摘要
在吉林探区,随着勘探的深入和技术的发展,古河道作为良好的油气储集体,其物性好、产能高的特点成为岩性勘探的首选目标。但受地震资料品质的限制,古河道的识别始终是地震资料解释中的难点问题。从长春岭地区泉四段实际地质情况出发,应用地震属性分析、分频扫描、特征反演、地震相分析、可视化雕刻等多种储层预测技术手段联合作业,对古河道识别方法进行仔细研究和筛选,探索出适合于吉林探区古河道识别方法的工作流程。为开发产能建设和勘探井位部署提供技术支持。
In Jilin Oilfield,with the development of exploration technology,the old channel evolves into the preferred target for lithologic exploration because of its characteristics like good physical properties and high productivity.But channel identification is still difficult in seismic interpretation because of the limitation of seismic data quality.In view of the actual geological condition of the fourth member of Quantougou Group in Changchunling Region,based on seismic attribute analysis,frequency scanning,characteristics inversion,seismic facies analysis,and visualization sculpture,the methods for old channel identification are carefully selected.The working flow of the method applicable to oil channel identification in Jilin Oilfield is figured out,offering technical support for the development of capacity-building and deployment of exploration wells.
