| 摘 要： | 松辽盆地南部西部斜坡带含油层系已成为吉林油田近期勘探方向。西部前缘带的三角洲前缘沉积微相包括前缘席状砂、远砂坝、三角洲前缘分流河道和河口坝等。通过岩性、沉积构造、岩石结构、测井特征、粒度分析和砂地比等综合分析，探讨了各三角洲前缘沉积微相的识别标志。应用三角洲前缘沉积微相的识别标志，完成青一段二砂组沉积微相平面分布图。分析出有3个物源：西部物源、西南物源和西北物源；席状砂、河口坝和远砂坝等三个微相带为油气聚集有利相带。

| Abstract: | Oil bearing layers on west slope zone in southern Songliao Basin has been becoming exploration orientation of Jilin Oilfield recently. There are mat-shape sand,far bar,subwater channel and channel bar micro-facies for delta-front on west front belt. Distinguishing marks for sedimentary micro-facies of delta-front of middle oil-bearing layers on west front belt in southern Songliao Basin are discussed synthetically in lithology,sedimentary structure,texture,logging,grain size analysis and sand-formation proportion. Applying the distingui- shing marks,the distribution map on sedimentary micro-facies of second oil sand set of first part Qingshankou Formation has been made. There are three sediment sources:west,southwest and northwest souros. Mat-shape sand,far bar,subwater channel and channel bar micro-facies are facies to oil and gas confluence. |
