在检波点域分离50Hz工业干扰

地面高压线路和设备的增加为油区工业化带来了方便,但其产生的50Hz工业干扰却严重影响了这些地区的野外地震数据采集质量。本文以官7地区三维地震资料为例,研究开发出了一种有效压制50Hz工业干扰的方法——检波点域分离法。实际资料处理证明了该方法的有效性。

Separating 50Hz industry disturbance in geophone domain

The upgrades of power lines and equipment provided convenience for oil area industrialization, but the 50Hz industry disturbance resulted from the lines greatly affects the quality on field data acquisition . A method for suppressing effectively 50Hz industry disturbance-separation in geophonedomain is developed in a case studying of Guan7 area 3D seismic data . The real seismic data processing proves that the method is effective for suppressing 50Hz industry disturbance.
