【摘要】 通过对青东5地区地震资料特点进行详细的分析和研究,本文采用二次定位、互相关、模型法振幅调节和叠前时间偏移等关键技术,对拖缆漂移、不同震源及检波器差异和过渡带振幅能量异常现象进行了相应的研究和有针对性的处理,最终取得了较好的成像效果,为该区域油气勘探开发提高了有利的技术援助。更多还原

【Abstract】 Based on the characteristic of seismic data from Qingdong 5 exploration area, relevant techniques such as secondary location, cross correlation, amplitude adjustment by model method, prestack time migration, and so on, have been applied in the research and processing for towing cable drift, difference between various seismic sources and geophones and amplitude energy anomaly of transition zone. Good resulting images have been obtained in the end. and the reseach results can provide strong technical helps for exploration and development in Qingdong 5 exploration area.更多还原
