Abstract A multitechnique characterization approach has been used to quantitatively and qualitatively evaluate all the reservoir quality parameters, crucial for the exploitation and development of unconventional shale plays. Characterization methods, in particular FTIR, XRF, NMR, MICP, HPP, LPP and High Pressure Permeameter were used on selected 20 younger and older shale samples of Cambay to determine their true petrophysics, mineralogy, brittleness and fracability potential with respect to depth. Properties mainly porosity, permeability, pore size distribution, mineralogy, brittleness, pore sizes and fracability were determined. It was found that younger cambay has medium size pores with high porosity, low silica and high clay content. On the contrary, older cambay has good pore connectivity, rich in organic and clay content, fair brittleness index and capable of producing hydrocarbons. The performed multidisciplinary analysis is first of its kind research and will go a long way in shale gas research and development in India at pilot scale. The generated data can be helpful in minimizing the research gap and hence the challenges associated with the commercial development of these prolific shales.

页岩储层质量参数的多技术表征

摘要 采用多技术表征方法对所有储层质量参数进行定量和定性评价，这对非常规页岩油藏的开发和开发至关重要。表征方法，特别是 FTIR、XRF、NMR、MICP、HPP、LPP 和高压渗透仪被用于 Cambay 选定的 20 个较年轻和较老的页岩样品，以确定它们在深度方面的真实岩石物理、矿物学、脆性和可压裂性潜力。主要测定了孔隙率、渗透率、孔径分布、矿物学、脆性、孔径和可压裂性等性质。发现年轻的坎贝具有中等大小的孔隙，孔隙率高，二氧化硅含量低，粘土含量高。相反，老cambay具有良好的孔隙连通性，有机质和粘土含量丰富，脆性指数一般，能生产碳氢化合物。所进行的多学科分析是同类研究中的首创，将在印度的中试规模页岩气研发中大有作为。生成的数据有助于最大限度地减少研究差距，从而减少与这些多产页岩的商业开发相关的挑战。
