印度作为亚洲少数几个发现了页岩气的国家之一,有着较大的资源潜力。据 EIA 估算,印度页岩气原地总储量为8.3×1012m3,可采储量为1.8×1012 m3。页岩气勘探工作主要分为六个步骤,其中尤为注重地球化学、地球物理和力学性质的研究。干酪根成熟度的确定主要采用镜质体反射率与声波时差的经验关系计算, TOC值的计算综合运用干酪根体积法、电阻率-孔隙度交会法,核磁共振和密度测井相结合的方法。
印度作為亞洲少數幾箇髮現瞭頁巖氣的國傢之一,有著較大的資源潛力。據 EIA 估算,印度頁巖氣原地總儲量為8.3×1012m3,可採儲量為1.8×1012 m3。頁巖氣勘探工作主要分為六箇步驟,其中尤為註重地毬化學、地毬物理和力學性質的研究。榦酪根成熟度的確定主要採用鏡質體反射率與聲波時差的經驗關繫計算, TOC值的計算綜閤運用榦酪根體積法、電阻率-孔隙度交會法,覈磁共振和密度測井相結閤的方法。

India is one of the countries rich in shale gas in Asia, with great potential of shale gas resources. According to EIA, its gas-in-place reserve is up to 8.3×1012m3 with recoverable reserve of 1.8×1012 m3. Its exploration is divided into 6 steps with special emphasis on geochemical, geophysical and mechanical studies. Maturity is computed by the empirical relationship between Ro and acoustic. And TOC value is calculated by means of the volume of kerogen, resistivity-porosity overlay technique and NMR data in combination with density logging.
