利用取心分析数据提高元素俘获测井矿物含量解释精度
Improving Interpretation Accuracy of ECS Mineral Content with Core Analysis Data
摘要
Abstract
The complex mineral composition brings a great difficulty to the identification of logging lithological and calculation of mineral content. Handling of elemental capture spectroscopy log data can effectively solve the problem of complex mineral composition and content.But in the data interpretation,the conversion coefficient between elements and minerals is not the same.In different regions and horizon,the conversion coefficient is quite different.A new model of oxide closure is proposed by using X diffraction fluorescence and X diffraction analysis data of whole rocks.Solving linear equations with least square method and generalized inverse matrix help measure and get the representative coefficient of conversion between minerals and elements in the area,and process the actual data with this conversion coefficient.Comparing the processing results with Schlumberger experience conversion coefficients,it is found the conversion coefficient optimized by core experimental data can improve the accuracy of elemental capture spectroscopy log data.It provides a new way for the effective use of elemental capture spectroscopy log data in this area.关键词
