在前人认识的基础上,利用地震、测井、地化、岩心等资料,通过对松辽盆地北部英台大安地区青一段沉积相进行精细研究,指出主要为半深湖到深湖相带,在工区西部存在滨浅湖相带及湖底扇,同时明确英台地区湖底扇分布规律,发现除英台西部湖底扇外,还存在中部湖底扇,含沙量较高,且规模较大。
On the basis of previous knowledge, through the careful study of the sedimentary facies in the first member of Da’an, Yingtai, northern Songliao Basin, using the data of earthquakes, logging, geochemistry and core, it is pointed out that the sedimentary facies are mostly semi-deep lacustrine to deep lacustrine facies . In the western part of the work area, there are the shore-shallow lacustrine facies and the sublacustrine fan. At the same time, the distribution rules of the sublacustrine fan in the area of Yingtai are clear. It is found that in addition to the sublacustrine fan in the western part of the Yingtai station, there is also the central sublacustrine fan with high sediment concentration and large scale.
