在海洋地震资料处理中多次波识别与去除技术的应用探讨

A DISCUSSION ON APPLICATION OF THE MULTIPLE RECOGNITION AND REMOVAL TECHNOLOGY IN PROCESSING OF MARINE SEISMIC DATA

海洋拥有丰富的油气资源,地震勘探则是准确定位海洋油气资源的重要手段。本文就多次波识别与去除技术在海洋地震资料处理中的应用展开分析。首先从海洋地震资料多次波识别的角度,分别介绍深水区与浅水区的多次波特征,然后从海洋地震资料处理的角度,详细阐述深水区与浅水区地震资料多次波的去除方法,以期为区域和局部地质构造、层序地层、油气地质特征等方面研究提供高分辨率、高保真度和高信噪比的地震剖面和成果数据,为降低海洋油气勘探风险与难度提供一定借鉴。

Seismic exploration is an important means to accurately locate the abundant offshore oil and gas resources.This paper analyzes the application of multiple wave recognition and removal technology in marine seismic data processing,firstly,from the perspective of recognition of multiple waves of marine seismic data,introduces the features of multiples of deep and shallow water zones respectively,then,from the point of marine seismic data processing,describes in detail the method of removing multiples from seismic data on deep and shallow water zones,thus provides high resolution,high fidelity and high signal-to-noise ratio seismic profile and result data for the study of regional and local geological structure,sequence stratigraphy,hydrocarbon geological characteristics,etc,and some reference for reducing the risk and difficulty of offshore oil and gas exploration.
