三维地震勘探精细处理技术在智能矿井生产中的应用

Application of 3D Seismic Prospecting Data Fine Processing in Intelligentized Mine Production

智能矿山建设迫切需要矿井地层“透明化”,应用高精度物探技术可以为其提供可靠的地质数据,能够有效避免矿区各种地质灾难。基于此,国内外广泛开展了智能化矿山物探保障技术研究,其中包括三维地震野外采集、数据处理、资料解释等高精度地震勘探技术的研究取得较大进展。通过列举三维地震勘探精细处理技术如非网格层析静校正、优化串联反褶积前、叠前时间偏移等在资料处理中的效果,指出在资料处理过程中参数测试的重要性。某勘探区应用实例表明,选取精细处理最佳参数,可以明显提高处理成果的信噪比,获得的地震剖面能够清晰反映目的层起伏形态、构造状态等地质信息,其资料解释结果与矿井实际揭露相符,验证了精细处理技术在矿区深部的应用效果。

The intelligentized mine construction is urgently needed mine strata to reveal more.To use precision geophysical prospecting technology can provide reliable geological data,effectively avoid mine area various geological hazards.On this ground,intelligentized mine geophysical prospecting support technologic studies have been widely launched,in which,including 3D seismic field data acquisition,data processing,data interpretation etc precision seismic prospecting technological studies acquired greater progress.Through the list of 3D seismic prospecting fine processing techniques such as non-grid tomographic statics,before series deconvolution optimization,prestack time migration etc effects in data processing have pointed out the essentiality of parametric test in data processing process.A case study of the application in a prospecting area has shown that to select optimum parameters in fine processing can promote signal-to-noise ratio of processed results obviously.Processed seismic section can reflect target undulation,structural form etc geological information clearly.The data interpretation results are in accordance with mine actual revealed facts,thus verified fine processing technology application effect in mine area deep part.
