三塘湖盆地火山岩储层测井识别及评价方法

针对三塘湖盆地火山岩储层特殊性，研究了形成优质储层的主控因素，分析了岩性特征、岩相分布、溶蚀强度，以及构造裂缝发育程度等因素给测井解释评价带来的影响，结合常规测井、偶极子声波测井、自然伽玛能谱和电成像测井等资料，形成了一套火山岩储层测井综合识别方法，建立了不同构造部位的测井解释标准。这套方法和标准在牛东地区调整井测井解释中应用效果较好。

LOGGING IDENTIFICATION AND EVALUATION METHOD OF VOLCANIC RESERVOIR IN SANTANGHU BASIN

According to the specialist of the volcanic reservoirs in Santanghu Basin,we studied the main control factors to form a good reservoir,analysed the affection of many factors to logging interpretation and evaluation,such as the lithologic features,face changes,intensity degree of the chemical erosion and developmental degree of the tectonic fissures.Combining with conventional logging data,dipole acoustic logging data,NGS and FMI information,we established a series of logging identification methods of volcanic reservoirs and built up different logging interpretational criterions to different structural location.And the logging interpretation in the adjustment well in NiuDong block shows that the method and criteria are quite good.
