Seislog又称合成声波测井。在碳酸盐岩地区 ,Seislog资料对缝洞系统的预测非常有效 ,只要缝洞体中含有流体 ,它的速度必然比围岩的速度低 ,在Seislog剖面上反映为孤立、不连续的低速异常体。本文从Seis log资料处理的方法原理、处理步骤和实际应用几个方面进行了阐述。 Seislog, also known as synthetic sonic logging. In the carbonate area, the Seislog data is very effective in predicting fracture-cave systems. As long as the fracture-cavity contains fluids, it will inevitably have a lower velocity than the surrounding rock and an isolated and discontinuous low-velocity anomaly on the Seislog profile body. This article elaborates the method principle, processing steps and practical application of Seis log data processing.
