地震资料信噪比低一直是制约着长岭断陷地区油气勘探发展的主要问题。本文通过对近十几年来长岭断陷南部采集方法的整理与对比，总结出一系列该地区提高资料信噪比的方法。同时，对火山岩下覆地层反射能量弱的问题，提出了改进思路，供以后采集处理人员参考。

Low signal-to-noise ratio(S/N) of seismic data is the restriction to oil and gas exploration of Changling fault depression. In this essay, through the collection and comparison of Changling fault depression in last decade, a series of methods to improve data S/N has been summarized. Meanwhile, focus on weak relfection energy problem which is under volcanic strata, improvement ideas has been proposed which as a reference for later collections and processing.
