摘要
综合利用岩心、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,阐述了松辽盆地南部海坨子地区萨尔图油层一砂组沉积微相特征.沉积相以湖泊相和重力流相为主.湖泊相主要为浅湖亚相,其微相类型有浅湖混合坪、泥坪及砂坪微相,以混合坪为主.重力流相识别出重力流水道和重力流扇2种沉积微相.重力流相发育区为本区油气藏形成的有利部位.
By comprehensively applying the data of core, logging, seismic and grain size analysis, the sedimentary microfacies of sandstone Group 1 in Sartu oil\|bearing layer of Haituozi area in the south of Songliao Basin are analyzed according to the sedimentology and seismic stratigraphy. The main sedimentary facies in this area include lacustrine facies and gravity flow facies. Lacustrine facies is mainly shallow lacustrine subfacies which containes mud\|flat, sand\|flat and mud\|sand mixed\|flat microfacies, and the dominant microfacies is mud\|sand mixed\|flat. Gravity flow channel and gravity flow fan microfacies are identified from the gravity flow facies. The regions developing gravity flow facies are favorable for oil pool formation.
