复兴地区侏罗系陆相有利页岩气测响应特征与评价

Evaluation and Characteristics of Gas Logging Responses to Favorable Terrestrial Shale Gas in the Jurassic Period of the Fuxing Area

四川盆地复兴地区拔山寺向斜侏罗系录井现场评价难度较大。通过对气测烃类组分差异性分析,明确复兴区块侏罗系陆相有利页岩凝析油气储层气测响应特征,进一步选取测录井评价敏感参数,构建测录井解释评价标准,在实践中取得良好的应用效果,可为其他陆相区块凝析油气储层评价提供有益借鉴。

The on-site mud logging evaluation of Jurassic formations in the Bashansi Incline of the Fuxing area in the Sichuan Basin presents considerable challenges.By analyzing the differences in hydrocarbon components detected through gas logging,definite logging response characteristics for the favorable terrestrial shale condensate reservoirs in the Jurassic Fuxing area were determined.Further selection of sensitive parameters for logging evaluation led to the establishment of well logging interpretation and evaluation standards.These have been successfully applied in practice,providing a beneficial reference for the evaluation of condensate reservoirs in other terrestrial areas.
