苏北盆地的SXF地区是典型的低信噪比地震资料地区,断裂系统复杂,构造破碎,圈闭面积小,火成岩发育。经过处理、解释一体化工作,进行有针对性处理,提高了资料的信噪比;运用地质规律指导处理解释,充分应用新技术,落实了该区的断裂组合和火成岩分布,对区内油藏分布规律有了新的认识。

Because of complex fracture system, faulted structures, and rich igneous rocks, SXF area is a representative low signal-to-noise ratio seismic data region in Subei basin. With collaboration of interpretation and data processing personnel combined with object-oriented processing measures, the signal-to-noise ratio of the data was greatly improved. The fracture pattern and igneous rock distribution, which was determined with new technologies under the guide of geological rules, leads to new sights about the distribution of oil reservoirs in the region. Thus great breakthrough in exploration has been made.
