【摘要】 渤中21-2构造潜山目的层为下古生界碳酸盐岩地层,埋藏较深,储集空间以裂缝、孔洞为主,非均质性较强,受控因素多,地震响应关系复杂。这一地区地震资料品质较差,并且该构造没有钻井,储层的平面展布特征难以把握。在储层地质与地震响应特征分析的基础上,应用相干分析、属性分析、曲率分析和频率分解等技术,从不同角度对该潜山有利储集层发育区进行了预测。这些技术都存在一定的局限性和多解性,而综合利用多种地震预测技术进行综合分析,可以提高预测结果的可靠性。更多还原

【Abstract】 The target layer of BZ21-2 buried-hill is deeply bur-ied in carbonate rock reservoir of lower Paleozoic. Fractures and holes are main reservoir space types and has the charac-teristics of strong non-homogeneity,controlled by many factors and complicated seismic response. With poor seismic data quality and without any drilling data,the plane distribu-tion characteristics of the reservoir are difficult to predict. Based on the analysis of reservoir characteristics and seismic response,by using the technology of coherent analysis,at-tributive analysis,curvature analysis and frequency resolu-tion ,the favorable developed area of reservoirs has been pre-dicted from various aspects. However,these techniques have some limitation and ambiguity,and only an integrated pre-diction by using them can improve reliability of the predic-tion.更多还原
