摘要:

针对火成岩岩性与岩石成分、结构、构造和成因有关,岩石类型多,识别难度大的问题,以准噶尔盆地六九区石炭系火成岩为研究对象,利用常规测井资料中所蕴藏的丰富的岩性信息,从多个方面提供了识别火成岩岩性的资料,优选出自然伽马、声波、电阻率、密度、中子等测井参数。在建立了测井相—岩相统计模式之后,利用灰色关联方法对研究工区的火成岩岩性进行识别。识别结果表明,该法能够较准确地对该工区的岩性进行识别,识别率可达90%以上。

Abstract:

According to the igneour rock lithology being related to the components,structure,texture and the origin of formation,as well as variety of rock types and the difficulty in identification,the carboneous igneous rocks in the 69th area,Junggar Basin,are taken as example to set up the data base for identifying igneous rocks by using the rich lithologic infrmation in common well logging data.The logging parameters,such as nature gamma,acoustic wave,resistivity,density and neutron,are optimized to identify igneous rock lithology according to grey connection method after the statistical model of well logging facies and lithofacies is set up.The result indicates that the method can well identify lithology in the area,the correct rate is as high as 90% or above.

Key words: Junggar Basin, 69 Area, igneous rock, lithological identification, grey connection, well logging facies
