摘　　要：对国内外相关文献资料进行了系统调研,并对准噶尔盆地“低品位”储量进行了明确定义和分类。研究表明,“低品位”储量在我国勘探开发中占有举足轻重的地位。依据“低品位”储量定义,计算新疆油田2005年底“低品位”储量占已探明储量的66.99%,其中已开发的“高品位”稀油储量因含水率上升或井产量的下降而演变成的“低品位”储量占已探明储量的8.8%.通过对低品位储量的各种分类和研究,准噶尔盆地“高品位”储量主要分布在克拉玛依、陆梁、彩南和红山嘴等油田的三叠系和二叠系,准噶尔盆地腹部、南缘也是继续寻找“高品位”储量的主要区带。The systematic investigation of the relevant literature on low-grade reserves at home and abroad is made, and the definition and classification of the ＂low-grade＂ reserves in Junggar basin are conducted accordingly. Study shows that the low-grade reserves play a significant role in petroleum exploration and development in China. In terms of this definition, it is estimated that the low-grade reserves in Xinjiang Oilfield Company account for 66.99% of the total proven reserves by the end of 2005, of which the produced ＂high-grade＂ thin oil reserves that turned into the low-grade reserves due to water cut increase or production rate decline account for 8.8%. Such high-grade reserves are mainly distributed in Triassic and Permian systems of Karamay, Luliang, Cainan and Hongshanzui oilfields. In addition, the major areas for further searching for the ＂high-grade＂ reserves could locate the hinterland and southern margin of Junggar basin.
