摘要
目前火山岩的裂缝主要是通过岩心观察、测井曲线分析等研究方法来识别,但由于成本及准确率等原因使其作为裂缝的应用方法不够理想,并且定量识别仍然是一个难题。利用常规测井资料和成像测井资料采用多参数综合识别方法对渤海湾盆地某凹陷火山岩储层裂缝进行研究,通过参数优选、多组判别分析,建立了火山岩储层裂缝的定量识别模型,取得了较好的效果。
At present,the fracture in volcanic rock is identified mainly through core observation and well-logging curve analysis.But all of these are not ideal due to their cost and precision.Moreover,quantitative identification is still a great challenge.By using image and conventional logging data,the fracture in volcanic reservoir in some depression of Bohaiwan Basin has been studied in this paper through a comprehensive identification method of multi-parameters.A quantitative identification model of the volcanic reservoir is built through parameter optimization and multi-group discrimination analysis.A good effect is achieved and the identifying success rate is near 80 %.
