首先介绍了元素俘获谱测井的原理,然后以准噶尔盆地腹部永进地区为例,总结了该测井方法在确定地层岩矿类型和含量,以及沉积相分析与对比方面的应用。对于常规测井解释为高伽马的地层,ECS通过定量计算粘土含量和储层矿物体积含量,准确地划分出了储层,从而发现了新油气层。应用实例表明,ECS在划分岩性和分析储层有利沉积相带方面已显示出其独特的优越性。 Firstly, the principle of elemental capture spectroscopy logging is introduced. Taking the Yongjin area in the abdomen of Junggar Basin as an example, the application of this logging method in determining stratigraphy and rock type and content, sedimentary facies analysis and comparison is summarized. For formations interpreted as high gamma by conventional logging, ECS identified the new reservoir by accurately calculating the clay content and the reservoir mineral volume content. Application examples show that ECS has shown its unique superiority in the division of lithology and the analysis of favorable sedimentary facies belt.
