| 摘 要： | 依托于地震工程数据库平台,在现有静校正方法的基础上,提出一种新的静校正技术———先验信息约束静校正技术.该技术充分利用各种已成熟或接近成熟的技术,综合各种地质和地球物理数据,通过点、线、面一体化的表层交互分析解释方式,调整建立符合当地区域地质特征的表层结构模型,利用模型法静校正公式算出每个接收点和炮点的静校正量,最终静校正量由模型静校正量约束折射或层析校正量所得.这样就实现了正确构造背景下高精度成像,同时也为解决表层静校正问题提供可选择的静校正技术手段.实际应用表明,该方法和技术对DCZ地区大量的地震数据是适用的和有效的,在该区的地震勘探中解决了一定的问题并取得了一定的效果. |
