摘　　要：石岩系是塔里木盆地西南地区的重要勘探领域之一,其油气资源丰富,但勘探程度很低。根据对能独立反映沉积环境的某些特征单因素(厚度、结构组分、岩相、岩性比率、岩石学特征等)的分析,并结合地球化学指标,在对本区石炭系石油地质条件研究的基础上,指出了4个有利的油气勘探地区,即巴楚隆起西端、玛扎塔克断裂带—海米—罗斯断裂带、麦盖提斜坡的北缘和南缘推覆体上盘,并提出了相应的勘探对策。Carboniferous strata are important exploration field in the southwestern Tarim basin. Oil-gas resource is very rich, exploration work is insufficient. Combined geochemistry index, the article analyses some characteristic factors, i.e., which can reflect sediment environment independently. The characteristic factors are thickness, fabric form, lithofacies, lithology ratio andlithology characteristic. On the basis of research of the oil-gas geologic conditions, the most favorable areas for oil-gas exploration are indicated, i.e., the western end of Bachu uplift, Mazatake-Haimi-Luosi faulted zone, the northern edge of Meigeqi slope and the overthrust plate of southern edge. And the article brings forward the correspondence countermeasures.
