| Abstract: |
| 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. |
| Key words: lake strandline evolution lithologic oil pool sandstone distribution |
