Sand control mechanism of radial well filled with phase change material in hydrate reservoir

Petroleum Science 2024年第4期21卷 2571-2582页

Radial well filled with phase change material has been proposed as a novel sand control method for hydrate exploitation. In order to reveal the sand control mechanism, CFD-DEM coupling method is applied to simulate the migration, settlement, and blockage processes of sand particles in the radial *** obtained results indicate that three scenarios have been recognized for sand particles passing through sand control medium, based on the diameter ratio of sand control medium to sand particle（Dd）:fully passing（Dd= 8.75-22.5）, partially passing and partially blocked（Dd= 3.18-5.63）, and completely blocked（Dd= 2.18-3.21）. After being captured by the sand control medium, sand particles can block pores, which increases fluid flow resistance and causes a certain pressure difference in the radial *** pressure in the radial well should be lower than the hydrate phase equilibrium pressure during sand control design, for the purpose of promoting hydrate decomposition, and sand capture. The length of the radial well should be optimized based on the reservoir pore pressure, production pressure difference,bottom hole pressure, and the pressure gradient in the radial well. It should be noticed that the sand control medium leads to a decrease in permeability after sand particles captured. Even the permeability is reduced to several hundred millidarcy, it is still sufficient to ensure the effective flow of gas and water after hydrate decomposition. Increasing fluid velocity reduces the blocking capacity of the sand control medium, mainly because of deterioration in bridging between sand particles.

Objective: The objective of this study was to explore the safety, efficacy, economy, and other aspects of frequently-used antitumor Chinese patent medicine injections through a comprehensive evaluation of evidence-based medical research to provide scientific information and decision-making basis for drug selection, rational drug use, public awareness of safe drug use, and medical insurance. Materials and Methods: The names of five frequently used antitumor Chinese patent medicine injections were used as search terms, including the compound Sophora flavescens injection, Kangai injection, aidi injection, Kanglaite injection, and Brucea javanica oil emulsion injection. Relevant evidence-based medical research was extracted from the databases. A descriptive evaluation was conducted, and the Markov model was used for the cost-benefit analysis. Finally, the above injections are ranked by comprehensive scores using the multi-criteria decision analysis and Delphi method. Results: The five injections had their own advantages in enhancing the effectiveness of anti-tumor treatments, improving the quality of life for cancer patients, and reducing the incidence of adverse reactions. From the perspective of economy and other attributes, compound S. flavescens was superior to B. javanica oil, aidi, Kangai, and Kanglaite. After a comprehensive evaluation of the above five injections, the compound S. flavescens injection received the highest score. Conclusions: Compound S. flavescens, Kangai, aidi, B. javanica oil, and Kanglaite have their own advantages in effectiveness and no significant difference in safety. Compound S. flavescens injection has the highest comprehensive score. Clinical attention should be paid to monitoring the initial stage of medication and special groups.

提高生态福利绩效是实现经济可持续发展、推进经济社会全面绿色转型的必要条件。本文围绕居民福利和生态消耗构建了能够量化评估中国生态福利绩效的方法,并在此基础上利用ST-LMDI模型对中国各省份及8个经济区的生态福利绩效进行时间分解和空间分解,拓展当前对生态福利绩效驱动因素分解的研究。研究结果表明,2001—2020年中国生态福利绩效呈现出先升后降的变动趋势,空间上具有显著的地区差异性。其中沿海地区社会经济结构和民生性财政支出具有更高优势,生态福利绩效处于较高水平,且表现出空间溢出效应。引入社会效益、经济效益、人口分散度、建成区人口密度、城市化规模和生态可持续能力6个因素探索其对生态福利绩效的驱动作用,发现时间和空间分解结果表现出显著差异。基于时间分解结果,经济效益和城市化规模为促进生态福利绩效提升的主要因素,人口分散度是抑制生态福利绩效增加的主要因素。但从空间分解结果看,决定各省生态福利高于均值的驱动因素在不同时期内存在区域差异和动态变化特征。综合考虑时间和空间分解结果,全面把握经济增长、生态保护和居民福利提升的关系,有助于为地方政府制订并实施差异化政策提供参考。

语言中的非言语发声如笑声、叹息、抽泣等,称为功能性副语言,对情感表达起重要作用,但现有研究很少考虑多种功能性副语言在一种情感中的协同作用.针对该问题,提出了融合功能性副语言比例系数(functional paralanguage proportion coefficient,FPPC)的情感识别系统.首先,提取能体现多种功能性副语言在情感语句中出现的频率快慢和持续时间长短的FPPC特征;然后,搭建基于注意力机制的集成学习(attention stacking)为不同的基分类器赋予不同权重,并对FPPC特征进行训练;最后,通过自适应熵权重决策融合方法将传统语音情感识别与基于FPPC特征情感识别进行融合.实验结果显示,融合了FPPC特征后的情感识别结果提高了16.84%,证明融合FPPC特征能有效提高系统整体识别率.
