Reflections on Scientific and Technological System Restructuring Fu Cheng-de 2010, 29(3): 24-28.  DOI: 10.3969/j.issn.1002-302x.2010.03.004 Abstract ( )   PDF (1522KB) ( )   Scientific and technological system restructuring has undergone a very long process and now is further deepened. Referring to some instances of petroleum companies, the author in this paper presents his view on the connotation and denotation of scientific and technological system. Taking foreign petroleum companies for instance, the author puts forward some opinions about how to deepen the reform of petroleum technology in the future. He believes that "scientific and technological system is a matter of culture, a collection of organizational systems, management systems, and operational mechanism of scientific and technological activities", the soul of technological innovation, and the key to bring about more achievements and cultivate more qualified personnel. He also suggests that scientific and technological work of enterprises be carried out at places nearest to production sites.

Global Distribution and Advances in Production Technologies of Oil Shale Yi Xi, Zhang Xin, Qu Ze-yuan, Wang Zhi-hua 2010, 29(3): 62-74.  DOI: 10.3969/j.issn.1002-302x.2010.03.013 Abstract ( )   PDF (1502KB) ( )   In the past few years, the United States, which has the largest and most concentrated deposits of oil shale in the world, and several other nations which also have significant oil shale resources including Estonia, Israel and Turkey pay high attention to explore and develop oil shale resources. Several factors have contributed to this, including soaring oil prices, emerging recovery technologies, increasing global demand for liquid hydrocarbons and the steady decline in conventional oil resources. Since 2006, more than 25 petroleum companies have released new oil shale technologies successively. Proceeding from the perspectives of oil shale production technology and promoting its commercialization, this paper introduces such advanced oil shale production technologies as reducing water use, improving energy efficiency, emissions management, reducing surface impact, use and disposal of waste shale, and effective groundwater protection, indicating that it is feasible to produce oil by use of oil shale technically and economically.
