We numerically simulate filtration noise within the framework of the earlier proposed model for the generation of acoustic noise as a result of excitation of relaxation self-oscillations. The simulation is performed for typical parameters of reservoir rocks. As a result, appearance of the radiation frequencies observed in the experiment is demonstrated. It is also shown that due to the nonlinear interaction between elementary sources of the acoustic radiation, its spectrum is enriched with combination frequencies. In the case where the ratios of the frequencies of the interacting oscillators are fractional, the acoustic interaction can lead to nonlinear synchronization of elementary radiation sources.

过滤噪声的数值模拟

我们在早先提出的模型框架内对过滤噪声进行数值模拟,以产生由于弛豫自振荡的激发而产生的声学噪声。对储层岩石的典型参数进行模拟。结果,证明了在实验中观察到的辐射频率的出现。还表明,由于声辐射的基本源之间的非线性相互作用,其频谱丰富了组合频率。在相互作用的振荡器的频率比是分数的情况下,声学相互作用会导致基本辐射源的非线性同步。
