在石油勘探的早期，都是通过最基础的地震波传播时间与震源到检波点距离的关系入手研究其运动学特征的。通过时距曲线，我们可以分析地震波的传播规律，了解地下构造，虽然现在更多的是挖掘动力学特征，但是运动学特征作为最原始基础的分析也是必不可少的-Early in the oil exploration, are through the most basic of seismic wave propagation time relations with the distance between source and receiver starts its kinematics. Through the duration curve, we can analyze the propagation of seismic waves, underground structures, although mining is more dynamic features, but kinematic characteristics as the basis for most original analysis is essential
