摘要
本技术是通过8类方法,对地震、测井、地质等多种资料进行分析、处理,从中提取地震有效多属性信息。通过多种地质—物理模型,借助于多维分析综合确定地质预测目标,对碳酸盐岩含气储集体特征实现预测评价。实际生产应用表明,应用地震多属性技术将会有效地减少对预测目标的多解性,显著地减少偏差。可为提高油气勘探成功率及油气储量计算提供准确的地质依据,是一项实用的成熟技术。
This technique can obtain effective seismic multi-attribute information by applying 8 kinds of methods to analyze and process seismic, logging and geological data. Based on many kinds of geological-geophysical model, with the help of multidimensional analysis to define geological prediction objection, it can realize prediction evaluation of the carbonate gas-beating reservoirs. Production application indicated that applying seismic multi-attribute technique could effetely reduce the ambiguous solutions of prediction object, thus reduce errors obviously. This practical ripe technique can provide with accurate geologic basis for improving oil and gas exploration success ratio and calculation of hydrocarbon reserves.
