摘要： 利用层序地层学原理和研究方法对塔北隆起的侏罗系、白垩系、下第三系、上第三系吉迪克组（N1j）进行层序及体系域的划分。重点对四套储层（侏罗系底砂岩、白垩系大套砂岩、下第三系底砂岩、吉迪克组底砂岩）,两套盐膏盖层（下第三系上部盐膏层、吉迪克组盐膏层）进行研究,确定其分布范围,对其沉积特征做出合理解释,对储盖组合做出合理评价,指出有利的勘探领域和勘探目标。

Abstract: Sequence and system tract were divided in Jurassic, Cretaceous, Paleogene and Jidike formation of Neogene in Tabei uplift based on sequence stratigraphy principle and its study method. Four sets of reservoir rocks, i. e. sandstone at the bottom of Jurassic, extensive Cretaceous sandstone, sandstone at tlie bottom of paleogene and sandstone at the bottom of Jidike formation, and two sets of salt-gypsum caprocks, i. e. Lower Paleogene salt-gypsum bed and salt-gypsum bed of Jidike formation were emphaticliy studied, including determination of their extent, proper interpretation of their sedimentology, valid assessment of reservoir-caprock assemblage, and selection of favorable exploration area and target.
