摘　　要：以层序地层学、储层地质学、沉积岩石学理论为指导,结合岩心观察、薄片鉴定、物性分析、X-衍射等测试方法,对松辽盆地北部G地区葡萄花油层储层特征及其主控因素进行了深入的剖析。研究表明,区内葡萄花油层岩性主要为长石岩屑砂岩和岩屑长石砂岩,结构以细砂岩、粉砂岩为主;孔隙类型主要为残余原生孔隙;依据岩石结构、孔隙类型及埋藏深度将储层划分为4类;碎屑粒度、填隙物、压实作用及沉积相带为区内储层的主要控制因素。Based on sequence stratigraphy,reservoir geology and sedimentary petrology,Combined with core observation,thin section identification,physical property analysis,X-diffraction and other test methods,the characteristics and main controlling factors of Putaohua Reservoir in G Area of Songliao Basin were analyzed.Research shows that Putaohua Reservoir in the area is mainly composed of feldspathic lithic sandstone and lithic feldspathic sandstone,the rock structure was mainly composed of fine sandstone and siltstone.The pore types are mainly residual and primary pores.According to the rock structure,pore type and burial depth,the reservoir can be divided into 4 types,the main controlling factors of reservoir are clastic grain size,interstitial material,compaction and sedimentary facies.
