摘要

三维可视化技术应用透视显示技术,把代表某地质异常体的振幅信息在三维空间突出出来,采用种子点技术进行空间自动追踪,在横向储层预测方面表现出快捷准确的优点。离散子波标定技术通过对声速曲线的改造,去除次要岩性变化干扰,突出了有效的储层信息,通过将不同反射界面的地震响应分开显示,精确确定储层在地震剖面上的响应位置及振幅特点。两种技术相结合,可以有效提高储层预测的准确性和工作效率,在港西地区明化镇油层预测中取得较好的效果。
Using perspective display technology for true three-dimensional visualization,the amplitude information representing geological abnormal bodies was stand out in three-dimensional space.These spaces were automatically tracked by the seed point technology.Advantage of faster and more accurate of the technology was showed in horizontal reservoir prediction.Exploded synthetic is an analytical tool to evaluate the synthetic trace response generated from individual geological boundaries.Individual synthetic trace components are displayed by this method for each layer.It is then possible to evaluate how reflections from individual geological interfaces interfere with one another to create the total synthetic trace response.Combining these two technology,accuracy and efficiency in reservoir prediction can be improved remarkably.Good results were gained in Gangxi Oilfield reservoir prediction.
