串感现象的综合分析及应对方法探讨

随着石油勘探的不断深入,勘探规模越来越大,精度要求越来越高,电磁干扰对地震资料的影响越来越受到重视,勘探工区也越来越复杂,随之而来的问题也越来越多,其中串感对地震资料的影响不容忽视.本文简述了如何用屏蔽、隔断、接地、小前放增益、剔除等方法减弱串感对地震资料的影响.

Integrative analysis of crosstalk phenomenon and discussion of countermeasures

Along with the constantly deepening of petroleum exploration,the exploration scale becomes larger and larger,which is demanded higher and higher precision.The influence of electromagnetic interference on seismic data has been paid more and more attention,the exploration work zones become more and more complex and the problems associated with complex work zones are more and more,among which the influence of crosstalk on seismic data cannot be neglected.The paper briefly expounded how to use the shield,isolation,earth,small pre-amp gain and rejection to attenuate the influence of crosstalk on seismic data.
