摘要
页岩气藏一般发育在暗色泥页岩、高碳泥页岩及其间所夹砂质、粉砂质岩类地层中,页岩气储层识别与划分以及矿物组分计算,是页岩气储层测井评价中的关键内容。目前国内外页岩气储层测井评价中,一般采用常规测井、元素俘获能谱测井(ECS)、自然伽马能谱测井(NGS)和岩性密度测井等资料来计算页岩的矿物组分。它们不仅为页岩气储层矿物组分问题的解决提供了有效手段,而且对我国页岩气的勘探开发具有一定的借鉴作用。
The shale gas generally develops in dark shale, high--carbon shale, the sandy and silty rock. Distinguishing and dividing the shale gas reservoirs as well as calculating the mineralogical composition are the committed points of the logging evaluation of shale gas reservoirs. At the present time, the data such as conventional logging, elemental capture spectroscopy logging （ECS）, natural gamma--ray spectral logging （NGS） and litho--density logging have been used often to calculate the mineralogical composition of shale in the evaluation methodology of the shale gas reservoirs at home and abroad. These not only provide an effective method for resolving the problem of the mineralogical composition of the shale gas reservoirs, but also provide a reference for the exploration and exploitation of shale gas in China.
