Insights into microscopic oil occurrence characteristics in shales from the Paleogene Funing Formation in Subei Basin, China

引用

Petroleum Science 2025年第1期22卷 55-75页

作者： Jun-Jie wang Peng-Fei Zhang Shuang-Fang Lu zi-Zhi Lin Wen-Biao Li Jun-Jian Zhang Wei-Zheng Gao Neng-Wu Zhou Guo-Hui Chen Ya-Jie Yin Han Wu Sanya Offshore Oil & Gas Research Institute of Northeast Petroleum University College of Earth Science and Engineering Shandong University of Science and Technology Key Laboratory of Continental Shale Hydrocarbon Accumulation and Efficient Development Ministry of Education Northeast Petroleum University School of Geoscience China University of Petroleum (East China)

The microscopic occurrence characteristics primarily constrain the enrichment and mobility of shale *** study collected the lacustrine shales from the Palaeogene Funing Formation in the Gaoyou Sag, Subei Basin. Conventional and multistage Rock-Eval, scanning electron microscopy, and nuclear magnetic resonance(NMR) T1-T2were performed to analyze the contents and occurrence characteristics of shale oil. Low-temperature nitrogen adsorption-desorption(LTNA/D) experiments were conducted on the shales before and after extraction. The relationships between shale oil occurrence with organic matter and pore structures were then discussed. Predominantly, the shale oil in the Funing Formation is found within fractures, with secondary occurrences in interparticle pores linked to brittle minerals and sizeable intraparticle pores associated with clay minerals. The selected shales can be categorized into two types based on the nitrogen isotherms. Type A shales are characterized by high contents of felsic and calcareous minerals but low clay minerals, with larger TOC and shale oil values. Conversely, Type B shales are marked by abundant clay minerals but diminished TOC and shale oil contents. The lower BET specific surface area(SSA), larger average pore diameter, and simpler pore surfaces and pore structures lead to the Type A shales being more conducive to shale oil enrichment and mobility. Shale oil content is predominantly governed by the abundance of organic matter, while an overabundance of organic matter typically equates to a reduced ratio of free oil and diminished fluidity. The BET SSA, volumes of pores less than 25 and 100 nm at extracted state all correlate negatively with total and adsorbed oil contents but display no correlation with free oil, while they have positive relationships with capillary-bound ***, pore water is mainly saturated in micropores(<25 nm) and minipores(25-100 nm), as well as adsorbed oil, while free oil, i.e., bound and movable

由余评价秦人工程“使人为之,亦苦民矣”,战国时人言“秦人好兴事”。秦统一之后兴建的著名工程,则有长城、阿房宫、骊山以及驰道、直道等。后世史论、政论或认为,秦工程规模之大,致使人力资源的扼杀式消耗、社会民生的摧毁性损伤、经济秩序的全面化破坏,是引发秦短促而亡的重要原因之一。有迹象表明,秦大型工程是以军事化形式组织和管理,显示出极高的效率。其所付出的社会代价,尤其是民众的生命成本,则体现出惊人的残酷。汉初营建非常重要的营造项目亦多注意工程规划的合理与人力动员的收敛,对秦政相关内容取“拨乱反正”的态度,体现出历史走向进步的趋势。

目前在同一行业内使用着多种XML模式语言,因此XML数据转换已成为数据交换的研究热点。当前一些转换模型不能清晰而有力地描述转换语义,为此我们提出了一种关系树模型,它能有效地把XML层次化的特点和成熟的关系理论结合在一起,能处理XML元数据而不是XML实例,并支持DTD和W3C XML模式语言。基于这一模型的转换语义不仅能进行简单元素的映射,而且也能提供复杂关系代数运算的能力,例如整合。这种转换语义中还提供算术运算,极限运算,统计运算和关系演算等多种运算,增加了该模型的转换能力。

An ultra-wideband circularly polarized microstrip patch antenna loaded with split-ring resonator

引用

Optoelectronics Letters 2025年

作者： wang Shike XIA Dan Lü Lianrong QIN juan wang Meng REN Haiping School of Integrated Circuit Science and Engineering， Tianjin University of Technology

In this paper， the effect of a single-opening split-ring resonator （SRR） structure on the performance of ultra-wideband （UWB） microstrip patch antenna （MPA） is studied. Here a UWB MPA based on partial grounding is proposed， and the SRR structure is utilized to optimize other characteristics of the low-profile microstrip antenna while ensuring the bandwidth and gain remain unchanged. The proposed metamaterial structure， consisting of a 2 × 2 array of SRR， is loaded on the reverse side of the substrate. The volume of the proposed antenna is 61.6×67.6×1.5mm3. According to simulation and experimental results， the proposed microstrip antenna loaded with 2×2 SRRs performs better than that without SRR structure. It produces an operating band of 1.62 GHz-8 GHz while achieving circular polarization characteristics with an axial ratio （AR） bandwidth of 3.92 GHz-4.57 GHz. In addition， the performance of the proposed antenna is superior to relevant works of literature The antenna can be widely utilized in wireless communication systems.
