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.

摘要： 目前,致密油已成为全球非常规石油勘探新亮点,北美地区表现尤为突出;我国近年在致密砂岩油有重大发现,在松辽、鄂尔多斯、四川盆地等地广泛分布,显示了巨大的开采潜力,但总体勘探开发和相关研究仍处于准备阶段。由于国内对致密油定义不统一,将来很有可能在勘探的指导思想上有不同的取向。针对致密油概念比较混淆的状况,对国内外学者或研究机构提出的概念进行了整理分析,确定了主流概念,并对国内外主要致密油分布、资源量、致密油开发成功的要素和主要筛选标准、勘探开发成本、发展现状进行了介绍。
