:为预测葡萄花油层的油藏分布 ,综合应用岩心、录井、测井、地震及粒度分析资料 ,采用沉积学、地震地层学方法 ,阐明了松辽盆地南部海坨子地区葡萄花油层沉积微相特征 .葡萄花油层在研究区西部逐渐减薄、尖灭 ,乃至缺失 .沉积区由西向东依次发育河流相、三角洲相、湖泊相 .西部地层尖灭线附近的河道砂发育区可形成砂岩尖灭地层圈闭 ,是本区葡萄花油层的优选勘探目标
In order to predict the reservoir distribution of Putaohua reservoir, the authors used sedimentology and seismic stratigraphy methods to comprehensively apply the data of core, logging, logging, seismic and particle size analysis to elucidate the depositional micro-deposits of Putaohua oil layer in the sea Tuotu area, southern Songliao Basin The characteristics of the Putaohua reservoir are as follows: the Putaohua reservoir is gradually thinned, pinned out or even missing in the west of the study area.The river facies, the delta facies and the lacustrine facies are successively developed from west to east in the sedimentary area.The sandstone development zone near the pinnacle of the western strata can form sandstone Pinch off the formation trap, is the region of Putaohua preferred exploration targets
