摘要
静校正是油气以及煤田地震勘探中处理环节最为重要的一环。其目的是解决近地表起伏以及地表低、降速带横向变化剧烈对地震资料的影响,在处理复杂山地地震资料时尤为关键。目前,折射波静校正和层析静校正是煤田地质勘探中常用的两种静校正技术。本文以山西复杂山地资料为基础,综合分析两种静校正技术优缺点以及适用性。
Statics correction is the most important part of oil gas and coal field seismic exploration, solving the problem on seismic data caused by near surface relief, low surface, and the violent horizontal variation of the falling speed belt is the purpose,and it's significant to handle seismic data of complicated mountain area. Refraction static correction and tomostatics are regular statics correction in coal exploration. Based on the data of complicated mountain area in Shanxi Province,applicability and merits and faults of this two kinds of statics correction technology were analyzed in this paper.
