|
摘要
为了解决现行工业化软件中工业电干扰压制处理的计算效率和处理精度较低的问题,提出并推导了一种压制多种频率成分工业电干扰的新算法。该算法采用余弦函数组合近似逼近工业电干扰,根据最小二乘法最优逼近和归一化互相关系数实现多种频率成分工业电干扰的自动识别与自适应压制。在理论合成数据和松辽盆地CD地区的地震资料工业电干扰压制中进行应用,其结果表明,新算法的保幅性较好,信噪比较高,在勘探成熟区的高保真叠前地震资料预处理方面具有较好的推广应用价值。
In order to solve the problems of the low calculating efficiency and low processing precision of the current industrial interference suppression process in industrial software, this paper presented and derived a new scheme to suppress multi-frequency component industrial interferences simultaneously. The algorithm uses a combination of cosine functions to approximate the industrial interference, and achieves automatic identification and adaptive suppression of multi-frequency component industrial interference according to the optimal approximation of least square method and the normalized cross-correlation coefficient. It was applied to theoretical synthetic model and practical seismic data in CD area of Songliao Basin. the result shows that the proposed scheme is with perfect amplitudepreserved and high signal to noise ratio, therefore, the new algorithm can be an important technical guidance for high precision amplitude preserved seismic data preprocessing in mature exploration area.
