文章以中原油田油井为研究对象,应用模糊识别理论的基本原理,采用测井数据中自然伽玛、深浅电阻率比值等7个不同权重的基本储层参数,建立样区内油层和水层模型,通过对该区域内4口井8个层段的重新解释以及试油验证,证实了模糊识别模型的有效性,指出了建立模糊识别模型必须充分考虑样本数据的特征代表性与合理选定阈定值的必要性。
Based on the basic principle of fuzzy recognition theory and using seven basic reservoir parameters with different weights, such as natural gamma ray and resistivity ratio between depth and depth, the paper sets up the oil and gas reservoir model in Zhongyuan Oilfield Through the reinterpretation of 8 intervals of 4 wells in this area and the verification of test oil, the validity of the fuzzy recognition model is verified. It is pointed out that the fuzzy identification model must fully consider the representativeness of the sample data and the reasonable selection threshold Necessity of setting value.
