摘　　要：孔雀河地区位于塔里木盆地东北缘,有较好的油气勘探前景.依据地震地层学、层序地层学的方法原理,以地震资料为基础,结合钻井、地表露头资料分析,认为该区寒武—奥陶系主要发育台缘斜坡相、浅水陆棚相、深水陆棚相、陆棚斜坡相、半深海盆地相、深海槽盆地相、大陆坡相带及海底扇亚相,在对沉积相序、沉积相平面展布、沉积演化等沉积体系研究基础上,综合考虑了该区的古地理环境、沉积相平面组合规律及控制因素,建立了孔雀河地区寒武—早奥陶世的沉积相模式。Kongquehe region is located in the northeast of Tarim Basin, with oil and gas exploration foreground. According to the methods and principles of seismic stratigraphy and sequence stratigraphy, based on seismic, well and outcrop metarials, the types and characteristics of sedimentary facies were discribed as follows: platform margin slope, shallow continental shelf, deep continental, shelf margin slope, deep sea basin, continental slope and submarine fan. On the basis of sedimentary facies sequence, sedimentary facies distribution and sedimentary evolution, considering palaeogeography environment, assembled disciplination and controlling factors of sedimentary facies, sedimentary pattern of Cambrician-Early Ordovician was built in Kongquehe region. This paper provides a foundation for the further research and oil exploration of the study area.
