元素俘获能谱测井在煤层气测井评价中的应用思考
|
摘要
煤层气是指储存在煤层中以甲烷为主要成分,以吸附在煤基质颗粒表面为主、部分游离于煤孔隙或溶解于煤层水中的烃类气体。煤层气测井评价要点包括煤层识别与划分、煤岩工业组分计算、煤岩物性解释、煤层气含气量计算、煤阶识别及煤岩顶底板力学特征研究等,常用的煤层气测井评价方法包括岩性测井系列、孔隙度测井系列及电阻率测井系列等。元素俘获能谱测井是近年发展起来的一种分析地层信息的测井新方法 ,能够用于复杂岩性识别、矿物含量计算、沉积环境研究、地层对比、流体性质识别、储层评价等。元素俘获能谱测井目前已用于煤层气测井评价中的岩性解释、工业组分计算和岩石脆性指数计算等方面;遵循岩心刻度测井原则,将煤岩岩石物理测试分析结果与元素俘获能谱响应相结合,可以利用元素俘获能谱测井开展更多方面的煤层气测井评价工作。
Coalbed methane(CBM) refers to the hydrocarbon gas whose main components are methane,which stored in the coal bed,mainly adsorbed at the particle surface of coal matrix,partially isolated from coal pore or dissolved in the water of the coalbed.The key of the logging evaluation on the coalbed methane includes coalbed identification and classification,commercial macerals calculation,physical property interpretation of the coal,computation of gas content of the coalbed methane,coal rank identification and mechanics characteristics study of the roof and floor.Conventional CBM logging evaluation methods involve in lithology logging series,porosity logging series and resistivity logging series,etc.Elemental capture spectral logging is a new logging method for analyzing formation information developed in recent years.It can be applied to complex lithologic identification,mineral content calculation,sedimentary environment study,stratigraphic correlation,fluid property identification,reservoir evaluation and so on.It has applied to the lithology interpretation,commercial macerals calculation and rock brittleness index calculation during the coalbed methane logging evaluation now.Followed by the principle of core calibration logging,the combination of testing results of coal physics and elemental capture spectral response may do more coalbed methane logging evaluation through the elemental capture spectral logging.
