页岩气储层测井解释评价技术方法分析
|
摘要
掌握页岩气储层测井评价要点对评价页岩气很有必要。通过梳理页岩气储层特征、测井响应特征和评价要点,分析研究了页岩储层参数测井计算方法。结果表明,页岩气储层测井响应特征主要表现为"四高三低一扩"的特征;页岩气储层评价要点主要包括矿物组分含量计算、地化参数计算、物性参数计算、含气量计算及岩石力学参数计算等。不同研究区页岩储层特征不同,在开展页岩气测井评价时,需要以实际岩心数据为基础,选择及建立合理的储层参数测井解释模型来开展页岩气储层测井综合评价。
It is necessary to grasp the key points of logging evaluation for shale gas reservoirs. Based on the analysis of shale gas reservoir characteristics,logging response characteristics and evaluation points,the logging calculation method of shale reservoir parameters is discussed. The research shows that the logging response characteristics of shale gas reservoirs are mainly characterized by"four high,three low and one expansion",and the evaluation points of shale gas reservoirs mainly include mineral component content calculation,geochemical parameter calculation,physical parameter calculation,gas content calculation and rock mechanics parameter calculation. Because of the different characteristics of shale reservoirs in different research areas,it is necessary to select and establish reasonable logging interpretation models for comprehensive evaluation of shale gas reservoirs based on actual core data.
