Abstract

Based on seismic,palaeontological, sedimentary and logging data, strata frequency of Shahejie formation in Qibei seg, Huanghua depression was studied by means of sequence stratigraphy,and the formation was divided into two sequences,Ⅰ(3rd member of the formation and Ⅱ(2nd and 1st members of the formation). Each sequence was further divided into three system tracts, low stand, transgressive and high stand system tracts. The characteristics of the system tracts were described in detail, and prospective factes tracts and zones for oil/gas accumulation in the seg were pointed out in the paper.
