随着油气勘探开发的不断发展,利用地震属性进行储层预测的方法得到了广泛的应用,并且在生产中取得了较好的效果.本文采用的谱分解和地震多属性联合的方法进行储层厚度预测,克服了单一属性分析存在的多解性和多属性分析在断层处预测不准确的问题,以及仅利用谱分解方法时,由于其预测基础的限制,部分复杂地区对砂体厚度的预测效果存在一定误差这一问题,可以较为准确地预测出目的层的储层厚度,同时,在传统地震分析中非常难发现的地质信息,谱分解之后比较容易发现,有助于进一步解释.实际地震资料结合井信息和分层数据的标定,对储层厚度的预测进行了较为详细的研究.研究结果表明,此方法在原理和实际应用上都是可行的,提出了一种储层厚度预测的新方法.
With the continuous development of oil and gas exploration and development, the method of using seismic attributes for reservoir prediction has been widely used and has achieved good results in production.In this paper, the combination of spectral decomposition and seismic multi-attribute method is used to reservoir Thickness prediction overcomes the problem of inaccurate prediction of multi-solution and multi-attribute analysis in single attribute analysis, and the prediction of sand body thickness in some complex areas due to the limitation of prediction based on the spectral decomposition method The effect of the existence of a certain error of the problem, you can accurately predict the reservoir thickness of the target layer, at the same time, in the traditional seismic analysis of geological information is very difficult to find, after the spectral decomposition easier to find, help further interpretation of the actual earthquake The data is combined with the well information and the calibration of stratified data to make a more detailed study on the prediction of reservoir thickness.The results show that this method is feasible both in principle and practical application and a reservoir thickness prediction new method.
