摘　　要：在工业化采油区中，油井和工业电网产生的50Hz工业电干扰对地震资料成像有较大影响。在综合研究50Hz工业电干扰压制技术的基础上，利用工业电的特性探索了一套高精度自适应压制技术。实际地震资料处理效果表明，采用该方法压制50Hz工业电干扰的效果较好，既保持了地震波的动力学和运动学特征，也提高了地震资料的信噪比，保真度高且节约处理成本。In the industrialized oil production blocks, the interfering waves of 50Hz industrial electricity generated from the oil producers and industrial electricity network will seriously influence the imaging of seismic data. On the basis of the combined study of the depressing technique of the above interference, by means of the characteristics of the industrial electricity, a set of high-precision adaptive depressing technique is explored and developed. The pro- cessed effects of the actual seismic data show that the depressing effects of the method are much better ： can not only maintain the dynamic and kinematic characteristics of the seismic waves, but also enhance the signal-to-noise ratio of the seismic data, and furthermore the high-fidelity can save the process cost.
