摘　　要：针对火山岩裂缝性油气藏裂缝测井识别这一难题,在详细定义了火山岩储层裂缝的指标的基础上,建立了综合裂缝概率模型。利用该模型对西部火山岩储层进行了裂缝定量识别,识别结果与成像测井对比表明,综合概率法能够较准确地对火山岩的裂缝进行识别,且精度较高、实用性强,能满足火山岩地层裂缝测井识别精度的要求。Targeting at the difficult problems of fracture logging identification for volcanic fractured reservoirs,a synthetic fracture probability model has been built based on detailed definition of fracture indexes of the volcanic reservoir.The fracture of the volcanic reservoir in West China has been quantitatively identified using the model.The correlation between the identifying results and the image logging shows that this synthetic probability method,with a very strong practicality,can not only precisely identify volcanic rock fracture but also meet precision demand in fracture logging identification of volcanic rock formation.
