Excessive carbon emissions have resulted in the greenhouse effect, causing considerable global climate change. Marine carbon storage has emerged as a crucial approach to addressing climate change. The Qiantang Sag(QTS) in the East China Sea Shelf Basin, characterized by its extensive area, thick sedimentary strata, and optimal depth, presents distinct geological advantages for carbon dioxide(CO_(2)) storage. Focusing on the lower section of the Shimentan Formation in the Upper Cretaceous of the QTS, this study integrates seismic interpretation and drilling data with core and thin-section analysis. We reveal the vertical variation characteristics of the strata by providing a detailed stratigraphic description. We use petrophysical data to reveal the development characteristics of high-quality carbon-storage layers and favorable reservoircaprock combinations, thereby evaluating the geological conditions for CO_(2) storage in various stratigraphic sections. We identify Layer B of the lower Shimentan Formation as the most advantageous stratum for marine CO_(2) storage. Furthermore, we analyze the carbon emission trends in the adjacent Yangtze River Delta region. Considering the characteristics of the source and sink areas, we suggest a strong correlation between the carbon emission sources of the Yangtze River Delta and the CO_(2) storage area of the QTS, making the latter a priority area for conducting experiments on marine CO_(2) storage.

苏门答腊盆地群是东南亚典型的弧后盆地,也是印度尼西亚第一大油气富集区,近5年发现新增油气储量呈上升趋势,待发现资源量大,具有较大的勘探潜力。通过系统梳理苏门答腊盆地群油气勘探历史、主要油气资源分布和盆地构造演化特征,分析了苏门答腊弧后盆地油气分布差异性及其主控因素。油气的不均一分布格局,主要受控于断陷期烃源岩的差异性分布,断陷期的“三阶段”构造演化过程控制不同类型的沉积环境及沉积相分布,进而影响主力烃源岩的分布;其次,地壳拉张变薄以及岩浆作用促使弧后地区浅层形成较高热流值,加速烃源岩的热解生烃。结合苏门答腊弧后盆地群油气勘探历史及其待发现油气资源量,认为苏门答腊盆地北部Andaman ⅢPSC区块等深水区、南苏门答腊盆地源下基底潜山新层系以及中苏门答腊盆地的陆上低程度勘探地区是下一步研究的新领域。

【目的】探究不同树龄胡杨叶功能性状的特征及其影响因素,揭示胡杨叶功能性状的种内变异及其适应特性,为胡杨的保护与管理提供理论依据。【方法】以不同树龄的胡杨为研究对象,通过相关性分析和方差分解等方法,研究胡杨叶片形态、光合生理、养分性状的变化特征以及对树龄和土壤因子的响应。【结果】随着树龄的增加,叶干物质含量、叶绿素a含量、叶绿素b含量、叶绿素总量以及叶片碳、氮、磷含量呈增加趋势,而比叶面积、叶厚度呈减小趋势。各叶功能性状之间存在一定的相关性,其中叶绿素a含量、叶绿素b含量、叶绿素总量与叶片碳含量、叶氮含量、叶磷含量、叶干物质含量协同变化,与比叶面积和叶片厚度权衡变化,并且性状间的关系受树龄调控。比叶面积、叶干物质含量、叶绿素a含量、叶绿素b含量、叶碳含量、叶氮含量、叶磷含量主要受土壤pH和树龄的影响,叶片厚度、叶绿素总量主要受土壤氮含量和树龄的影响,表明树龄、土壤pH、土壤全氮含量是胡杨叶功能性状的主要影响因子,并且与土壤因子相比,树龄对叶功能性状变异的解释率更高,可以解释胡杨叶功能性状15.1%~38.1%的变异。【结论】随着树龄的增加,胡杨通过一定的性状变异和性状组合适应环境的变化,各叶功能性状的影响因子不同,其中树龄和土壤因子共同调控叶功能性状的变化,并且树龄在决定胡杨叶功能性状变异方面可能起着更为关键的作用。

Characteristics of hydrocarbon accumulation and exploration potential of the northern South China Sea deepwater basins

