石岩系是塔里木盆地西南地区重要的海相烃源岩和储集岩地层,油气潜力很大,但目前仅发现了1个气田、1个油田和2个油藏,勘探程度很低。本文在岩相古地理和地震地层学岩性岩相研究的基础上,对本区石炭系的烃源岩和储集岩的类型、分布及其与沉积环境的关系进行了研究,对盖层性质和分布,尤其对石炭系经过多次大的构造变动后所形成的油气潜景区进行了较深入的探讨,并指出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、南缘推覆体上盘。同时指出了各有利地区的勘探对策。

Carboniferous strata are important marine source rocks and reservoir rocks in the southwestern Tarim basin. Oil and gas potential there is very rich. Nevertheless, due to insufficient exploration work, only one gas field, one oil field and two oil pools have been found. On the basis of researches of lithofacies-paleogeography and seismic stratigraphy, the authors made detailed investigation into the types and distribution of Carboniferous source rocks and reservoir rocks in relation to their sedimentary environments, the nature and distribution of regional and local capping beds, and especially the potential oil and gas area formed as a result of many times of important tectonic movements. Four most favorable areas for oil and gas exploration were delineated, i.e., the western end of Bachu uplift, Mazatake-Haimiluosi faulted zone, the northern edge of Meigeqi slope, the overthrust plate of the southern edge.
