PNN测井在完井资料缺失评价中的应用

The application of PNN log to well evaluation without openhole log data

文章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PNN测井资料进行评价的方法。可以根据PNN测得的曲线资料建立泥质含量、孔隙度和饱和度等参数模型,应用所建模型并结合其它地质数据,对某区块井进行储层综合评价。并根据求得的数据进行射孔、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。

Without openhole log data,some wells can not be put into production.In this article,a new method is provided to evaluate this kind of well with PNN logging data.Based on PNN logging data,a model is built and validated to compute log interpretation parameters such as shale volume,porosity and saturation.Based on the model and other geological data,integrated interpretation such as saturation evaluation is 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.
