三维地震识别及其应用

三维地震识别就是一个以三维迭后地震资料为对象的多储层、多目标、多(矢量)特征参数的灰色油气识别。首先对目的层地震数字序列提取灰色、模糊、分维、振幅、自相关5类19个地震特征参数向量,然后在地质建模的基础上,进行灰色模式训练与识别,获得整个评价区的油气检测结果。其输出结果,是以形象、直观、醒目的彩色图形形式显示输出的各储层、每个目标的空间识别分类结果及各测线识别结果的精细描述图,便于结果的地质解释和评价。该方法在辽河某油田油(气)勘探潜力评价研究中取得了好的效果

RECOGNITION OF 3 D SEISM AND ITS APPLICATION

The recognition of 3 D seism introduced in this paper is a grey oil gas recognition with multi reservoirs , multi objects, multi characteristic(vector) parameters based on 3 D seismic data. Firstly, 19 seismic characteristic parameter vectors are extracted in about five species such as grey, fuzzy, fractal, amplitude , self correlation and power spectra from data sequence of the target stratum. Then, training and recognition of a grey pattern are made and the oil gas inspection results of all over the evaluation area got based on the geologic modeling. The output of this method describes the spatial recognition and sorting results of reservoirs and targets with intuitionistic colorful graphs and displays exact graphs of recognition results of seismic profiles so that geologic explanation and evaluation can be done. The method has been applied to the evaluation and research of the exploration potential of an oil gas field in Liaohe and has gained a good result.
