西丁家地区地震反射异常体识别与分布研究
|
摘要
松辽盆地梨树断陷西丁家地区下白垩统为深水环境下发育的沉积地层。通过对研究区地震剖面的精细地层解释,发现在不同层系中,如沙一段和营三段,存在多种地震反射异常体且数量可观。这些异常体多数为浊流及生物沉积作用下形成的,在地震剖面上呈长条状、下切状和透镜状等外部反射特征。在对这些地震异常体特征识别和分类的基础上研究发现,本区的地震异常与岩性油气藏的形成有着密切的关联,且大部分地震异常体还未进行钻探。通过对异常体的地震追踪和解释对其进行识别和分布研究,为西丁家地区下一步岩性油气藏的勘探和开发提供新的思路。
The lower cretaceous strata of Xidingjia Area,Songliao Basin is dominated by deep-water deposits.Through the correlation and interpretation of seismic profiles in the researched area,we found that there are many kinds and amounts of seismic anomaly bodies in different layer series,such as Sha 1 Member and Ying 3 Member.The majority of these anomaly bodies are formed by turbidity current deposit and biogenic deposit,and they display external reflection characteristics of banding,downward cut and lenticular.Based on the study of feature classification of seismic anomaly bodies,we found that there are close correlations between seismic anomaly bodies and lithological subtle reservoir in this area and most of them have not been drilled.Therefore,it means good oil and gas prospects.Identification and distribution research with seismic trace and interpretation of anomaly bodies,can provide new ideas for further exploration and development of lithological subtle reservoir in Xidingjia Area.
