而时移时差在确定地下油水分布时是一个很重要的参数，因为时移时差包含了储层速度的变化信息。
Time lapse time difference is an important parameter in the determination of distribution for underground oil and water, because it includes the variation information of reservoir velocity.
讨论了利用测井声波时差和地震层速度预测地层压力的方法及其应用。
Logging sonic differential time and seismic interval velocity are used to estimate formation pressure in this paper.
这说明密度与各储层参数之间具有较好的线性关系，而声波时差或速度与储层参数之间的相互关系要复杂得多。
It shows that density has a better linear relation with different reservoir parameters, but the relation of sonic interval transit time or velocity with reservoir parameters is very complicated.
该方法克服了单纯地震层速度或单纯声波时差预测地层压力的局限性。
This method removes some limitations in formation pressure prediction using only seismic interval velocity or acoustic interval transit times.
而脉冲配对产生的大量模糊时差，不仅降低了处理速度，还会干扰对其它信号的时差提取和信号分选处理。
The large Numbers of ambiguous TDOAs produced by pulse pairing, not only reduce the speed of processing, but also interfere the extraction of TDOA produced by other signals and pulse deinterleaving.
为此，采用T-X域时差变换滤波技术，即在T-X域内将曲线型相干噪声线性化，通过视速度差异去除噪声，从而达到压噪目的。
Therefore, moveout transform filtering method in T-X domain was adopted, which linearized the curved coherent noise in T-X domain, and remove noise by the contrast of apparent velocity.
