摘要
气枪震源是一种海洋探测的无污染新型装备,用以产生冲击子波,气枪震源技术的关键是如何控制子波的特性,使之适合石油勘探作业。研究一种气枪震源的激发原理及基本参数,探讨气枪震源的两种组合形式的特点,同时分析影响气枪震源组合特性的基本参数及子波特性产生机理,获得影响水下气枪组合震源子波特性的六个主要的基本参数,并对单气枪在不同气压和不同沉放深度下做了仿真计算,为优化组合震源提供理论依据。
The air-gun hypocenters,as a type of non-pollution equipment,emit shocking waves for ocean exploration.One of key for designing an air-gun hypocenter is how to optimize the characters of shock wave.A novel air-gun hypocenter is studied,in which the basic parameters of air-gun hypocenter and two different combinations are discussed.Based on analyzing the mechanism of underwater subsidiary wave of air-gun hypocenter,six dominant design parameters are found out,they greatly determine the feature of subsidiary wave.The characters of single air-gun at different air pressure and submergence depths are investigated by simulation,from which some theoretical supporting for optimal combination of air-gun hypocenter can be obtained.
