摘　　要：由于火山岩储层岩性多样、非均质性强、油气藏类型复杂,导致了储量评价难度大,故储量参数的准确计算至关重要。针对火山岩骨架参数不确定的特殊性,综合岩心、薄片、元素分析和测井等资料,采取了组分与结构识别相结合、常规测井和特殊测井相结合的岩性识别思路,应用多种方法开展了火山岩的岩性测井识别研究,在岩性识别的基础上应用岩心分析、测井资料和试气成果建立了松辽盆地徐深气田储量参数计算模型,最后再用综合分析的方法进行取值,降低了储量计算的风险。使用该方法,火山岩岩性识别符合率在85%以上,储量参数精度超过80%,能够满足储量规范要求,对火山岩油气藏储量评价具有指导意义。Due to the characteristics of lithologic diversities,strong heterogeneity and complex reservoir types of volcanic reservoirs,there are great difficulties in the reserves estimates.Hence,the accurate calculation of reserves parameters is important.In view of the uncertainty of volcanic framc parameters,through comprehensive analysis of cores,flakes,elements and logging data,the researches of volcanic lithology logging identification have been carried out by adopting many methods and with the thoughts of combining the composition with the structure and the conventional logging with the specific logging.The reserves parameters calculation model for the Xushen gas field in the Songliao Basin has been established through core analysis,logging data and gas testing results based on lithology identification,and then the values were taken by the comprehensive analysis method to reduce the risk of reserves calculation.With this method,the coincidence rate for volcanic lithology identification reached up to more than 85%,with the accuracy ratio of reserves parameters calculation over 80%,which can meet the reserves specification requirements,and thus will provide reference for the reserves evaluation of the volcanic oil and gas reservoirs.
