The successful application of DWD in the short-radius deep sidetracking of horizontal wells in Taha region provides an effective way for reducing the cost of short radius horizontal well drilling, improving the operation efficiency, eliminating the operational risks, it is worthy to be introduced in oilfields.

This paper applied three joint time frequency analysis ( JTFA) methods to a surface discharge signal in oil, i.e., Short time Fourier transformation ( STFT) based spectrogram, Wigner distribution ( DWD) and Gabor spectrogram ( DGS).

将短时傅立叶变换谱、Wigner分布及Gabor谱等3种联合时频分析方法应用于离散时间域，分析并处理了油中沿面放电波形。
