细分面元在高密度三维地震勘探中的应用

东濮凹陷目的层埋藏深、断块破碎，复杂构造的精确成像是摆在物探工作者面前的难题。经过吸取国内外高密度地震勘探的先进技术和经验，以解决地质问题为目标，研究确定了细分面元观测系统，解决了复杂断块的精细成像问题，以较低的成本提高了地震资料的品质，并在应用中取得了明显的效果。

Application of Flexi-bin in high density 3-D seismic exploration

The major exploration difficulties in Dongpu depression are deep buried targets and small broken faults.Accurate imaging of complicated structures poses a great challenge to geophysicists.Focused on solving geological problems,by studying and assimilating advanced high density seismic exploration techniques and experiences,we investigated and formed a typical Flexi bin seismic geometry to precisely imaging complicated faults.The method improves seismic data quality at relatively lower cost and achieves satisfactory results in the applications.
