叠前深度偏移技术摆脱了常规叠后时间域处理要求时距曲线是双曲线的简单假设，可以适用于各种复杂构造。本文阐述了叠前深度偏移的基本原理、处理流程以及在煤田二维、三维地震资料处理中初步的应用效果。文章最后指出：为了提高煤田复杂地区地震勘探的效果和解释精度，开展叠前深度偏移势在必行。
The prestack depth migration technology is free from the simple assumption that the time-distance curve is a hyperbola when the conventional post-stack time-domain processing requirement is met and can be applied to various complicated structures. This paper describes the basic principle of prestack depth migration, the processing flow and the preliminary application results in the two-dimensional and three-dimensional seismic data processing of coal fields. Finally, the article points out that it is imperative to carry out prestack depth migration in order to improve the seismic exploration results and interpretation accuracy in complex areas of coalfields.
