| 摘 要： | 利用井-震结合、地层对比、沉积相及古地貌分析等方式识别沟谷-坡折带,重点分析了沟谷-坡折带特征及对储层分布的控制作用.研究表明:松辽盆地西斜坡早白垩世发育的两极挠曲坡折带在平面上呈北东向展布;沟谷顺物源分布,垂直于坡折带走向;在基准面旋回变化过程中,沟谷-坡折带对沉积物的体积分配和相分异有特定的控制作用,进而与储层的分布有着密不可分的关系;沟谷是控制水系和沉积物搬运的通道,坡折带是沉积物卸载的场所,沟谷-坡折带体系控制了沉积物的类型和平面分布.

| Abstract: | Through comprehensive study on well data and seismic profile,stratigraphic collection,sedimentary facies and palaeo geomorphology analysis,the valley-slope break zone was identified,and characteristics of the valley-slope break system and its control over reservoir distribution were emphatically analyzed.The results show that the two flexural slope breaks spread in NE direction in the western slope of Songliao Basin during the early Cretaceous period and the valley is vertical to the strike of slope break z... |
