摘　　要：对准噶尔Z2井三叠系各组的岩性、电性特征进行了详细解释与描述,对各组的孢粉、大孢子组合特征展开了讨论,提出了该井三叠系地层划分为自碱滩组、克拉玛依组和百口泉组,且将其与邻区钻遇的三叠系进行了横向及纵向对比。在此基础上,通过对测、录井资料的精细解释,并借鉴前人的区域沉积相研究成果,探讨了该区三叠纪沉积环境。The Triassic lithologic and electrical characteristics of Well Z2 from the central Junggar Basin,Xinjiang, northwestern China are described and interpreted. Based on the assemblages of sporopollens and megaspores, the Triassic succession of Well Z2 is subdivided and correlated with adjacent wells. The Triassic sedimentary environment is interpreted on the basis of well logging data and previous studies on regional sedimentary facies.
