摘　　要：通过层序地层学的划分与对比,将塔中地区石炭系划分为4个沉积层序,该区石炭系沉积相主要以滨海相沉积为主,在滨海相沉积背景下出现了海滩与潮滩两种不同的沉积体系此外还发育有台地相、三角洲及辫状河三角洲沉积体系等,沉积相按其发育时间和平面上的展布特征,可以归为4类沉积体系组合:海滩(前滨、临滨)-局限台地组合、(潟湖-)潮滩(潮上、潮间及潮下)-局限台地组合、辫状河-(辫状)三角洲-局限台地组合、台地潮坪-局限台地-开阔台地组合,沉积环境经历了滨海—局限台地—滨海—局限台地的演变过程,发育砂岩和碳酸盐岩两类储层,并发育有良好的区域性盖层。An investigation of sequence stratigraphy shows that the carboniferous system in central-tarim can be divided into 4 sedimentary sequence, the sedimentary facies are dominated by littoral facies, two different sedimentary system, fore(?)hore and tidal bank,developed under the littoral facies sedimentary background, in addition, plateau facies and delta facies sedimentary system also developed, according to their developing age and their distribution, sedimentary facies can be divided into 4 type sedimentary system association, sedimentary environment underwent the evolution from littoral facies to restricted platform facies, littoral facies to restricted platform facies, the carboniferous system in central-tarim area of tarim basin develop two type reservoir bed: sandstone reservoir and carbonate reservoir and develop a good territorial capping bed.
