【摘要】 野外地震检波器组合是提高原始资料信噪比常用而重要的方法,但在压制干扰波的同时也损害了有效波。单点数字检波器小道距、高覆盖、不组合的野外采集方式逐渐得到应用,势必带来数据量的增大、信噪比的降低,因此需在室内进行地震道组合处理。本文在理论分析的基础之上,结合胜利油田YX工区单点数字检波器接收、5m道距的资料进行了室内组合分析,探讨了室内地震道组合方法、流程以及应注意的问题,展示了室内道组合的效果。更多还原

【Abstract】 The field seismic geophone array is common-used and important method for improvement of S/N ratio of raw data, but damages significant events while suppresses interference waves. The field acquisition pattern of single-point digital geophone characterized by short group interval, high folds and array-free is gradually applied, but may bring increasing of data volume and lowering of S/N ratio, so the indoor seismic overlapping processing is necessary. On the basis of theoretical analysis and in combination with the data of single-point digital geophone receiving and 5m group interval in YX work zone of Shengli Oilfield, the paper carried out indoor overlapping analysis, probed indoor seismic overlapping method, flow and the issues that should need pay attention for and showed indoor overlapping effects.更多还原
