摘要
裂缝性油气藏研究中,裂缝识别一直是测井解释的难点。在详细对比分析了准噶尔盆地六九区火山岩的成像测井和常规测井响应特征之后,给出了4种测井裂缝指标,进而建立了火山岩裂缝识别模型。并将此模型程序化,实现了裂缝的计算机自动识别。识别结果与成像测井对比表明,该法能够较准确地对研究区火山岩裂缝进行识别。
During research of fractured reservoir,it is always difficult to recognize the fractures in well log interpretation.After detailed analyzing and correlating the response characteristics of 6 and 9 area volcanic rock in Zhungaer basin based on FMI and conventional logging,four kinds of oil well logging fracture indexes have been given,and the volcanic rock fracture recognition model has been established.The model is programmed,so the fractures can be diagnosed automatically by computer.The recognition result indicates that the above method may accurately recognize the fractures in the researched area compared with FMI data.
