摘　　要：BY 凹陷西南部地区储层发育,区内钻探程度已较高。为继续寻找具有圈闭条件的薄层砂体,从钻井资料出发,充分利用测井曲线的信息,选择有利储层,通过合成地震记录对地震剖面进行标定和横向追踪,圈出有利薄砂层的分布范围,计算出其分布面积和厚度。钻探结果表明,在扇三角洲前缘席状砂地带,可寻找具有圈闭条件的薄层砂体。There are many reservoirs and exploratary wells in the southwestern BY sag.In order to find out thin-bedded sandbodies,based on well-log information and synthetic seismogram,seismic reservoirs are demarcated and traced,and the range of beneficial reservoirs is determined,the distribution area and thickness of the reservoir are calculated.The drilled result shows that beneficial thin-bedded sandbodies will be found out in the deltal-fan front sheet sand.
