高校基层党组织党内政治生活作为高校党建工作的重要组成部分,是落实全面从严治党的重要环节。选用中国知网、万方学术期刊和维普期刊数据库为数据源,采用文献计量学方法,从文献类型、文献年度、被引频率、核心作者、研究机构、基金来源、研究热点等对检索到的325篇高校基层党组织党内政治生活研究相关文献进行分析,研究发现高校基层党组织党内政治生活研究的年度发文量在2018年出现峰值,发文量最多,达到60篇。“全面从严治党”“高校党建”“新时代”“组织生活”“大学生党员”“思想政治教育”“社会主义办学方向”等是高校基层党组织党内政治生活研究的热点;该领域持续研究的核心作者和研究单位不多;受到基金资助的研究项目也较少。因此,高校基层党组织党内政治生活研究需在研究深度、研究力量和支持力度方面进一步加强,在研究角度和范围方面还有待进一步的拓宽。

我国页岩油气的高效开发离不开大规模压裂技术。页岩油气大规模压裂过程时间长,压裂砂堵事故易发生且后果严重,开展其预警研究对页岩油气压裂施工安全意义重大。然而,目前仍缺乏压裂砂堵主控因素分析及其施工泵压预测的有效手段。针对此问题,考虑压裂机理和泵压变化特征,建立了一套压裂施工过程中泵压实时预测的方法,以开展砂堵预警研究。首先,采用压裂模拟器模拟压裂全过程泵压变化,通过改变不同流体性质与地层参数开展泵压变化规律的主控因素分析,并采用灰色关联分析方法进行主控因素排序。其次,基于断裂力学、支撑剂运移理论和长短时记忆神经网络(LSTM)模型,建立施工泵压预测框架及模型,形成机理和智能融合下的压裂砂堵预警方法,最后基于砂堵预警方法开展了现场压裂砂堵预警实例应用。结果表明,影响典型井施工泵压的因素由主到次依次为排量、流体黏度、主应力差、砂浓度、裂缝簇数及孔眼数。当其他参数不变时,随着流体黏度、主应力差及排量的增大,施工泵压增加;随着裂缝簇数、孔眼数及砂浓度增加,施工泵压降低。将该压裂砂堵预测方法应用于矿场实际,对压裂砂堵事故进行判识和预警,预测砂堵时间较现场人工识别提前19s,得到相对误差约为6.8%。建立的砂堵智能预警方法可靠性较好,预测泵压与现场泵压基本吻合,实现了压裂砂堵精确预警,对页岩油气压裂过程中砂堵预警具有良好的借鉴意义。

The circadian clock coordinates rhythms in numerous physiological processes to maintain organismal homeostasis. Since the suprachiasmatic nucleus(SCN) is widely accepted as the circadian pacemaker, it is critical to understand the neural mechanisms by which rhythmic information is transferred from the SCN to peripheral clocks. Here, we present the first comprehensive map of SCN efferent connections and suggest a molecular logic underlying these projections. The SCN projects broadly to most major regions of the brain, rather than solely to the hypothalamus and thalamus. The efferent projections from different subtypes of SCN neurons vary in distance and intensity, and blocking synaptic transmission of these circuits affects circadian rhythms in locomotion and feeding to different extents. We also developed a barcoding system to integrate retrograde tracing with in-situ sequencing, allowing us to link circuit anatomy and spatial patterns of gene expression. Analyses using this system revealed that brain regions functioning downstream of the SCN receive input from multiple neuropeptidergic cell types within the SCN, and that individual SCN neurons generally project to a single downstream brain *** map of SCN efferent connections provides a critical foundation for future investigations into the neural circuits underlying SCNmediated rhythms in physiology. Further, our new barcoded tracing method provides a tool for revealing the molecular logic of neuronal circuits within heterogeneous brain regions.

Carbon capture and storage （CCS） technology has been considered as an important method for reducing greenhouse gas emissions and for mitigating global climate change. Three primary options are being considered for large-scale storage of CO2 in subsurface formations： oil and gas reservoirs, deep saline aquifers, and coal beds. There are very many large saline aquifers around the world, which could make a big contribution to mitigating global warming. However, we have much less understanding of saline aquifers than oil and gas reservoirs. Several mechanisms are involved in the storage of CO2 in deep saline aquifers, but the ultimate goal of injection of CO2 into the aquifers containing salt water is to dissolve the CO2 in the water. So it is important to study the solubility trapping and sensitivity factors of CO2 in saline aquifers. This paper presents results of modeling CO2 storage in a saline aquifer using the commercial reservoir simulator ECLIPSE. The objective of this study was to better understand the CO2/brine phase behavior （PVT properties） and quantitatively estimate the most important CO2 storage mechanism in brine-solubility trapping. This would provide a tool by performing theoretical and numerical studies that help to understand the feasibility of CO2 geological storage. A 3-dimensional, 2-phase （water/gas） conceptional reservoir model used finite, homogenous and isothermal formations into which CO2 is injected at a constant rate. The effects of main parameters were studied, including the vertical to horizontal permeability ratio kv/kh, salinity, and residual phase saturations. The results show that the vertical to horizontal permeability ratio has a significant effect on CO2 storage. Moreover, more CO2 dissolves in the brine at lower kv/kh values.

裂缝性气藏在我国油气资源中具有重要地位,其试井分析对储层评价和气藏开发具有不可或缺的作用。为了解决传统双重孔隙介质模型对天然裂缝表征不精确的难题,基于蒙特卡罗随机模拟方法和离散裂缝模型,表征了复杂分布的天然裂缝,构建了考虑离散裂缝和渗透率非均质性的径向复合裂缝性气藏数值试井模型(DFM-NM),绘制了不同参数下裂缝性气藏气井试井曲线图版,形成了解析试井初拟合、离散裂缝细拟合的试井分析方法,并开展了实例应用分析。研究结果表明:(1)裂缝性气藏不稳定流动阶段包括井筒储集和表皮效应阶段、内区裂缝影响阶段、内区径向流阶段、外区裂缝影响阶段和边界控制流阶段;(2)基于地质条件约束下的离散裂缝模型能较好表征复杂、非均质裂缝性气藏,克服了常规双重孔隙介质模型的缺点;(3)裂缝数目越多、裂缝平均长度越长,压力导数曲线下凹的幅度越大,内区裂缝参数对试井曲线形态的影响更大。结论认为,所建立的裂缝性气藏数值试井模型及粗细分步拟合方法适用于塔里木盆地裂缝性气藏,能更准确有效地评价储层、反演裂缝参数。研究成果具有良好的应用前景,可为裂缝性气藏参数反演和开发方案优化提供理论支撑,有助于我国复杂油气资源的科学开发。
