针对低信噪比转换波资料处理中常规自动静校正产生假静校正量和速度分析失效的两个难题，我们将处理流程分成两条数据流。其中一条专用于作静校正及速度分析，无需刻意追求分辨率与保真度，只要求有起码的信噪比；另一条则是利用前一条数据流所求得的静校正值和速度对转换波资料作精细处理。实际资料的处理表明，该方法可以收到满意的效果。 In order to solve the two problems of pseudo-static correction and failure of velocity analysis in the conventional automatic static correction in low signal-to-noise ratio converted wave data processing, we divide the processing flow into two data streams. One dedicated to static correction and speed analysis, without deliberately seeking the resolution and fidelity, only requires a minimum of signal to noise ratio; the other is the use of the previous data obtained by a static correction and speed of the conversion Wave data for fine processing. The actual data processing shows that the method can receive satisfactory results.
