Utilizing Dynamic Data to Quickly Evaluate Advantageous Channels and Applications

In response to the high cost and difficulty of high-speed development and testing data in offshore oil fields, this paper proposes to use the most easily available production performance data as the basis and use the grey correlation method to calculate the correlation coefficient between oil and water wells to characterize the degree of development of advantageous channels. The consistency between the calculated results of this method and the tracer test results is over 80%. Based on the fitting results, the correlation coefficient exceeds 0.74 to determine the existence of an advantageous channel. According to the research results of grey correlation method, Bohai K oilfield has completed the combined profile control and flooding measures, and the daily oil production has increased by 20 m3/d. This method is simple, fast, and can achieve quantitative evaluation, which saves time and investment compared to offshore testing. It has strong application and reference value for the development of other offshore water injection oilfields.

SEDIMENTARY PATTERN OF PROTOTYPE BASIN IN THE DEPOSITION PERIOD OF LAIYANG FORMATION AND THE ADVANTAGEOUS AREAS FOR OIL AND GAS EXPLORATION OF JIAOLAI BASIN

Laiyang formation of Jiaolai Basin is the target stratum for oil and gas exploration. By measuring several field sections, the authors find that Laiyang formation reveals the whole processes from development to death of the lake basin and its sedimentary facies differ in different structural locations. Analyses about sedimentary facies and paleocurrent orientations in association with researches about the positive tectonic units such as Dayetou horseback and Chaigou horst indicate that Laiyang sag is a relatively independent sedimentary unit that shows great water depth typical of deep lake or semideep lake and was controlled by Wulongcun fault during the deposition period of Laiyang formation. Its sediments mainly originated from Jiaobei uplift area and Dayetou horseback. Gaomi-Zhucheng sag was a fast-filled basin controlled by Wurong fault and Yishu fault zone, being high in the northeast and low in the northwest and characterized by the development of pluvial facies and fluvial facies in most areas, and with the development of lake facies being limited to local low-lying regions. Selection of advantageous hydrocarbon reservoir areas for exploration purpose mainly relies on the sedimentation pattern of prototype basin and conservation conditions. The central-west area of Laiyang sag covered by overlying Laiyang formation is the most advantageous exploration area.

Comparative Advantage and Latecomer Advantage

To achieve development,developing countries must capitalize on their relative advantages,including comparative advantage and latecomer advantages.A country must develop an industrial structure that is consistent with the comparative advantage of its factor structure in order to avoid the trap of“structural catch-up”that stifles development.The issue for developing countries is that their comparative advantage in core factors of production is unstable and tends to decrease and dissipate.Such a comparative advantage cannot provide adequate growth for convergence to occur.Developed countries,on the other hand,can sustain economic growth due to their comparative advantage in high-quality factors.Latecomer advantage refers to the ability of developing countries to increase their knowledge factor in a cost-effective manner by learning,importing,assimilating,and using knowledge and technology that already exist.Although comparative and latecomer advantages may have a combined effect,each has its distinct characteristics.Latecomer advantage is a special development factor that applies to latecomers.It is crucial at all stages of development,but especially so in the middle-income stage and beyond.Bringing latecomer advantage into full play is essential for developing nations to converge with the advanced countries.

融合执行力与适应性:基层治理的制度优势分析

基层是国家制度传导的神经末梢,其治理效能的有效发挥是制度优势最直接的体现。新时代十年来,我国各领域基础性制度框架基本建立,但发展不平衡不充分问题仍然突出,信息公开、垃圾分类等基层治理中的制度优势彰显不足。制度优势向治理效能转化是国家治理的应然逻辑,转化过程中的动态机制、信任关系都会影响到制度执行的效果。单纯以制度执行力评判制度优势和治理效能略显偏颇,制度之所以具备优势,在于其能体现公平正义、呼应人之需求。而不同人的利益追求、目标取向、认知结构均不相同,这导致基层治理中制度出现适应性问题。经由理论层面的合理补充与实然层面的动态修复,融合执行力与适应性,有望打通制度优势、运行机制、信任支撑、治理效能的闭合回路,从而加快制度优势向基层传导,并反向以基层治理效能倒逼各类制度优化完善。

中、美、日、韩新能源汽车产业竞争优势测度与比较研究——以锂电池汽车为例

本文基于中、美、日、韩近30年在锂电池汽车领域的专利数据,选取20个关键指标构建“技术-经济-法律”三维分析模型,并划分出关键核心专利,在此基础上应用景气综合指数法计算四国在锂电池汽车产业的竞争优势指数,并对其进行比较与分析。结果表明,中、美、日、韩在锂电池汽车领域的总体发展布局已基本到达顶峰,且于近两年呈现波动下降趋势。总体来看,美国获得竞争优势时间最早且指数发展趋势最为稳定,连续多年稳居第一;中国获得竞争优势时间最晚,但指数发展速度最快,截至2021年末,中国总体竞争优势指数与美国持平,远超日、韩两国。分维度来看,中、美分别于经济、技术维度具有绝对竞争优势;韩国在经济、法律维度发展较为稳定,但技术维度影响整体,导致整体呈现波动下降趋势;日本在各维度均呈现出明显下降趋势,仅在技术维度下降幅度较小。由此得出结论:中国经济发展带动整体,已基本实现锂电池汽车产业的技术赶超,技术维度的发展是获得持续性竞争优势的基础,因此应在保持现有锂电池汽车领域竞争优势的同时注重相关技术轨道的跨越与变迁,以获取新能源汽车产业的持续性竞争优势。

