    China Global Television Network's International Communication: Between the National and the Global
    (2018-01-23) Zhang, Yang; Mitchell, David; Sutherland, Richard; Sciban, Lloyd
    In the context of globalization and digitalization, international Chinese news media have developed rapidly over the past decade. One typical example is the rise of China Global Television Network, CGTN, an English-language news channel operating under the predominant state television broadcaster, China Central Television, CCTV. This project focuses on the production, distribution and consumption of CGTN. It addresses the question of "What roles does Chinese global television network play in China's integration into the globalization process?" Through a systematic analysis of current government policies, news programs of relative events, and extensive interviews of national and overseas audiences, the project describes some of the social impacts CGTN has or potentially may have on Chinese society in terms of globalization and its relation to national identity. As the study demonstrates, CGTN integrates both national and global elements in its branding strategies under the guidance of the Party state. The convergence of nationalism and globalization is the prevalent theme represented in its news and public affairs programs. In this way, CGTN frames a Chinese national identity that includes globalization while at the same time maintaining traditional national values. Based on an analysis of the responses, it appears that this news channel has more influence among its national audiences than its international audiences in terms of values and identities. The effectiveness of CGTN's international communication is still a challenging task.

    “Fracturing network+imbibition oil production” is a new attempt to effectively develop low-permeability tight reservoirs. Fracturing fluid is not only a carrier for sand carrying but also a tool in the process of imbibition. On the basis of imbibition experiments, combined with nuclear magnetic resonance and pseudo-color processing technology, this paper clarified the dominant forces of different types of pore-throat and quantitatively characterized the contribution of different levels of pore-throat to imbibition oil recovery. The results show that gravity is the main controlling force of imbibition for reservoirs with higher permeability. Fluid replacement mainly occurs in the early period of imbibition. Macropores contribute most of the imbibition recovery, mesopores have a weak contribution, and the contribution of micropores and pinholes can be ignored. For the reservoirs with low permeability, capillary force is the main controlling force of imbibition. Fluid replacement mainly occurs in the later period of imbibition. Macropores contribute most of the imbibition recovery rate, mesopores contribute a small part of the imbibition recovery factor, and the contribution of micropores and pinholes can be ignored. This paper clarified that macropores and mesopores are the main sources of the contribution of imbibition recovery efficiency, and oil content and connectivity are key factors for the imbibition recovery efficiency.
