用DST资料评价油井污染的新方法及其应用

A New Approach to Evaluate Well Damage Using DST Data and It’s Application

本文探讨了用DST资料评价油井污染系数的新方法,并将新方法编制成了计算机软件。运用该软件对华北油田五十多井次的DST资料进行了分析,得出了与油井实际情况相符合的结果,将该结果与传统的分析处理方法的结果进行了对比,明显的可以看出,木文方法具有分析结果合理、能反应油井真实污染情况之特点,为油气井的增产措施决策提供了科学依据。

This paper discusses a new,approach to evaluate well damage using DST data. A computer software was compiled using this new approach. With this software, over 50 runs of DST data from Huabei Oilfield were analysed,With the results corresponding to actual well conditions. Comparison of these results with the results obtained from conventional evaluation approach clearly showed that,whh the features of reasonableness of analysis results and reflection to actual well damage conditions,the approach presented in this paper will provide scientific basis for decision on well stimulations.
