| 摘 要： | 提出了一种基于非线性最小二乘法的双感应测井反演方法,并将其应用于莺歌海盆地乐东和东方地区共8口井的资料处理中。利用阵列感应测井数据对该方法的处理结果进行了验证,并由处理结果分析认为,乐东地区厚层低阻气层主要是由岩性造成的,薄层低阻气层则主要是由层厚造成的;而东方地区厚层低阻气层主要是由岩性和侵入造成的,薄层低阻气层则主要是由层厚和侵入造成的。

| Abstract: | A dual induction log inversion method, which is based on the nonlinear least squares algorithm, has been used in log data processing for 8 wells in Ledong and Dongfang areas, Yinggehai basin. Array induction logs can be used to check the processing results of the method, and the following conclusions can be given: (1) In Ledong area, the thick gas reservoirs with low resistivity are mainly controlled by lithology, and the thin reservoirs with low resistivity are mainly controlled by bed thickness; (2) In Dongfang area, the thick reservoirs are mainly related to lithology and intrusions, and the thin reservoirs are mainly related to bed thickness and intrusions. |
