1Variation and mechanisms of clastic reservoir quality in the Paleogene Shahejie Formation of the Dongying Sag, Bohai Bay Basin, China显示文摘Reservoir quality varies greatly in the Shahejie Formation in the Dongying Sag. It is essential to analyze the variation and mechanisms of reservoir quality for determining the controlling factors based on cores, porosity measurements and fluid inclusion techniques and so on. The sandstones in the fluvial,(fan) delta-front have the best reservoir quality due to the depositional conditions mechanically controlling the petrology configuration and the primary porosity, and chemically influencing the diagenesis and development of secondary pores. The activity of the boundary faults and the sedimentary facies dominate the variation of reservoir quality in different areas and intervals. The reservoir quality varies with the position of sandstone beds in different vertical models of sandstone and mudstone. This mainly arose from the strong cementation or strong dissolution in the sandstone caused by the diagenesis evolution of adjacent mudstone. With higher oil saturation reservoir quality is better because the hydrocarbon charge favors dissolution and restricts cementation. Diagenesis, depositional conditions and tectonic setting are the key controls of reservoir quality in the Shahejie Formation of the Dongying Sag.Zhang Qin Zhu Xiaomin Ronald J Steel Zhong Dakang 2014Petroleum Science2014,11,2:16
2Jurassic sedimentary evolution of southern Junggar Basin:Implication for palaeoclimate changes in northern Xinjiang Uygur Autonomous Region,China显示文摘Junggar Basin,located in northern Xinjiang,presents continuous and multikilometer-thick strata of the Jurassic deposits.The Jurassic was entirely terrestrial fluvial and lacustrine deltaic sedimentation.Eight outcrop sections across the Jurassic strata were measured at a resolution of meters in southern Junggar Basin.Controlling factors of sedimentary evolution and palaeoclimate changes in Junggar Basin during the Jurassic were discussed based on lithology,fossils and tectonic setting.In the Early to Middle Jurassic,the warm and wide Tethys Sea generated a strong monsoonal circulation over the central Asian continent,and provided adequate moisture for Junggar Basin.Coal-bearing strata of the Badaowan,Sangonghe,and Xishanyao Formations were developed under warm and humid palaeoclimate in Junggar Basin.In the late Middle Jurassic,Junggar Basin was in a semi-humid and semi-arid environment due to global warming event.Stratigraphy in the upper part of the Middle Jurassic with less plant fossils became multicolor or reddish from dark color sediments.During the Late Jurassic,collision of Lhasa and Qiangtang Block obstructed monsoon from the Tethys Sea.A major change in climate from semi-humid and semi-arid to arid conditions took place,and reddish strata of the Upper Jurassic were developed across Junggar Basin.Shun-Li Li Xing-He Yu Cheng-Peng Tan Ronald Steel 2014Journal of Palaeogeography2014,3,2:15
