| 1 | 锡石^(40)Ar/^(39)Ar法直接定年探讨显示文摘赣南漂塘钨矿共生白云母和锡石40Ar/39Ar定年对比研究,前者采用激光阶段加热分析,后者采用真空击碎法提取流体包裹体.白云母形成平坦的年龄谱,坪年龄为159.3±1.5Ma(2σ).锡石形成下降型年龄谱,最初6个阶段表观年龄明显偏老且迅速下降,从3954Ma降至196Ma,表明锡石中次生包裹体含有过剩氩;第7~18阶段形成了年龄坪,坪年龄为159.1±1.8Ma,对应的数据点构成高度线性相关的等时线,等时年龄为158.6±2.9Ma,代表了原生包裹体的年龄.锡石原生包裹体年龄与白云母年龄一致,代表了漂塘钨矿的形成年龄.研究结果表明锡石是40Ar/39Ar真空击碎分析理想的定年对象,其原生包裹体年龄代表了成矿年龄.继闪锌矿之后,再次拓展了流体包裹体40Ar/39Ar法应用于矿石矿物直接定年测试对象. | 白秀娟 王敏 卢克豪 方金龙 蒲志平 邱华宁 | 2011 | 科学通报2011,56,23: | 21 |
| 2 | Comparative study of gas accumulations in the Permian Changxing reefs and Triassic Feixianguan oolitic reservoirs between Longgang and Luojiazhai-Puguang in the Sichuan Basin显示文摘Reef and oolitic gas reservoirs in the Permian Changxing and Triassic Feixianguan formations have been discovered in both the Luojiazhai-Puguang and Longgang areas of the Sichuan Basin, but the accumulation scale, abundance and distribution patterns differ greatly. In fact, the two areas have more differences than they have similarities. Similarities include: (1) the lithology, properties and types of porosity of the reef and oolitic reservoirs are primarily consistent in the two areas; (2) well-developed regional caprocks that seal the fluid system; and (3) accumulation process histories, with liquid hydrocarbon charging at an early stage, cracking into gas at a high to over-mature stage, adjustment of gas reservoirs at an uplifting stage, and final reservoir generation at a late stage. Differences include: (1) gas accumulations in the Luojiazhai-Puguang area that are dominated by oil-type cracked gas, with multiple and sufficient gas sources, contrasting with gas accumulations in the Longgang area that are dominated by coal-sourced gas with insufficient gas sources; (2) heterogeneity and horizontal diversity of reservoirs in the Longgang area that are stronger than in the Luojiazhai-Puguang area; and (3) the development of deep and large faults in the Luojiazhai-Puguang area that link source, reservoir and migration pathways, contrasting with poorly developed faults in Longgang area, where laterally variable fractures are the major migration pathway. Because of these differences, abundant large-scale structurally-controlled gas accumulations are developed in the Luojiazhai-Puguang area, whereas lithology plays a more important role in gas accumulation in the Longgang area where accumulations are smaller-scale and have lower gas-bearing abundance. We suggest that future exploration for reef and oolitic gas accumulations should be strengthened in NE Sichuan and NW Sichuan Jiulongshan. In particular, the transitional zone between Longgang and Kaijiang-Liangping Bay has the best potential for new discoveries. | ZHAO WenZhi XU ChunChun WANG TongShan WANG HongJun WANG ZeCheng BIAN CongSheng LI Xia | 2011 | Chinese Science Bulletin2011,56,31: | 21 |
