Abstract:"String induction" is interference that often meets in a process of seismic data acquisition,which affects the quality of seismic records when it is serious.Based on recent studied results and experimental data,the paper systematically analyzed and expounded the natural characters,produced conditions,forming principle and followed rule from aspects of analyzing source attributes,producing principle,relation with acquisition equipment and prevention measure,and summarized a set of technical methods preventing and removing "string induction" effectively on that bases and in combination with practical results in the field.The practical application showed that different prevention measures should be selected according to different prevented objects; the integrative usage of each measure can achieve better effects.It is especially worth to notice that the effect removing "string induction" is better if changing the intrinsic feature of factors forming "string induction".
