On the basis of re-recognizing the geological characteristics of the reservoir in Well A, using laboratory experiments, statistical analysis and other methods, systematically carry out injection and production dynamic analysis in Well A, analysis of damage mechanism of water injection wells, analysis of reservoir damage factors and reservoir Research on protection technology, put forward suggestions on reservoir protection technology and augmented injection technology for well An area. Mixed injection of water is likely to cause insoluble scaling and lead to blockage of water injection pipelines and reservoir pore throats. Working fluids that are not compatible with the formation enter the formation and also cause blockage of the reservoir. Therefore, oil reservoirs must not only pay attention to reservoir protection measures during water injection development It is also necessary to strictly control the quality of the injected water and strictly select additional injection fluids to effectively protect the reservoir and carry out long-term and efficient water injection operations.
President Hu Jintao set the transformation of economic development mode as the nation's new economic strategy in 2007 to replace the one formulated in 1995. This paper holds that the new economic development mode is essentially dependent on the innovative activities of entrepreneurs. By analyzing the inner connection between innovation and entrepreneurship and the transformation, this paper illustrates the important role of entrepreneurship in the transformation and suggests some measures for China to foster entrepreneurship.
After 30-year economic reform, the relationship between enviornment, resources, population and economic development is becoming increasingly tense. Chinese government has recognized the problem and found out a best possible solution--to transform the development mode from relying on agriculture and manufacture to on the tertiary industry, or service sector. This essay analyzes the current status of service economy in China, points out the problems of China in developing service economy and finally offers some policy suggestion for China to develop service economy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
