渭河盆地氦气资源勘探地震数据处理难点及对策
Difficulties and countermeasures of seismic data processing for helium resource exploration in Weihe Basin:Exemplified by Huazhou-Huayin area
摘要
Abstract
The Weihe Basin boasts abundant helium resources.Vigorously exploiting these resources is significant for national develop-ment and social progress.However,the complex geographical and geological conditions in the basin pose great challenges in seismic im-age processing and interpretation,severely hindering the identification of helium-rich natural gas traps and reservoir prediction.This study delved into the difficulties and challenges in processing the seismic data from the Huazhou-Huayin area.Based on the seismic ex-ploration objectives,an effective seismic data processing workflow was developed,along with targeted technical solutions,to address the difficulties in seismic data processing.The results of this study demonstrate that the quality of seismic data processing can be effectively improved using techniques,such as pseudo-3D tomographic static correction,global optimization residual static correction,multi-domain and multi-method serial denoising,multiple amplitude compensation and wavelet correction,and prestack time migration.These improve-ments provide critical technical support for the exploration and production of helium-rich natural gas in the exploration area,and valua-ble insights for seismic data processing for other regions within the basin.关键词
