Implication of Water-Rock Interaction for Enhancing Shale Gas Production

Horizontal well drilling and multi-stage hydraulic fracturing technologies are at the root of commercial shale gas development and exploitation.During these processes,typically,a large amount of working fluid enters the formation,resulting in widespread water-rock interaction.Deeply understanding such effects is required to optimize the production system.In this study,the mechanisms of water-rock interaction and the associated responses of shale fabric are systematically reviewed for working fluids such as neutral fluids,acid fluids,alkali fluids and oxidative fluids.It is shown that shale is generally rich in water-sensitive components such as clay minerals,acidsensitive components(like carbonate minerals),alkali-sensitive components(like quartz),oxidative-sensitive components(like organic matter and pyrite),which easily lead to change of rock fabric and mechanical properties owing to water-rock interaction.According to the results,oxidizing acid fluids and oxidizing fracturing fluids should be used to enhance shale gas recovery.This study also indicates that an aspect playing an important role in increasing cumulative gas production is the optimization of the maximum shut-in time based on the change point of the wellhead pressure drop rate.Another important influential factor to be considered is the control of the wellhead pressure considering the stress sensitivity and creep characteristics of the fracture network.

Humanizing the Culture of Technology Teams: Strategies for Creating Healthier and More Productive Work Environments

With the advancement of technology, companies are increasingly dependent on technology teams to stay competitive. However, members of these teams often work in stressful and unhealthy environments, which can undermine their productivity and well-being. The humanization of the culture of technology teams is an approach that aims to create healthier and more productive work environments for team members, promoting balance between personal and professional life. Despite the importance of a healthy and productive work environment, many companies do not invest in strategies to humanize the culture of their technology teams. This can lead to high levels of stress, staff turnover and low productivity. The objective of this project is to identify effective strategies to humanize the culture of technology teams and create healthier and more productive work environments in digital companies. For this, factors such as management styles, psychological safety, human-centered development, individual beliefs and time and energy management will be analyzed. The project’s methodology will include a literature review on the subject and qualitative data analysis will be performed using a content analysis approach. This project will contribute to the advancement of knowledge about the humanization of the culture of technology teams in digital companies. The results can be applied to companies that want to create healthier and more productive work environments for their team members.

Application of the Industry-University-Research Education Model of“Works,Products,and Public Goods”in Design Majors Practical Courses in Colleges and Universities

One of the goals and requirements of China’s educational modernization includes prioritizing,guiding,and promoting the social service capabilities of universities.The teaching of practical courses in design majors in colleges and universities has long been plagued by problems such as being“out of touch with the market and social needs”and“ignoring the cultivation of creativity.”It fails to meet the goals and requirements of educational modernization.This article takes the“Fundamentals of Styling and Comprehensive Expression”course offered by the School of Design of Guangxi Normal University as an entry point to study the industry-university-research education method that combines“social service”with the teaching of design professional practical courses.It also attempts to improve“works,products,and public goods”through the establishment of the theoretical model of“product”and the analysis of practical application paths is carried out to solve the problems existing in the traditional teaching of the design major,enhance the social service capabilities of the design major,promote talent employment and industry and social development,and carry out teaching reform attempts.

新质生产力的分配向度:按劳分配与共同富裕之契合性论析

马克思按劳分配思想是内含对生产、分配、交换和消费环节规定的系统性思想,按劳分配是推动实现共同富裕的分配方式,但这一系统思想在现实中表现为生产端、分配端、交换端和消费端的“系统悖论”。按劳分配与共同富裕的理论兼容性与实践契合性应从描述性、规范性和系统性三重视野观照:现行两套分配体系边界的逐渐消融要求重新审视通往共富之路;按劳分配内蕴的革命性精神是当下推动共同富裕的根本精神;新质生产力发展下生产物化趋势与消费人化本性间的张力造成的“劳动”分配标准的弱化呼唤“新质”的分配标准。新质生产力的“颠覆性”影响要求对未来社会分配方式进行初步构建:在新质生产力的解放初期实行按“劳”分配+按“要素”分配;新质生产力深入发展阶段实行按“所有权”分配;在新质生产力的高度发达阶段实行按“需”分配。
