分析、利用近场子波特征,完成对海上单个空气枪进行测试从而实现对空气枪状态的质量监控,在海洋地震勘探过程中是一种简便、实用的方法。本文介绍了国外最具代表性的气枪子波理论模型,分析了经典子波模型的理论公式。针对海上单个空气枪质量监控等问题进行了理论分析,给出了利用近场子波实现对单枪测试的操作步骤。实例表明,该方法简便、有效、可行。
Analysis, the use of near-field wavelet features, the completion of a single sea air gun test in order to achieve the status of the air gun to monitor the quality of the marine seismic exploration process is a simple and practical method. This paper introduces the most representative model of air gun wavelet in foreign countries and analyzes the theoretical formula of classical wavelet model. Aiming at the quality control of a single air gun at sea, the theoretical analysis is given, and the operation steps of single-gun test using near-field wavelet are given. The example shows that this method is simple, effective and feasible.
