| 摘 要： | 以准噶尔盆地滴西地区的复杂火成岩岩性识别为例,采用层次分解法逐级分解的思想,利用测井交会图建立研究区火成岩岩性识别层次,然后依照建立的识别层次对研究区火成岩逐级识别.层次分解的原则是酸碱性差别大的岩性最先识别开,同一岩性一般不由多张交会图版分开识别,同时还要有利于下一级混合岩性的细分;在细分的过程中,若某类岩石能直接与其他岩石分解开则直接分解,不用拘泥于事先所确定的层次划分.共识别出火成岩15种、沉积岩2种;与岩心薄片鉴定资料比较,平均岩性识别符合率80.15%.凝灰岩、火山角砾岩、熔岩类之间误识几率较大,应用效果良好.

| Abstract: | It is essential to identify the lithology of igneous rocks in formation evaluation,whereas the igneous rocks include so various categories that it is hard to distinguish each of them at one time.The proposed measures in this paper may provide another effective method to identify lithology in Dixi Area in Jungger Basin.Firstly established is the hierarchy of lithologic identification by the help of cross plot,and then aligned is the sequence of identified rocks,finally recognized are the corresponding igneou... |
