关于地震叠前时间偏移技术与应用问题的思考

Consideration of seismic prestack time migration technique and application

随着叠前时间偏移方法的趋于成熟和与之配套技术(如静校正和去噪等)的不断完善以及计算机性能的提高,特别是微机机群的迅猛发展,目前叠前时间偏移技术在油气藏勘探开发中的作用已被广泛认同。本文在简要归纳方法原理的基础上,通过与其他同类技术的对比分析,阐述了地震叠前时间偏移技术所拥有的独到优势,指出现阶段大力开发并推广应用该项技术的重要性和可行性以及该项技术可能的应用领域,同时浅析了叠前时间偏移技术的适应性,提出了实际应用中应特别注意的问题以及对今后该项技术发展的思考。

Effects of the prestack time migration technique on hydrocarbon exploration and development have been widelyapproved at present along with a prestack time migration technique is going to mature, its related techniques (staticcorrection and noise removal etc) is being very well equipped and performance of the computer is improved, particu-larly the rapid development of the computer cluster. Based on concluded method and principle of the this techniquespecific advantage of it was expounded, and pointed out importance and feasibility to spread and apply this techniqueand fields where it can be used at present, meanwhile, simply analyzed its adaptability and put forward actual problemsin the practice and consideration of this technique for development in the future, and making a comparison between itand others.
