无自由套管井固井质量评价方法研究

Non-free Casing Well Cementing Quality Evaluation Method Research

无自由套管井测井无法刻度,现需要更精确的一种处理方法进行评价,由此出现的双波形法。套管波和地层波有不同的频率范围,利用其特性可以区分套管波和地层波,而且可以评价快速地层的固井质量。文中主要介绍了双波形法的原理,以及它评价无自由套管井的特点和其处理软件。

Non-free casing logging cannot be calibrated.A more accurate process method is needed.Therefore double-wave shape is formed.Casing wave and formation wave have characteristics of different frequency range which can be used to identify casing wave and formation wave.Fast formation can be evaluated as well.The paper presents the principle of dual wave method,features and the processing software.
