Abstract: Tight oil has currently made debut in worldwide non-conventional oil exploration, particularly in the North American region. China has made significant discoveries of oil from compact sandstone in recent years, which is extensively distributed in Songliao Basin, Ordos Basin and Sichuan Basin, showing a great potential for development. However, overall exploration and development as well as the related studies are still under the stage of preparation. It is quite possible that there will be a variety of opinions on the guideline of exploration in this area because the definition of tight oil is not unified in China. Focusing on the different tight oil conceptions, this article analyzes the tight oil conceptions put forward by foreign and domestic experts as well as the research institutions and determines the prevailing conception. In addition, it also makes briefings about tight oil reserves distributed both inside and outside China, elements of successful tight oil development, standards for selection of compact oil, exploration and development cost, and current conditions of development.
