| 摘 要： | 泥岩是沉积盆地的主要组成部分，但由于样品保存性差、黏土矿物膨胀与收缩、颗粒细小，对于泥岩性质的认识并不深入。而弄清楚泥岩的性质有利于解决目前油气勘探所面临的一系列难题，如钻井稳定性、超压风险、泥岩各向异性、泥岩岩石力学性质、物理特征及测井响应等。特别是在页岩气勘探过程中，对泥页岩的性质也需要有更多的认识。目前国内外泥岩性质研究与盖层评价技术已取得一系列进展。

| Abstract: | Shales form a large proportion of sedimentary basin fill worldwide and they have not been studied in great detail to date due to the lack of preserved specimens, clay mineral dilation and shrinkage, small granular, timing taken to perform tests. Understanding shale behavior is critical to a range of issues confronting petroleum industry, such as wellbore stability, top seal, predicting overpressure for low-permeability shale, understanding the effects of anisotropy on depth conversion, shale mechanics and petrophysical response on logs. It is also necessary for the exploration of shale gas. A series of progress has been made in shale research and seal appraisal at home and abroad. |
