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.
