Abstract：The Carboniferous-Permian residual strata in the northern Jiyang Depression of the Bohai Bay Basin has become one of the key areas for oil and gas exploration in recent years. In order to clearly understand the distribution characteristics of sedimentary facies and sand body in ancient buried hill reservoir,the sedimentary characteristics of the Carboniferous-Permian in the northern Jiyang Depression of Bohai Bay Basin have been systematically studied based on the stratigraphic division and correlation,well logs,sedimentary structures,lithology and sedimentary sequences. Results show that the thickness of the Carboniferous-Permian strata in the buried hill area has changed rapidly,and the Shiqianfeng Formation have been almost eroded. During the Carboniferous-Permian period,the study area underwent the evolution process of alternating continent-marine facies,continent-marine transitional facies and river facies. During the Benxi and Taiyuan Formations depositional period,the lagoon,tidal flat and barrier island facies developed in the study area. The delta facies developed in the Shanxi Formation depositional period,and it was mainly characterized as the delta plain deposits,which can identify the detailed facies such as distributary channel,interdistributary channel,natural levee and peat swamp. During the Upper and Lower Shihezi Formations,braided river facies was the dominated sedimentary facies and it was divided into channel bar,channel lag deposits and floodplain microfacies. The sand bodies in the Benxi and Taiyuan Formations are spotted distributed under control of the evolution of sedimentary environment. The sand bodies of Shanxi Formation,the Lower and Upper Shihezi Formation are distributed in a banded strip near NE to SW direction. The studies on the sedimentary facies and distribution law of sand bodies in the buried hills of the northern Jiyang Depression can provide key geological basis for oil and gas exploration in the ancient buried hills.
