摘要(Abstract)：

为了探索松辽盆地古龙地区湖相区的勘探潜力,寻找油气勘探新领域,通过详细的岩心观察和粒度分析,结合地震属性分析技术,发现古龙地区青山口组深湖区存在以重力流沉积为主的砂岩储层。根据重力流的搬运方式和流体性质不同,识别出滑动岩、滑塌岩、砂质碎屑流和浊流等4种类型沉积岩;按照重力流的空间分布和平面形态,划分出湖底扇型、斜坡扇型、断层切割型、水道型及离散型等5种类型的沉积体,其中以斜坡扇型和湖底扇型发育的砂质碎屑流最具勘探潜力。
In order to explore the exploration potentials of the lacustrine facies area in Gulong area of Songliao Basin and seek for the new exploration field,through careful core observation and the particle size analysis,integrated with the seismic attribute analyzing technique,the sandstone reservoirs taking the gravity flow sedimentation as the main form are discovered in Qingshankou Formation deep lake area.According to the different transporting ways of the gravity flow and liquid properties,four types of the sedimentary rocks are identified;sliding rocks,slumping rocks,sandy debris flow and turbidity/resedimented rocks;according to the spatial distribution and planar configurations of the gravity flow,five types of the sediments are classified;sublacustrine fan,slope fan,fault cut type,channel and discrete types.Among them,the sandy debris flow sedimentary rocks developed in the former two types show the most prospecting exploration potentials.