3A Climatic Sequence Stratigraphic Model in the Terrestrial Lacustrine Basin:A Case Study of Green River Formation,Uinta Basin,USA显示文摘在最近的年里,与陆上的顺序地层学的发展,更多的注意全球性集中于陆上的湖的顺序 stratigraphic 模型的学习。不同观点被研究人员比较喜欢。在顺序地层学的理论的指导下面,这篇论文的调查结果显示气候是控制第四顺序的顺序的形成的一个主要因素,在 USA 在 Uinta 盆的格林河形成在顺序地层学的学习之上基于。它也在陆上的湖的盆把第四顺序的顺序划分成二条系统道:湿(升起) 一半周期并且干燥(掉落) 一半周期,为陆上的湖的盆建立一个新式的第四顺序的顺序 stratigraphic 模型,也就是说气候基因的顺序 stratigraphic 模型。作为结果,顺序地层学的理论极大地被充实。WANG Junling ZHENG Herong XIAO Huanqin ZHONG Guohong Ronald STEEL YIN Peigui 2009Acta Geologica Sinica(English Edition)2009,83,1:4
4碎屑岩深水扇研究显示文摘由于认识到深水储层中富存烃类,碎屑岩深水扇引起了地质学家的兴趣。近年来,碎屑岩深水扇的研究取得了相当大的新进展,回顾和总结近年来该领域取得的进步和提出的新观点,总的来说,这些新的观点包括:碎屑岩深水扇不仅在低位体系域时产生,在沉积供给充足的高位体系域时也能够出现,但有时即使低位体系域时也不能形成深水扇;碎屑岩深水扇通常为浊流成因,但也有一些为碎屑流引起,其内部向上变粗或变厚的反韵律不明显。基于这些新观点,一些新的深水扇模式被提出,这些新的碎屑岩深水扇的模式对其形成和性质的因素,如海平面变化、构造、沉积速率、深水扇类型和性质等,考虑更加全面。结合这些新的认识,提出的深水扇模式包括:富砾、富砂、泥砂混合和富泥型模式,而每种又根据物源的性质分为点物源,线物源和多物源、这些模式考虑因素更加全面、精确,更能反映深水扇的实质,它是深水烃类勘探预测砂体分布有效的工具。阮伟 Ronald J Steel 黄洁 2010海洋地质与第四纪地质2010,30,1:1

15High-quality-factor tantalum oxide nanomechanical resonators by laser oxidation of TaSe2显示文摘Controlling the strain in two-dimensional (2D) materials is an interesting avenue to tailor the mechanical properties of nanoelectromechanical systems. Here, we demonstrate a technique to fabricate ultrathin tantalum oxide nanomechanical resonators with large stress by the laser oxidation of nano-drumhead resonators composed of tantalum diselenide (TaSe2), a layered 2D material belonging to the metal dichalcogenides. Before the study of their mechanical properties with a laser interferometer, we verified the oxidation and crystallinity of the freely suspended tantalum oxide using high-resolution electron microscopy. We demonstrate that the stress of tantalum oxide resonators increases by 140 MPa (with respect to pristine TaSe2 resonators), which causes an enhancement in the quality factor (14 times larger) and resonance frequency (9 times larger) of these resonators.Santiago J.

16澳大利亚西北大陆架中新世陆架边缘三角洲及其对深水陆坡进积作用和形态的影响显示文摘澳大利亚西北大陆架卡那封盆地北部晚-中中新世到上新世发育硅质碎屑岩的三角洲沉积。部分三角洲朵叶体在陆架坡折附近沉积(陆架边缘三角洲),而其他朵叶体在向陆后退或夭折前并没有延伸到同时代的陆架坡折处。陆架边缘三角洲主要集中在研究区北部,陆架边缘坡折的平面形态是从线性变化为向海一侧凸出的形态。陆架边缘三角洲的位置和特征也对边缘进积走向的变化和陆架边缘轨迹产生显著影响。中中新世晚期-晚中新世,南部陆架边缘坡折,总进积距离为13km,不发育陆架边缘三角洲;在陆架边缘三角洲发育区域的北部坡折进积约34km;中部地区的三角洲进积距离没有北部大,以加积特征为主,分布在陆架坡折向陆数千米的范围。这表明陆架边缘轨迹分析的适用条件只有在陆架边缘三角洲发育的地方沉积物供给充足,陆架边缘轨迹特征与相对海平面波动的响应才可靠。在同时代陆坡上发育典型的小规模侵蚀(约400m宽),甚至在三角洲达到陆架坡折前也能看到此侵蚀现象。然而,就在活动陆架边缘三角洲下倾方向的陆坡沟槽显示对下伏地层更大的侵蚀,陆坡沟槽(宽大于1km,深度约100m)比侧向上偏移三角洲沉积中心的同时代侵蚀水道(宽0.7km,深约25m)更宽、更深。本研究表明陆坡沟槽尺寸的变化是由于紧邻陆架边缘三角洲地区沉积重力流产生更大侵蚀的结果。同时,沟槽也进一步侵蚀(达6km)到活动陆架边缘三角洲地区的外陆架。Carla M.
