The northward subduction of the Neo-Tethys oceanic crust triggered multiple magmatic activities in the West Myanmar Arc,which in turn influenced the deposition of sedimentary pyroclastic rocks from the Cretaceous to Eocene strata in the Central Myanmar Basin(CMB).The pore structure of these lithologic reservoirs is complex and rich in tuffaceous sandstone,which plays an adverse role in reservoir development in this *** understand the development characteristics and genetic mechanism of the pyroclastic rocks within three sets of reservoirs in this area,a comprehensive analysis was conducted through borehole core observations,thin section identification,scanning electron microscope analysis,and mercury injection *** tuffaceous sandstone from the upper Cretaceous to the Eocene is dominated by intermediate-acid volcanic rock *** pyroclastic rocks exhibit evident chloritization and ironization,with residual intergranular pores being the principal type accompanied by a smaller amount of intergranular dissolved pores and intragranular dissolved *** highest porosity is observed in the Eocene tuffaceous sandstone,ranging from 8%to 12%.The Late Cretaceous to Paleocene sandstones exhibit lower porosity levels of only 4%-6%.These reservoirs are characterized by their low porosity and *** the presence of a good source rock in this area,the volcanic debris particles filling the pores,as well as their subsequent devitrification,chloritization,and limonite mineralization,result in pore throat blockage and *** reservoirs in this area are small in size,exhibit poor reservoir connectivity and lateral continuity,and fail to meet the necessary conditions for commercial-scale hydrocarbon accumulation and migration.

Carbon Storage Dynamics in Lower Shimentan Formation of the Qiantang Sag, East China Sea Shelf Basin: Stratigraphy, Reservoir ‒ Cap Analysis, and Source ‒ Sink Compatibility

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。

在现代化进程中,资本、技术、人力与土地的有机结合,使农村土地具有了较大增值空间,也给农村土地腐败带来了可乘之机。农村土地腐败问题之所以产生,利益驱动下的多元主体竞相介入获取利益是土地腐败的内在驱动力。不同利益主体之间通过各种策略相互博弈,在利益冲突中相互妥协并构建利益结盟,是土地腐败的实践过程表达。在多元主体参与的博弈中,权力主体与资本主体各有所图,权力主体在维护公共利益的同时追求个人利益,资本主体具有趋利性。为实现各自利益最大化,有权主体往往利用掌握的权力与能够带来巨大经济利益的资本主体相互交融、妥协,进而共谋,达成共识,侵害广大农民的合法土地财产权利,农村土地腐败由此产生。当然,防止土地腐败问题的发生,还需要从法制建设、制度建设等层面寻找突破口。
