摘　　要：针对一些井因完井资料缺失而无法进行正常开发利用的问题,提出利用双源距碳氧比测井资料进行评价的方法。用双源距碳氧比测井曲线建立孔隙度和泥质含量等参数求取模型,并对所建模型进行验证。应用所建模型并结合其他地质数据,对某区块该类井进行了储层划分及饱和度的求取等综合评价。采油厂根据解释结果进行射孔、试油验证。从射孔试油的结果看,提出的方法在现场实际应用中是可行的。Some wells can not be put into production as normal because of no openhole log data. Provided is a method to evaluate this kind of well with dual-spaced C/O logging data. Based on present dual-spaced C/O logging data, a model is built and validated to compute log interpretation parameters such as porosity and shale volume. By utilizing the model and other geological data, integrated interpretation such as reservoir zonation, saturation evaluation are made for wells without openhole log data. According to the evaluation results, the oil production company performs perforating and oil testing. It proves that the method mentioned above has a better effect in field log application.
