Study on Fine Interpretation Method of Water Injection Profile in Thick Beds.

分析了吸水剖面测井资料厚层细分解释的必要性 ,从放射性测井原理出发 ,阐述了厚度划分的基本理论 ,并以此为基础 ,提出了区别窜槽和邻层影响的方法。针对吸水剖面解释过程中出现的一系列问题 ,总结了一套行之有效的解决办法。厚层细分解释方法在某油田的应用效果表明 ,厚层细分解释结果真实地反映地下的实际情况 ,为油田开发提供更科学的动态资料。

The necessity of fine interpretation of water injection profile in thick beds is analysed. Based on the radioactivity well logging principle, the basic theory of how to determine the thickness of water injection zone is described. And how to identify channeling and the effect of adjacent beds is also proposed. A series of effective methods are summarized to solve the problems involved in the interpretation of water injection profile. The application result in a certain oilfield proves that the interpretation result by the method given can reflect the true subsurface situation, which provides a scientific dynamic information for oil development.
