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.
