摘要
准噶尔盆地火山岩,具有岩性多样、岩石构造复杂的特点。常规测井和元素测井资料识别火山岩的结构及构造具有一定局限性,地层微电阻率成像测井具有较高的分辨率,能直观显示井壁地层的微细变化,是识别火山岩岩石结构和构造的重要手段。通过“地质标定测井,岩心刻度图像”的方式,识别了准噶尔盆地发育的火山岩岩石构造的类型,介绍所识别的岩石构造特征,建立了火山岩岩石构造识别图版,对准噶尔盆地火山岩的岩性准确识别、岩相的划分、储层精细评价具有指导意义。
Volcanic rocks in Junggar Basin are characterized by diverse lithology and complex rock structure.Identification of the structure and structure of volcanic rocks has certain limitations to the conventional,and the formation microresistivity imaging logging has a high resolution,which can directly show the fine changes of the well wall strata,and is an important means to identify the structure and structure of volcanic rocks.Through"geological calibration logging,core scale image",identified the type,the development of the junggar basin volcanic rock structure,introduced the identified rock structure characteristics,rock structure identification plate,established the volcanic rock lithology of the junggar basin volcanic rock accurate identification,the division of the facies,reservoir fine evaluation has guiding significance.
