Title: Sedimentary characteristics of lacustrine carbonate rocks of the first member of Shahejie Formation in Banqiao-Beidagang area
Abstract: Carbonate reservoir develops well in the first member of Shahejie Formation in Banqiao-Beidagang area.The lithologies are mainly composed of biogenic limestone,oolitic limestone,dolomitic limestone and marlite,which formed carbonate-siliciclastic mixosedimentite not only in the component but also in the vertical sequence.The sediments in the north mainly have terrigenous clastic,and the mixosedimentite are composed of carbonate rocks,sandstone and mudstone,with the main component of lime-siltstone and lime-sandstone.the mixosedimentite in the south are formed by the carbonate rocks,mudstone and shale,with the main component of limestone shale.The sedimentary facies include shore-shallow lake,shallow lake,semi-deep lake,while the microfacies of biology bank and oolitic beach are more valuable for the oil and gas exploration.
