西丁家地区地震反射异常体识别与分布研究
Identification and Distribution Investigation of Seismic Reflection Anomaly Bodies in Xidingjia Area
摘要
Abstract
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.关键词
