二连盆地强干扰区地震采集方法探讨

二连盆地地震反射资料频率及信噪比低的原因是，区内地表为第四系泥沙覆盖，岩石松散，目的层埋深浅，小断层发育以及环境噪声等，这些因素极大地影响了采集资料的质量。针对二连盆地的上述地质特征及环境因素，进行了多种不同检波器组合方式的试验，并对获得的资料作了对比分析，采用了在胶泥层激发和平行线性组合检波方式接收的方法，使资料的品质得到了明显的改善。

Seismic data acquisition in areas with strong interferences in Erlian basin

Seismic reflection data acquired in Erlian basin was generally low in frequency and signal-to-noise ratio. Factors affected the data quality include the Quaternary washings covering the earth surface, unconsolidated rocks, shallow depth of targets, enriched minor faults, and ambient noises. Data acquired with different exciting formations and geophone arrays show that the best data quality can be achieved by shooting in cemented mud layer and with parallel linearity array.
