摘　　要：辽河GS油田主力储层为沙三段莲花油层,油层由阵发性浊积砂岩构成,具有较强的非均质性。受非均质性的影响,基于常规测井体积模型和阿尔奇公式的一次解释结果误差较大,因而需要进行二次解释为油田开发提供可靠依据。以辽河GS油田为例详细讨论了非均质储层测井二次解释中的3项关键技术,即趋势面法标准化处理、"四性"关系分析和解释模板确定,总结了一套非均质性储层测井二次解释的方法,对该油田60余口井进行了二次解释,经试油检验符合度达到83%,证实该方法具有一定的推广前景。Lianhua oil-bearing horizons (Es3) in Liaohe Oilfield were consisted of spasmodic turbidite sequences and the reservoir units showed strong heterogeneities.Due to the heterogeneities of reservoirs,the interpretation results by conventional logging model and Archie formula were often difference in practice,of which secondary interpretation was required to satisfy the needs of reservoir exploration.Liaohe GS Oilfield was used as an example to discuss in detail to explain technical factors of the secondary logging interpretation,that is,the trend of surface standardized process,correction,analysis of 'four characters' were analyzed and reservoir parameters,a chartboard was established.A set of methods for the secondary logging interpretation were set up and applied in 60 wells of Liaohe GS Oilfield with coincidence rate of 83%.The practical application shows the method is efficiency and is worthy of field application.
