提高补偿密度测井纵向分辨率的处理技术

Vertical Resolution Enhancement Technique for Compensated Density Log.

范宜仁等·提高补偿密度测井纵向分辨率的处理技术，测井技术，１９９５，１９（２）：１５１～１５６补偿密度测井是评价地层孔隙度和岩性的重要测井资料，提高补偿密度测井纵向分辨率是评价薄储层的重要前提。详细介绍了用近源距计数率计算地层补偿密度和用分辨率匹配技术提高补偿密度纵向分辨率二种处理技术，并结合大港油田的具体地质条件进行实际处理和分析比较。结果表明，根据实际环境条件，采用合适的处理方法提高补偿密度测井曲线的纵向分辨率是可行的。

Compensated Density is very important for the evaluation of formation porosityand lithology.Vertical resolution enhancement of compensated density log is a prerequisite for the evaluation of thin beds. Determination of compensated formationdensity with near detector count rates,which is compensated by far detectorcountrates,and resolution matching technique are used in Dagang Oil Field to enhance vertical resolution of compensated dual density log.The effects are comparedand anslysed by applying them to practice.The processing results prove that bothmethods are effective.As to which should be selected, it should depend on theborehole conditions.
