摘要
简要介绍了叠前深度偏移 (PSDM)的方法技术 ,主要包括叠前深度偏移成像 ,旅行时计算和速度模型建立3个部分。将叠前深度偏移技术应用于 3个有代表性的复杂构造地区 ,其结果在断层显示的清晰度、断块识别的准确度以及高速盐体的边界成像精度等方面均有明显的提高。
Prestack depth migration (PSDM) is briefly described, which consists of prestack depth migration imaging, traveltime calculation and construction of velocity model. The PSDM was applied to three complex structure regions, which resulted in a clearer and more accurate image for faults and higher imaging precision for high velocity salt boundary. The PSDM results allowed for high precise geologic and structural interpretation in complex regions.
