在近几年,海相四分量(4C)采集和处理技术的发展使得该项技术在大多数地区和不同水深中的应用成为可能。然而,与常规等浮电缆测量相比,其成本较高,因此它的成功将取决于应用适当,还必须证实其结果可以解释,并能以技术成本有效的方式加以应用。 本文并不强调处理和解释方面的技术细节,仅讨论了三个实例的结果,每个都显示了海相4C数据的不同应用。应用涉及到成像和表征,包括改善低阻抗P波储层的成像,如何从多分量属性中推断出砂岩/泥岩含量及对流体识别。三个实例研究显示,在海相4C数据分析中具有哪些优势能进行清晰的储层成像、辨别流体和岩石特性。
In recent years, the development of marine four-component (4C) acquisition and processing technologies has made possible the application of this technology in most areas and at different depths. However, its cost is higher than with conventional streamers, so its success will depend on the proper application and its results must be demonstrated and can be applied in a technically cost-effective way. This article does not emphasize the technical details of processing and interpretation, but discusses the results of only three examples, each showing a different application of marine 4C data. Applications involve imaging and characterization, including improving the imaging of low-resistivity P-wave reservoirs, how to infer sandstone / mudstone content and identification of fluids from multi-component attributes. Three case studies show the advantages of marine 4C data analysis for clear reservoir imaging and fluid and rock characterization.
