| 摘 要： | 在准噶尔盆地吉木萨尔凹陷东斜坡开展高分辨率层序地层学研究，识别出三种准层序类型，对应三种短期基准面旋回:基准面上升型、基准面下降型、基准面下降半旋回和上升半旋回两部分构成的复合型准层序。两种中期基准面旋回:中期基准面下降旋回，由多个进积式的短期旋回组成；中期基准面上升旋回，地层堆叠样式则呈退积结构。研究区梧桐沟组可划分为5个准层序组（中期基准面旋回），自下而上依次为 S1、S2、S3、S4、S5，基准面上升期形成S1、S2，基准面下降期形成S3、S4、S5。吉7井和吉17井梧桐沟组出油砂层属于不同的准层序组，成因不同，因而不是同一砂组。

| Abstract: | By means of high-resolution sequence stratigraphy study on Permian Wutonggou Formation reservoir in Jimsar Sag of Junggar Basin,we identified three parasequence types corresponding to three short-period base level cycle modes:base level rising parasequence,base level fallng parasequence,base level rising and falling half cycle composite parasequence.And two middle-period base level cycles are discriminated.The formation of middle base-level falling cycle is made up of mutli-prograding short-period cycles whereas middle base-level rising cycle stacking mode presents retrograding structures.The Permian Wu Tong Gou Formation can be classified 5 parasequence sets(corresponding to 5 middle-period base level cycles)in this area,which is S1,S2,S3,S4,S5from bottom to top.S1,S2are formed during rising stage of base-level while S3,S4,S5 formed during falling stage.According to the research conclusions we reckon the two petroliferous sand beds of Well Ji 7 and Well Ji 17 are not pertained to a same sand set as its forming reason is different.So we have resolved the practical question.One stratigraphic trap and five lithologic traps are recognized by the theory of high-resolution sequence stratigraphy and the prospecting targets are offered. |
