松辽盆地泉四段扶余油层发育浅水湖泊三角洲相和浅水湖泊相,沉积构造环境属于闭塞浅水坳陷湖盆,其层序特征类似于稳定克拉通盆地层序,也类似于缓坡被动大陆边缘型盆地层序,气候是控制陆相坳陷盆地层序形成的主要因素,三级层序内总体应表现为水进体系域-高位体系域构成1个完整的层序,而低位体系域不发育。
补充资料：湖盆
| 湖盆 lake basin 地表上汇集水体的相对封闭的洼地。形似盆状。湖盆成因有地壳运动形成的，如断陷湖盆、坳陷湖盆；还有外力作用形成的，如冰蚀湖盆、堆积湖盆等，此外也有人类经济活动形成的，如水库库区等。湖盆可以由5部分组成：湖岸、沿岸带、岸边浅滩、水下斜坡、湖盆底。湖泊面积的大小，湖盆地质条件和水流动态不同，湖盆的形态也有差异。研究湖盆的形态及其变化，有助于了解湖泊的起源、发展；湖泊的容积、湖水的理化性质和水文形势的变化。 |
