【摘要】 由于地表及地下因素复杂,再加上表层静校正、波场复杂及有效信号提取难、速度场复杂以致成像精度低等各方面因素,给地震资料处理工作带来了很大的难度。针对低信噪比资料的特点,引进GEOSCOPE系统为平台,利用GEOSCOPE解释软件灵活方便的特点,并在实际资料解释处理应用中取得了一定的效果。本文对比低信噪比资料解释过程中的Alpha滤波处理前后的效果作了简要介绍,以推进复杂地表条件下低信噪比地震资料解释水平的共同提高。更多还原

【Abstract】 Because of complexity of the earth’s surface and subterranean,as well as surface layer static corrections,wave field’s complexity,hard for picking-up efficiency signal and low precision of imaging by velocity field’s complexity,and so on,it is very difficulty to process the seismic data.Aiming at the characteristic of low s/n ratio data,we introduced into GEOSCOPE System,using the characteristic of agility and convenient of the GEOSCOPE System.And we have procured some effect in processing practical data.This paper contrasted the effect of fore-and-aft Alpha filter wave reprocessing.So advance the level of low s/n ratio seismic data explain by complexity of the earth’s surface.更多还原
