Organoporosity Evaluation of Shale:A Case Study of the Lower Silurian Longmaxi Shale in Southeast Chongqing

摘要

1 Introduction Petrological characteristics(such as brittle mineral content),micro-nanoscale porosity,total organic carbon and organic matter maturity of shale play important roles in the accumulation and exploration of shale gas.The nanometre pores in shale are mostly organopores(pores within organic matters in shale)created from
