低阻油层识别方法研究
A Study on Low Resistivity Reservoir Identification Methods
-
摘要: 通过双河油田上倾尖灭区低胆油层的研究,探讨了多种识别低阻油层的方法。提出了“概念识别-φ-Sw图版识别-BAYES多组判别、神经网络模式识别”这样一套由简单到复杂,多层次、多种数学手段相互补充的识别方法,使该区低阻油层的解释符合率达到80%以上,也为评价和识别同类油层提供了方法和依据。Abstract: On the basis of study of the low resistivity reservoirs in Shuanghe oilfield, this paper presents a suit of multilevel identification methods which includes"conceptual identification - φ - Sw chart board identification - BAYES multigroup discrimination - neural network mode identification".The interpretation coincidence rate of thlow resistivity reservoirs in this oil field reaches 80% by use of these methods.
