琼东南盆地深水油气勘探中复杂地震多次波特征及压制对策
COMPLEX MULTIPLES AND THEIR SUPPRESSION STRATEGY IN DEEP WATER SEISMIC EXPLORATION IN QIONGDONGNAN BASIN
摘要
Abstract
Exploration and discoveries have confirmed that oil and gas are rich in deep water areas.However,complex multiples seriously affect the signal-to-noise ratio of the dataset and the quality of images in the middle to deep water areas.Recently,multiple technology based on the theory of multiple wave has rapidly developed.Comparing to the traditional multiple suppression technology including predictive deconvolution and 2D filtering and so on,it requires less prior information and may predict multiple models to attenuate multiples by matching subtraction so as to better preserve the primary amplitudes.However,there are still many difficulties in actual data processing,for examples,losing near offset in shallow water region and the influence of water bottom topography.There need integrated approaches to eliminate multiples with complex wave field.In this paper,we studied the model prediction for multiple attenuation and summarized the differences and application of multiple models.关键词
