针对火山岩储层存在岩性复杂、流体多样、岩性对测井曲线的影响甚至超过了储层流体的影响等测井评价难点,以松辽盆地徐深气田火山岩储层为研究对象,综合利用测井、录井、测试和岩心分析等资料,通过储层“四性”关系的研究,采用常规测井识别岩石组分、成像测井识别岩石结构、构造,并结合ECS测井综合判别火山岩岩性,在此基础上建立了常规测井和特殊测井相结合的流体识别方法。将上述方法应用到该气田天然气探明储量的评价中,取得了良好的效果,这为其他地区类似的火山岩储层评价提供了可借鉴的经验。
In view of the complexity of volcanic reservoirs, the diversity of fluids, the influence of lithology on well logging curves even beyond the influence of reservoir fluids, and other logging evaluation difficulties, volcanic reservoirs in Xushen gas field of Songliao Basin are taken as research objects, and the comprehensive utilization Logging, logging, testing and core analysis data are used to identify the rock components by conventional logging through the study of the relationship between reservoir and quaternity. Imaging logging identifies rock structure and structure, and combined with ECS logging synthesis Discrimination of volcanic lithology, on the basis of established a conventional well logging and special logging fluid identification method. The above method has been applied to the evaluation of proved reserves of natural gas in the gas field and has achieved good results. This provides a reference for similar volcanic reservoir evaluation in other areas.
