摘要
利用高分辨率层序地层学、沉积岩石学等方法对研究区PⅠ—SⅡ、SⅢ等目的层位各个发育时期的湖岸线位置及其演化规律进行了分析和研究,总结了湖岸线摆动带内砂体的沉积演化规律及湖岸线附近岩性油气藏形成的有利条件,为研究区油田进一步挖潜提供了方向和建议。
The Daqing placanticline in northern Songliao Basin is composed of seven anticlines,including,from north to south,Lamadian,Sartu and Xingshugang Oil Fields.The target horizons in individual oil fields are significantly made up of PI,SII and SIII oil measures.The present paper deals with the location and evolution of the lake strandline in individual target horizons during individual stages,sandstone evolution within the lake strandline and favourable conditions for the accumulation of the lithologic oil pools on the basis of high-resolution sequence stratigraphy and sedimentary petrography.
