摘要:
WVD时频分析是一种高精度的时频分析方法,在碳酸盐岩烃类检测中具有更高的精度。但是交叉项的存在,会对有效信号造成严重干扰,导致其精度有所下降。为此,利用两种加权窗函数分别抑制交叉项在时间方向和频率方向的影响,理论计算显示了其有效性。在塔里木盆地哈拉哈唐地区地震资料的实际应用中,利用该方法获得了高精度的时频分析结果,为该区今后的勘探开发部署提供了重要依据。
Abstract:
WVD is one of the higher-precision technology of time-frequency analysis at present,especially in the hydrocarbon detection of carbonate rock.However,the precision of WVD reduces a little because of the existence of a cross term in it.Using two weighting window functions,we can suppress the influence of cross term both in time direction and frequency direction.The theoretical result calculated with WVD is better.This method was utilized in the district of Halahatang in Tarim Basin,and we got a high-precision result of time-frequency analysis.It has provided an important foundation for later exploration and development deployment in this area.
