| 摘 要： | 应用高分辨率层序地层学理论，通过对各级基准面旋回的沉积动力学分析，依据１０口井岩心和１２５６口井测井资料，把松辽盆地三肇凹陷葡萄花油层划分为１个长期基准面旋回、２个中期基准面旋回、１２个短期基准面旋回,提出了葡萄花油层南部为同沉积构造抬升控制的中部缺失而非底部缺失的层序地层新格架。通过对短期基准面旋回内储层沉积特征、单砂体展布规律的研究，认为葡萄花油层主要储层水下河道砂体比原认识更连续，且延伸较远， 分流平原、内前缘相带南移达３６ｋｍ，这对深入认识该区油藏类型、聚油规律、特别是高含水期剩余油挖潜具有重要意义，对指导整个松辽盆地北部岩性油气藏勘探与开发具有重大影响。

| Abstract: | By using the high-resolution sequence stratigraphy theory,through depositional dynamic analysis,the cores of 10 wells and 1 256 well logging data,Putaohua reservoir of Sanzhao depression in Songliao basin is divided as 1 long-term base level cycle,2 medium-term base level cycles,12 short-term base level cycles,proposed middle flaw non-base flaw sequence formation new framework with the sedimentary structure lifting control in the south of Putaohua reservoir.Through the study of reservoir deposition character and single sandbody distribution law in short-term base level cycle,it is realized that the submarine river sandbody as Putaohua reservoir main reservoir course is continual than original understanding,also extends far away,the divergence plain,inner front facies belt south movement reaching to 36 km,this has important significance to know reservoir types in this area,is specially high watery time remaining oil extraction potential,has the significant influence on instructing lithological reservoir exploration and the development in the north block of Songliao Basin. |
