伊犁地区多次波问题一直是限制该区石油地质研究及获得深层地震反射资料的主要干扰，有效地压制多次波是该区油气勘探获得突破的关键，本文通过对伊犁地区多次波特征的分析，选取合理的识别方法分辨一次波和多次波，在衰减多次波过程中，综合使用了反褶积、F-K滤波、τ－P变换和时变下切除等手段，在补偿深层能量处理中，采用多次自动剩余静校正迭代和随机噪音衰减等方法。利用这些方法所处理的地震剖面多次波得到有效衰减，一次波反射能量加强，真实可信，并且有一定的连续可追踪性。
The problem of multiplicity in Ili region has been the main disturbance that limits the petroleum geology research and obtain the deep seismic reflection data in this area. Suppressing multiple waves effectively is the key to the breakthrough of oil and gas exploration in this area. Based on the characteristics of multiple waves in Ili region In the process of decaying multiples, deconvolution, FK filtering, τ-P transform and time-varying lower excision are all used in the compensation of deep energy processing In the method, several methods such as automatic residual static correction iteration and random noise attenuation are adopted. The seismic waves processed by these methods can effectively attenuate the multiples of the seismic profile, and the reflected energy of the primary wave is strengthened, so it is credible and has certain continuous traceability.