中医药治疗青春期多囊卵巢综合征的现代机制研究进展及优势

多囊卵巢综合征(PCOS)是与内分泌异常、生殖功能障碍关系密切的一种疾病,以雄激素过高、持续无排卵或胰岛素抵抗为重要特征。PCOS多于青春期起病,青春期PCOS患病率逐年升高,发病年龄逐渐提前,患者除了有闭经、肥胖、痤疮、多毛等常见的症状外,还有可能产生焦虑、自卑等心理障碍,这给许多青春期女性带来困扰,应积极地予以临床干预。传统医学认识青春期PCOS注重脏腑,认为本病病机为肾虚,兼以脾虚、肝郁;现代医学的认识则进展为信号通路靶向的细胞进程,主要涉及Wnt/β-catenin、PI3K/Akt/mTOR等信号通路。目前,对于青春期PCOS目前尚无统一标准的诊疗方案,在临床中,除常用的西药治疗外,可以采用中药及中医特色治疗进行积极、及时的干预。本文对青春期PCOS的中医药治疗方法及现代机制研究进展进行综述,以期对青春期PCOS的治疗提供多种途径的治疗方法。

扬长避短:优势使用视角下知识异质性对越轨创新的影响机制研究

有效利用员工优势资源提高竞争力是企业关注的重点,但目前对于如何有效化解组织内非协同性导致的认知冲突尚未给予关注。鉴于此,关注知识异质性的双重属性,结合个体优势使用理论,通过问卷调查的形式收集到381份问卷数据,实证分析知识异质性对越轨创新影响过程中员工优势使用的中介作用以及领导权变激励的边界条件。结果表明:(1)知识异质性能够对越轨创新产生积极影响;(2)员工优势使用在知识异质性与越轨创新之间具有部分中介作用,即知识异质性可以促进员工的优势使用,进而对越轨创新产生积极影响;(3)领导权变激励会强化员工优势使用与越轨创新之间的正向关系,同时正向调节知识异质性通过员工优势使用影响越轨创新的间接效应。据此,提出企业应重视和开发知识异质性员工的价值、重视员工优势的开发,并采取及时有效的领导激励,以充分利用员工差异化知识储备、将员工自身优势转化为创新性成果,使企业能够长期保持核心竞争优势。

结合优势结构和最小目标Q值的深度强化学习导航算法

针对现有基于策略梯度的深度强化学习方法应用于办公室、走廊等室内复杂场景下的机器人导航时,存在训练时间长、学习效率低的问题,本文提出了一种结合优势结构和最小化目标Q值的深度强化学习导航算法.该算法将优势结构引入到基于策略梯度的深度强化学习算法中,以区分同一状态价值下的动作差异,提升学习效率,并且在多目标导航场景中,对状态价值进行单独估计,利用地图信息提供更准确的价值判断.同时,针对离散控制中缓解目标Q值过估计方法在强化学习主流的Actor-Critic框架下难以奏效,设计了基于高斯平滑的最小目标Q值方法,以减小过估计对训练的影响.实验结果表明本文算法能够有效加快学习速率,在单目标、多目标连续导航训练过程中,收敛速度上都优于柔性演员评论家算法(SAC),双延迟深度策略性梯度算法(TD3),深度确定性策略梯度算法(DDPG),并使移动机器人有效远离障碍物,训练得到的导航模型具备较好的泛化能力.

阿拉山口口岸开放特征分析及对策建议

阿拉山口口岸位于我国新疆博尔塔拉蒙古自治州境内,是第二亚欧大陆桥中国段的西桥头堡,是我国向西开放的重要门户。本文先从自然资源和政策扶持两个角度,探讨了阿拉山口口岸开放的优势和机遇。其次,从口岸能力、综合保税区、中欧班列和外贸新模式等几个方面对阿拉山口口岸的开放特征进行分析。进一步地,研究得出目前阿拉山口口岸在政策落地实施、产业发展不平衡以及人才储备等方面存在不足。未来阿拉山口地区应该利用现有的政策红利,积极推动数字口岸建设、多功能物流基地建设和现代化产业链建设,以促进口岸从“通道经济”向“产业经济”的转型,有力带动博州以及周边地区的经济发展。

资源环境约束下内蒙古如何为服务国家粮食安全贡献力量

粮食安全是“国之大者”。党的二十大报告指出,“要全方位夯实粮食安全根基,牢牢守住18亿亩耕地红线,确保中国人的饭碗牢牢端在自己手中”。内蒙古作为祖国北疆重要的“粮仓”“肉库”“奶罐”,在国家粮食安全中扮演重要的角色。在现有生产和供给基础上,可通过进一步提升耕地质量、优化种养殖结构、改造盐碱地等边际土地增加农业后备用地,“藏粮于地”“藏粮于技”,充分发挥内蒙古在粮食和重要农畜产品的比较优势,多措并举为切实服务保障国家粮食安全功能贡献力量。
