| 1 | Depositional and Diagenetic Controls on Sandstone Reservoirs with Low Porosity and Low Permeability in the Eastern Sulige Gas Field, China显示文摘In order to determine the genesis and the factors that control the low-porosity and lowpermeability sandstone reservoirs in the eastern Sulige Gas Field in the Ordos Basin, systematic studies on the sedimentary facies and diagenesis were conducted by means of analysis of cores, thin sections, fluid inclusions, X-ray diffraction, cathode luminescence and scanning electron microscope. It was found that the sand bodies of the major gas reservoirs in the Shan1 section(P1S1) and the He8 section(P2H8) were formed during the Permian as sedimentary facies such as braided-channel bars, braided-river channels and point bars of a meandering river. Four types of diagenetic facies developed subsequently: in order from the best to the poorest properties these are type A(weak compaction, early calcite cement-chlorite film facies), type B(moderate compaction, quartz overgrowth-feldspar corrosion-kaolinite filling facies), type C(strong compaction, late calcite cement-quartz corrosion facies) and type D(matrix filling and strong compaction facies). This diagenesis is undoubtedly the main reason for the poor reservoir properties of sandstone reservoirs, but the sedimentary facies are the underlying factors that greatly affect the diagenesis and thus the reservoir performance. Favorable diagenetic facies developed mainly in relatively small lithofacies such as braided-river channels, channel bars and point bars. The vertical distribution of the physical properties and the diagenetic facies of the reservoirs are related to the stratigraphic succession. Most of the sandstones between mudstones and thin beds of sandstone are unfavorable diagenetic facies. Analyses indicate that siliceous cementation can hardly be stopped by hydrocarbon filling. Authigenic chlorite could hardly protect the primary porosity. It not only occupies pore space, but also blocks pathways through sandstone reservoirs, so that it has significant influence on the permeability. Authigenic chlorite cannot be used as a marker for a specific sedimentary facies because it can be formed in different sedimentary facies, but it indicates high hydrodynamic conditions and presence of favorable reservoirs. | YANG Renchao FAN Aiping A.J.van LOON HAN Zuozhen WANG Xiuping | 2014 | Acta Geologica Sinica(English Edition)2014，88，5： | 16 |
| 2 | 要使查寻科技期刊论文方便快捷——Ⅳ.首页的重要性显示文摘一篇论文首页的复印件通常比整篇论文发送更广,因此,首页提供有效、高效地查到出处所需的全部信息(特别是刊名和卷号),是极为重要的。首页上的附加资料(明确的篇名、有关作者的资料、详细的摘要以及有效的关键词)可使论文更易于从数据库中检索到。从而增强该文和该刊的影响。 | A.J.van Loon | 1996 | 中国科技期刊研究1996，7，3： | 8 |
| 3 | 要使查寻科技期刊论文方便快捷——Ⅰ.应考虑的诸方面显示文摘只有查寻到论文出处,才能见到论文。然而,期刊中的论文查寻常因作者提供的资料含糊不全或编辑和出版者提供的信息不够充分而遇到困难。因此,编辑和出版者有必要为他们期刊中的论文查寻提供方便——他们应遵循某些基本规则。这些规则主要与一种期刊作为一个整体的外观、一期期刊的外观以及每篇论文特别是论文首页的外观有关。对于应考虑的最重要的诸方面都作了阐述。 | A.J.van Loon 董耿 | 1995 | 中国科技期刊研究1995，6，4： | 0 |
| 4 | Palaeogeographical development of two merging delta systems(Eocene Shahejie Formation)in the Bohai Bay Basin,E China and implications for hydrocarbon exploration显示文摘Two deltas developed simultaneously during the Eocene on the eastern side of a large lake that existed in the Dongying Sub-basin,which forms part of the Bohai Bay Basin in eastern China.The rivers that built the deltas had different catchment areas,which resulted in sediments with different permeability and porosity,due to differences in sorting and mud content.Both deltas prograded,and mass flows that originated frequently on their fronts formed lobes that expanded laterally.This eventually led to merging of both deltas,a feature that has rarely been described from ancient deposits thus far.Core analysis and seismic reflection data show that the merging of the two deltas took place in nine phases,determined by phases of slower progradation or even temporary retrogradation in between.The alternation of sediments from both deltas and their eventual mixing makes the architecture of the merged deltas much more complex than that of'classical'single deltas.This affects the predictability of the spatial distribution of possible reservoir characteristics significantly,but detailed core analysis shows that the best hydrocarbon reservoirs consist of sand bodies formed in distributary channels on the delta plains,and of sandy turbidites formed in the deep-lacustrine environment in front of the merged deltas. | Ren-Chao Yang Yang Li Ai-Ping Fan A.J.Van Loon(Tom) Jin Li Zuo-Zhen Han Jie Chen | 2023 | Journal of Palaeogeography2023，12，4： | 0 |
