Since 2017, a plenty of gas hydrates have been drilled in a new area of Shenhu, and good heterogeneity has been found throughout the spatial distribution of the reservoir. After distinguishing different sedimentary sequence types and matching their formation with slope deposition settings, this study proposes three mass transport deposit(MTD) patterns related to canyon activity that occurred contemporaneously or epigenetically with it: well preserved MTDs, MTDs eroded by canyon migration, and MTDs dislocated by contemporaneous faults. Based on seismic reflection characteristics, this study proposed methods of quantitatively analyzing sedimentary factors,such as measuring the turbidities flow rate in the canyon, and results are interpreted with respect to canyon activity. Combining the above parameters and their relationship with gas hydrate accumulation, fine-grained seals overlapping coarse MTDs reservoirs are found to be indispensable to gas hydrate accumulation, as they prevent the release of free gas. Based on grain size data of hydrate samples from drilling wells, multi-layered gas hydrate reservoirs capped by fine-grained sediments and overlapping mud show favorable hydrate-bearing prospects. The release of gas hydrates, however, is mostly caused by the lack of mud sealing in relation to canyon activity, such as turbidities flow erosion and contemporaneous fault breaking. Canyon migration with respect to MTDs may be the actual cause of erosion of overlapping syn-sedimentary layers, and high bottom flows may contribute to an increase in the release of free gas. It is believed that contemporaneous faults caused by unstable canyon walls may break the muddy over layers and decrease the accumulation pressure of gas hydrate ***, according to the sedimentary characteristics of MTDs and the hydrate accumulation process, three responding accumulation or releasing patterns are proposed, which respond to the different types of MTDs distinguished above: a well-pr

Sedimentology and Sequence Stratigraphy of Marine to Lacustrine Deltaic Deposits in a Craton Basin and Their Controlling Factors: Shan 2 Member–He 8 Member(Guadalupian–Lopingian, Permian), Southeast Ordos Basin, North China

Acta Geologica Sinica(English Edition) 2018年第1期92卷 268-285页

作者： SHAN Xin YU Xinghe Peter CLIFT LI Yalong jin lina SU Dongxu DU Yonghui ZHOU jinsong HAN Xiaoqin Key Laboratory of Marine Sedimentology and Environmental Geology First Institute of Oceanography State Oceanic Administration Qingdao 266061 Shandong China Laboratory for Marine Geology Qingdao National Laboratory for Marine Science and Technology Qingdao 266061 China School of Energy Resources China University of Geosciences Beijing 100083 China Department of Geology and Geophysics Louisiana State University Baton Rouge 70803 USA School of Ocean and Earth Science Tongji University Shanghai 200092 China Research Institute of Shaanxi Yanchang Petroleum (Group) Company Limited Xi 'an 710065 Shaanxi China

The Shan 2 Member, Shan 1 Member and He 8 Member of the Mid-Late Permian Shanxi and lower Xiashihezi formations, in the southeastern Ordos Basin, together comprise -150 m of deltaic deposits. This sequence records an overall evolution from deep marine environment to shallow lake associated with braided river, braided river delta and meandering river delta. Core description, well log interpretation, and stable isotope analysis, including carbon, oxygen and strontium, were conducted to understand the sedimentary evolution of Shan 2 to He 8 Member. The Shanxi Formation, which consists of the Shan 2 and Shan 1 members, is characterized by a tidal-influenced meandering river delta environment and a higher j13C value and S7Sr/S6Sr ratio and a lower jlSo value. The He 8 Member, the basal part of the Xiashihezi Formation, is featured by a braided river to braided river delta system and a lower j13C value, S7Sr/S6Sr ratio, and a higher jlSo value. Four third-order depositional sequences separated by five sequence boundaries are determined. Coarsening upward sequences of the Shan 2 Member-He 8 Member indicate a general regression trend, which can be correlated to global sea-level fall occurring during the Roadian-Wuchiapingian, as also evidenced by previous published zircon U-Pb results. The coal-bearing sequence （Shanxi Formation） to non-coal-bearing sequence （He 8 Member）, as well as a decrease of 87Sr/86Sr, suggest a trend from humid to arid climates. A combined effect of sea-level drop and a small uplift at the end of Shanxi Formation are proposed.

基于多年的田野调查,文章提出赫哲语动词具有人称范畴,并运用语言类型学方法探讨赫哲语动词的人称问题。赫哲语的人称一致标记均为后缀,从形态和音系特征来看,人称代词是人称后缀的主要来源。动词的人称变化体现谓语和小句主语的人称信息编码模式,形动词、副动词、谓语动词的人称变化不完全相同,陈述式、祈使式、条件式谓语动词与小句主语的人称一致关系也有区别。主语是一致关系的控制项,其生命度与有定性影响和制约动词的人称一致标记。赫哲语动词人称一致标记的使用具有较强的规律性,但是已出现简化趋势。
