本文将扩展AVO分析技术用于渤海油田油气刻画,给出了详细的应用流程.文中将扩展AVO分析技术与常规AVO分析技术的应用效果进行了对比.渤海油田的应用结果表明:应用扩展AVO分析技术检测气层分布,和传统AVO属性分析技术相比,气层异常明显,连续性强且边界清晰,背景干净,多解性大幅度降低. In this paper, the extended AVO analysis technology is applied to the oil and gas depiction in Bohai Oilfield, and a detailed application flow is given.This paper compares the application effect of the extended AVO analysis technology with the conventional AVO analysis technology.The application results of Bohai Oilfield show that the application of extended AVO analysis Compared with the traditional AVO attribute analysis techniques, the gas layer is obviously abnormally distributed, the continuity is strong, the boundary is clear, the background is clean, and the multiplicity of solutions is greatly reduced.