| 3 | 流体包裹体^(40)Ar/^(39)Ar定年技术与应用显示文摘同位素地质年代学的各种定年方法都有其特定的测定对象(矿物或全岩)和适用范围,致使许多金属矿床难以进行年龄测定.为解决此难题,建立了流体包裹体^(40)Ar/^(39)Ar定年方法,经过30年的探索发展和不断改进完善,已广泛应用于热液矿床、变质岩和石英脉的形成年龄测定,甚至成功应用于松辽盆地深层天然气成藏年龄研究.在详细介绍流体包裹体提取技术和气体纯化技术的基础上,着重总结我们团队运用流体包裹体^(40)Ar/^(39)Ar定年技术在热液矿床和天然气藏形成年龄研究方面取得的重要成果,以及气体混合线的概念及其年龄意义. | 邱华宁 白秀娟 | 2019 | 地球科学2019,44,3: | 14 |
| 4 | 如何实现油气成藏期的精确定年显示文摘随着油气田'精细勘探'的进一步发展,油气藏的精确定年日益成为一种必要。目前可实现油气藏精确定年的方法多依靠放射性同位素体系,如钾—氩、氩—氩和铼—锇等。按照所测定样品的不同,又分为成藏矿物定年、油气包裹体定年和储层有机质定年等。但在实际勘探工作中,受地质定年理论或实验方法学的影响,单一定年技术所提供的年代数据的准确度和精密度仍有所欠缺,在对地质事件的解释上也容易产生一些疑议。在如何实现油气成藏期精确定年这项命题上,不仅需要不断地提高和改进实验分析技术,还需要完善定年方法的基础地质理论,以实现对数据结果的合理解释。油气成藏年代学分析不能仅仅停留在单一的方法技术上,应从各油气藏的特点出发,寻找与油气成藏直接相关的产物,采用多技术手段,获得较全面的年代学信息。 | 王华建 张水昌 王晓梅 | 2013 | 天然气地球科学2013,24,2: | 11 |
| 5 | ^(40)Ar/^(39)Ar geochronology constraints on hydrocarbon accumulation and destruction periods in the Bankeng paleo-reservoir in the southern margin of the middle Yangtze block显示文摘The exact determination of isotopic ages of hydrocarbon accumulation,reconstruction and destruction periods using traditional isotopic dating methods is complex because of the small numbers of minerals that correlate with hydrocarbons.The quantitative and direct study of hydrocarbon geochronology is therefore an important scientific problem for isotope geochronology and petroleum geology.This study obtains two isotopic ages from a quartz vein sample associated with bitumen in a reverse fault located in the Bankeng paleo-reservoir on the southern margin of the middle Yangtze block (the northern margin of the JiangnanXuefeng uplift) by inclusion 40Ar/39Ar stepwise crushing in a vacuum.Two different and good linear inverse isochrons that correspond to two age plateaus were determined.The two ages correspond to primary inclusions of about 228 Ma and secondary inclusions of about 149 Ma.These inclusion groups represent two distinct kinds of fluids.Quartz veins associated with bitumen in faulted paleo-reservoirs,which have a strict response relationship with tectonization and hydrocarbon accumulation,are the unified products of tectonic processes,hydrocarbon accumulation and reconstruction.Therefore,they can be used to constrain the hydrocarbon accumulation,reconstruction and destruction periods that are controlled by multiphase and complicated tectonic actions.The evolutionary processes of hydrocarbon accumulation can be divided into two periods consisting of a primary oil and gas reservoir formation period in the late Indosinian epoch (about 228 Ma) and a period of oil and gas reservoir