摘　　要：利用岩心、测井、录井及地震资料,采用自然伽马曲线波形指示模拟反演、地层切片、叠后频率域油气检测属性等方法,进行前哨地区三工河组二段一砂组沉积相类型识别划分、储层砂体预测及含气性检测,识别刻画有利储层发育区。结果表明:前哨地区三工河组二段一砂组发育三角洲前缘亚相沉积,包括水下分流河道、水下分流间湾、席状砂沉积微相。研究区发育北向和东北向3条分支河道,其中东北向2条分支河道体系交汇于QS2—MO16井区,河道砂体发育,砂体厚度大,呈条带状由东北向西南延伸。识别4处优质储层发育区,分别位于QS1、QS2、QS7井区及QS13井以东区域,总面积约为62 km^(2)。该结果可为前哨地区油气勘探评价部署提供指导。Using the core,logging,recording and seismic data,the methods based on Gamma ray curve waveform indication simulation,stratigraphic section and post-stack frequency domain oil and gas detection attributes were applied to identify and classify the sedimentary phase type of the first sand group of member 2 of Sangonghe Formation in Qianshao Area,predict the reservoir sand body,detect the gas content,and identify the favorable reservoir development area.The results showed that the deltaic foreground subphase sedimentation,including submerged divergent channels,submerged divergent interbay,and matted sand sedimentary microphase,was developed in the first sand group of member 2 of Sangonghe Formation in the Qianshao Area.Three branch channels in the north and northeast directions were developed in the whole area,among which two branch channel systems in the northeast intersected in the QS2-MO16 well area,and the sand body of the channel was developed with large sand thickness and extends in a strip from the northeast to the southwest.The total of four high-quality reservoir development areas were identified,which located in the QS1 well area,QS2 well area,QS7 well area and the area east of QS13 well,with a total area of 62 km^(2).The research results could provide guidance basis for the next oil and gas exploration and evaluation deployment in the Qianshao Area.