引用

Chinese Science Bulletin 2012年第24期57卷 3121-3129页

作者： zhu weilin ZHONG Kai LI YouChuan XU Qiang FANG DianYong China National Offshore Oil Corporation Beijing I00010China China National Offshore Oil Corporation Research Beijing 100027China

Although the huge potential of the northern South China Sea deepwater basins has been proven by a series of discoveries that followed the exploration breakthrough of well LW 3-1-1, recent drilling and other studies have demonstrated the uniqueness and complicated nature of hydrocarbon accumulations of the deepwater basins there. Based on a review of previous work and the latest exploration activities and studies, the purpose of this paper is to discuss the critical controls for hydrocarbon accumulations in the deepwater basins of the northern South China Sea. A terrestrial-marine transitional coal-bearing source rock is proposed to be the primary source rock for the deepwater basins. A marine source rock, which was first identified as contributing to hydro-carbon generation in this region, probably plays a significant role in the deep-and ultra-deep water basins south to the Pearl River Mouth and Qingdongnan basins. The shelf margin delta depositional systems in the Baiyun Sag, sourced from the Pearl River, are currently primary exploration targets in the deepwater part of the Pearl River Mouth Basin, whereas the western Red River delta-ic-submarine fan depositional systems, initially proven by drilling, are the possible major exploration reservoirs in the Qing-dongnan deepwater areas. Current deepwater exploration targets at the large-sized structural traps and deep and ultra-deep areas in the south of the Pearl River Mouth and Qingdongnan basins will be the future exploration focus. Deepwater exploration activities and relevant fundamental studies, supporting and promoting each other, are of great importance to the national energy supply of China, the basic regional studies of the South China Sea, advancements in technology, and development of related deepwater industries, and will safeguard national sovereignty and territorial integrity.

New insights on the origin of the basement of the Xisha Uplift,South China Sea

引用

Science China Earth Sciences 2017年第12期60卷 2214-2222页

作者： zhu weilin XIE XiNong WANG ZhenFeng ZHANG DaoJun ZHANG ChengLi CAO LiCheng SHAO Lei State Key Laboratory of Marine Geology Tongji University Shanghai 200092 China Key Laboratory of Tectonics and Petroleum Resources Ministry of EducationChina University of Geoscience(Wuhan)Wuhan 430074China Zhanjiang Branch CNOOC LimitedZhanjiang 524057China Department of Geology Northwestern UniversityXi'an 710069China

The study of basement geochronology provides crucial insights into the tectonic evolution of oceans. However, early studies on the basement of the Xisha Uplift were constrained by limited geophysical and seismic data; Xiyong1 was the only commercial borehole drilled during the 1970 s because of the huge thickness of overlying Cenozoic strata on the continental margin. Utilizing two newly-acquired basement samples from borehole XK1, we present petrological analysis and zircon uranium(U)-lead(Pb) isotope dating data in this paper that enhance our understanding of the formation and tectonic features of the Xisha Uplift basement. Results indicate that this basement is composed of Late Jurassic amphibole plagiogneisses that have an average zircon 206 Pb/238 U age of 152.9±1.7 Ma. However, the youngest age of these rocks, 137±1 Ma, also suggests that metamorphism termination within the Xisha basement occurred by the Early Cretaceous. These metamorphic rocks have adamellites underneath them which were formed by magmatic intrusions during the late stage of the Early Cretaceous(107.8±3.6 Ma). Thus, in contrast to the Precambrian age(bulk rubidium(Rb)-strontium(Sr) analysis, 627 Ma) suggested by previous work on the nearby Xiyong1 borehole, zircons from XK1 are likely the product of Late Mesozoic igneous activity. Late Jurassic-Early Cretaceous regional metamorphism and granitic intrusions are not confined to Xisha; rocks have also been documented from areas including the Pearl River Mouth Basin and the Nansha Islands(Spratly Islands) and thus are likely closely related to large-scale and long-lasting subduction of the paleo-Pacific plate underneath the continental margins of East Asia, perhaps the result of closure of the Meso-Tethys in the South China Sea(SCS). Controversies remain as to whether, or not, the SCS region developed initially on a uniform Precambrian-aged metamorphic crystalline basement. It is clear, however, that by this time both Mesozoic compressive subduct