reconstruction in the early Yanshan epoch (about 149 Ma).This study quantitatively reconstructs the hydrocarbon accumulation and destruction chronological framework of a giant hydrocarbon accumulation belt along the southern margin of the middle Yangtze block (the northern margin of the Jiangnan-Xuefeng uplift) controlled by multiphase and complicated tectonism.The two ages associated with hydrocarbons here correspond to the special controlling actions of continental tectonics in the Jiangnan-Xuefeng uplift that affected the timeline of reconstruction and destruction in this giant marine hydrocarbon accumulation.This study shows the feasibility and usefulness of dating inclusions with the 40Ar/39Ar technique for hydrocarbon geochronology,especially in the marine hydrocarbon accumulation region of southern China within a geological setting of old strata,high thermal evolution hydrocarbons,and complex,multiphase and multicycle tectonization. | LIU ZhaoQian MEI LianFu QIU HuaNing SHEN ChuanBo TANG JiGuang YUN JianBing | 2011 | Chinese Science Bulletin2011,56,26: | 7 |
| 6 | 中扬子地块南缘半坑古油藏成藏期及破坏期的^(40)Ar/^(39)Ar年代学约束显示文摘因为与油气成藏作用相关的矿物种类较少,传统同位素测年法很难在油气成藏期方面展开应用,油气成藏年代的直接、定量研究是同位素年代学和石油地质研究面临的重大科学问题.本次研究对中扬子地块南缘(江南-雪峰隆起北缘)半坑古油藏断裂带内沥青伴生石英脉进行的包裹体40Ar/39Ar同位素真空击碎法测年实验,获得了两条截然不同的、线性相关均良好的反等时线,对应两个年龄坪,两期年龄分别对应228Ma左右的原生包裹体和149Ma左右的次生包裹体,代表了两期不同性质的流体行为.古油藏断裂带内沥青及伴生的石英脉体是构造作用和成藏及改造作用过程中的一体化产物,与构造作用和烃类运聚具有着非常严格的响应关系,可以约束多期复杂构造作用下油气成藏、改造和破坏的时间,据此将半坑古油藏成藏演化过程划分为晚印支期(228Ma左右)原生油气藏形成阶段和早燕山期(149Ma左右)油气藏改造阶段.本次研究重建了多期复杂构造作用控制下的中扬子地块南缘(江南-雪峰隆起北缘)巨型油气成藏带内油气聚集与改造/破坏的年代学格架,是江南-雪峰隆起北缘特殊大陆构造属性对海相油气巨量富集与改造/破坏的控制作用在时间链条上的体现.展示了流体包裹体40Ar/39Ar定年技术在油气成藏年代学方面,特别是在中国南方地层时代老、烃类演化程度高、多旋回构造作用背景下的海相油气成藏地区应用的可行性与良好前景. | 刘昭茜 梅廉夫 邱华宁 沈传波 汤济广 云建兵 | 2011 | 科学通报2011,56,33: | 5 |

| 9 | 自生矿物稀有气体同位素分析纯化新技术显示文摘矿物岩石样品经加热释放出的气体,除稀有气体外,还有各种活性气体.必须先除去这些活性气体,获得纯净的稀有气体,才能送入质谱仪进行稀有气体同位素分析或40Ar/39Ar定年分析.常规的纯化装置能满足多数地质样品的气体纯化要求.但是,一些矿物岩石样品含有较高的杂质成分,尤其是油气田储层砂岩自生伊利石等矿物,常规纯化装置不能完全除去杂气,影响了稀有气体分析和40Ar/39Ar定年的数据质量.本文介绍的有机杂气纯化系统是由多个可循环使用纯化装置组合而成,各个装置的工作温度和去气温度不同.样品释出的气体通过该套纯化系统后,能够有效地除去水、氮气、二氧化碳和有机挥发份等杂质气体.云母类矿物是40Ar/39Ar定年最主要的测试矿物之一,特殊环境形成的云母类矿物可能包含一些杂质,实验中发现一个白云母样品采用常规方法不能获得纯净的稀有气体,该白云母成为本次对比实验的研究对象.交替'关闭/开启'这套有机杂气纯化系统,分4部分进行实验对比.实验表明,关闭有机杂气纯化系统时,40Ar随测量时间呈曲线变化,气体纯化效果差,年龄误差大;开启新的纯化系统时,40Ar随测量时间呈直线下降,气体纯化效果好,年龄误差小,数据质量明显提高. | 何立言 邱华宁 施和生 朱俊章 白秀娟 云建兵 | 2015 | 中国科学:地球科学2015,45,10: | 1 |
| 10 | 非烃天然气CO_2的地质研究现状显示文摘二氧化碳(CO_2)地质研究处于刚刚起步阶段,在成因判识、地质源库脱气作用及成藏规律方面取得了一系列进展。CO_2成因判识可概括为组分含量/比值特征辨识和同位素辨识2个方面。CO_2地质源库有幔源岩浆、火山岩、碳酸盐岩和有机质4种,不同气源的脱气量、脱气方式及成藏贡献不同。CO_2气藏晚期成藏,主要受岩浆活动、气源断裂体系、上涌地幔和壳内高导低速体的制约。建议加强幔源—岩浆气源体的脱气机理和演化的基础研究,其次是幔源—岩浆气源体脱气与气源断裂系的耦合研究。 | 李振生 田晓莉 刘德良 | 2012 | 地球科学进展2012,27,S1: | 0 |
