陈家庄地区浅层真假亮点识别技术
|
摘要
陈家庄地区浅层气藏丰富,以浅层气识别为对象,亮点技术的应用存在陷阱。为了在勘探开发中识别出真假亮点,研究地震资料上亮点形成机制,基于地震正演模拟分析,气层与水层在叠前道集以及不同频率地震剖面上均具有不同的响应特征,分别从叠前和叠后两方面,应用AVO和分频技术进行真假亮点的识别,均取得了较好的应用效果。
Chenjiazhuang area is abundant with shallow gas reservoirs.However,the application of bright spots technology is not perfect for the recognition of shallow gas.In order to identify true and false bright spots in the process of exploration and develop ment,the research on the formation mechanism of bright spots of seismic data was conducted.Based on the analysis of seismic for ward modeling,it was found that the response characteristics of gas layer and water layer in pre-stack gathers and different-fre quency seismic profiles were different.From the two aspects of pre-stack and post-stack,the application of AVO and spectral de composition technology achieved good results in identifying true and false bright spots.
