油井干扰特征分析及其野外压制方法

【摘要】 东营凹陷开发程度较高,油井密布,工业设施多,影响了地震资料的信噪比和分辨率。本文调查了油井干扰产生机制及传播途径,分析了表层对油井噪声的衰减程度,对比了不同方法对油井噪声的压制效果。得出了避开油井干扰与压制油井干扰相结合的降噪方法。更多还原

【Abstract】 Because of the great development of Dongying depression,many oil wells were drilled densely,and there are many industrial machines.Consequently it attenuates the signal to noise ratio and resolution of seismic data.This paper gave out the generated ways and the transmitted paths of the oil well noises in Dongying depression.It also analyzed the degree of the ambient noise attenuated by subsurface.We have compared one method to attenuate ambient noises with another method.As a result this paper put forward to the method to attenuate ambient noises by keeping away from ambient noise and minimizing ambient noise.更多还原
