits.Their extensive distribution,high saturation,and easy access mean that these types of gas hydrate may attract considerable attention from academia and industry in the future.Herein,we also review the occurrence and development of concentrated shallow hydrate accumulations and briefly introduce exploration and production techniques.In the closing section,we discuss future research needs,key issues,and major challenges related to gas hydrate exploration and production.We believe this review article provides insight on past,present,and future gas hydrate exploration and production to provide guidelines and stimulate new work into the field of gas hydrates. | LIU Liping SUN Zhilei ZHANG Lei WU Nengyou Yichao Qin JIANG Zuzhou GENG Wei CAO Hong ZHANG Xilin ZHAI Bin XU Cuiling SHEN Zhicong JIA Yonggang | 2019 | Acta Geologica Sinica(English Edition)2019，93，3： | 13 |

| 6 | 3DRGO-NiFe2O4/NiO nanoparticles for fast and simple detection of organophosphorus pesticides显示文摘The residues of organophosphorus pesticide(OPs)on fruits and vegetables pose a threat to human health,so it is very meaningful to explore simple and fast detect methods for OPs residual.In this work,nickel ferrite/nickel oxide nanoparticles co-loaded three-dimensional reduced graphene oxide(3DRGONiFe2O4/NiO NPs),as a new low cost nanocomposite,was prepared.Based on its high performance mimetic peroxidase activity,a colorimetric method for the detection of OPs has been developed.Dichlorvos was chosen as model compounds to evaluate the detection performance.The detection linear range for dichlorvos is from 50μg/mL to 2.5×10^4μg/mL with a detection limit of 10μg/mL.Furthermore,a test paper can be developed based on the 3 DRGO-NiFe2O4/NiO NPs for visual detection of dichlorvos,and the image information of the paper sensor can be converted into digital signal and quantitative detection by a smartphone.Notably,this method can also be used to detect dichlorvos in real samples,including vegetables and fruits.Thus,the developed naked assay holds great potential in simple,inexpensive and rapid detection of OPs in fruit and vegetable samples. | Zhenni Wei Huiqing Li Jing Wu Yalei Dong Hongyi Zhang Hongli Chen Cuiling Ren | 2020 | Chinese Chemical Letters2020，31，1： | 1 |

| 14 | Research Progress of Seafloor Pockmarks in Spatio-Temporal Distribution and Classification显示文摘Seafloor pockmarks are important indicators of submarine methane seepages and slope instabilities.In order to promote the understanding of submarine pockmarks and their relationship with sediment instabilities and climate changes,here we summarize the research results of pockmarks in the spatio-temporal distributions and shaping factors.Most of pockmarks occur along active or passive continental margins during the last 25 kyr B.P..Circular and ellipse are the most common forms of pockmarks,whereas pockmarks in a special crescent or elongated shape are indicators of slope instabilities,and ring-shape pockmarks are endemic to the gas hydrate zones.Further researches should be focused on the trigger mechanism of climate changes based on the pockmarks in the high latitudes formed during the deglaciation periods,and the role of gas hydrates in the seafloor evolution should be elucidated.In addition,the feature of pockmarks at their early stage(e.g.,developing gas chimneys and gas driving sedimentary doming)and the relations between pockmarks and mass movements,mud diapirs could be further studied to clarify the influences of rapid methane release from submarine sediments on the atmospheric carbon contents. | XU Cuiling XU Guoqiang XING Junhui SUN Zhilei WU Nengyou | 2020 | Journal of Ocean University of China2020，19，1： | 1 |
