本文在假设地层吸收衰减量与非线性扫描补偿量相等的前提下,从理论上推导出可控震源扫描模型的函数关系,并采用优选法与抛物线插值法,经过四次试验,求出最佳离散扫描参数.文中还以实例讨论了设计步骤;对扫描瞬时输出能量作了图形剖析.此法只要求设计者了解工区地质情况和干扰波特征,所有计算工作均可在小型计算器上完成.本方法具有设计步骤简单,周期短,参数优化的特点.
Based on the assumption that the attenuation of formation absorption is equal to that of non-linear scanning compensation, this paper theoretically deduces the functional relationship of the fouling scanning model and uses the optimal method and the parabola interpolation method to obtain the best discrete Scan parameters.The article also discusses the design steps by examples and graphically analyzes the instantaneous output energy of the scan.The method only requires the designer to understand the geological condition and the characteristics of the disturbing wave in the work area and all calculation work can be done on a small calculator The method has the characteristics of simple design steps, short period and parameter optimization.
