由于气层、水层层段上物性的复杂性,导致测井曲线特征复杂,利用测井曲线直接识别油气层的效果不好,有可能造成误判或错判,为此,提取一些特征参数,建立识别气层、水层的判别函数,来提高识别的准确率。本文对气层、水层的测井响应进行分析,提取气层、水层的测井曲线特征参数,利用模糊模式识别渗透层,奇异值分解方法建立判别函数,最后利用判别函数来识别油(气)层、气水同层、水层和干层,实际解释结果表明,取得了符合率高的效果。
Due to the complexity of the physical properties in the layers of the gas and water layers, the logging curves are complicated in character and the logging curve is used to directly identify the oil and gas layers, which may lead to misjudgment or misjudgment. Therefore, some characteristic parameters , To establish identification of gas and water discriminant functions to improve the recognition accuracy. In this paper, we analyze the logging response of gas and water layers, extract the logging curve characteristic parameters of gas and water layers, establish discriminant function by using fuzzy pattern recognition permeation layer and singular value decomposition method, and finally use discriminant function to identify oil Gas) layer, gas and water in the same layer, water layer and dry layer, the actual interpretation results show that achieved high results.
