摘要
测井评价在页岩气的勘探开发过程评价中发挥着至关重要的作用,与常规储层相比,页岩气储层的测井评价难度更大。经过大量的关于页岩气的文献调研,综述了页岩气的开发现状以及页岩气储层的地质特征和测井响应特征,概括性地介绍了当今页岩气测井评价的测井系列;总结了页岩气测井评价的任务主要包括矿物组分评价、物性参数评价、地化参数评价、含气量的计算、岩石力学参数的计算以及裂缝识别;给出了页岩气储层测井解释评价的技术和方法,并对页岩气测井评价提出了一些建议和认识。
Logging evaluation took an important role in shale gas exploration and development,compared with the conventional reservoir,the logging evaluation on shale gas reservoir was more difficult.Based on literature researches and investigations,the present situation of shale gas exploration,the geological and logging features of shale gas reservoirs were summarized,and the logging series used in the shale gas reservoirs was introduced.The task of logging evaluation on shale gas reservoirs included the mineral composition evaluation,the pore-permeability parameter evaluation,geochemical parameter evaluation,gas content evaluation,rock mechanical parameter calculation and the fracture recognition.The method of logging interpretation and evaluation on shale gas reservoirs are provided,some suggestions and understanding of the logging evaluation on the shale gas reservoirs are put forward.
