摘　　要：以岩心、测录井等资料为基础,结合沉积相及前人研究成果,对苏家屯地区火石岭组碎屑岩储层砂体进行了研究,研究表明:苏家屯地区火石岭组主要发育火山岩相和扇三角洲相,典型储层砂体主要为火石岭组砂砾岩。通过分析,火石岭组储层主要为低孔、特低孔特低渗孔隙-裂缝型储层;岩相和岩性对储层发育起着重要的控制作用,其中,扇三角洲前缘水下分流河道和细砂岩对储层物性控制作用最佳;微裂缝和次生孔隙的发育利于产能的提高,充填作用、压实作用、胶结作用不利于产能提高。Based on the core and logging data,combined with the sedimentary facies and previous research results,the clastic reservoir sandstone of the Huoshiling Formation in the Sujiatun area was studied.The study shows that the Fushiling area in the Sujiatun area The group mainly develops volcanic facies and fan delta facies.The typical reservoir sand bodies are mainly the Huishiling Formation glutenite.Through analysis,the Fushiling Formation reservoirs are mainly low-porosity,ultra-low pore ultra-low permeability porefracture reservoirs;lithofacies and lithology play an important role in controlling reservoir development,among which,the fan delta front is underwater.The distributary channel and fine sandstone have the best control effect on reservoir physical properties;the development of micro-cracks and secondary pores is conducive to the improvement of productivity,and the filling,compaction and cementation are not conducive to the increase of productivity.
