摘要
经过多年的探索和研究 ,地震资料的反演方法已经逐渐成熟 ,反演成功的实例报道也不少见〔1〕。为取得较好的反演效果 ,本文从实际资料出发、从应用的角度对约束稀疏脉冲反演的基本原理 ,及适用的范围进行了探讨 ,并应用该方法对大庆油田某一二维地震资料进行了波阻抗反演。在反演结果剖面上清晰的识别出某一地层上倾尖灭点 ,并在整个工区范围内拾取了该上倾尖灭地层 ,为寻找地层性隐蔽油气藏指明了方向。
With many years' research and hard works by geo-scientists, seismic data inversion methods have been greatly improved. Many successful inversion instances have been reported. But in order to get a good inversion result, there are lots of things to be done and to be known for an inversion applier. In this research, the exploration data was studied carefully, and the Constrained Sparse Spike Inversion was applied to the 2D seismic data of the studied area. On the inversed seismic profiles, one obscure updip wedge-out formation within the objective interval was picked up. Practice shows it is very important to choose the suitable inversion method and use all the prior geo-information for one to get a satisfying inversion result.
