摘要
Shale reservoir pore diameter is distributed in the micro-nanometer scale, which is different from conventional sandstone reservoir. As a result, conventional test methods are not valid in shale reservoir. Recently, all of test methods applied in shale reservoir can be divided into two categories： （1） image analysis is observed and scaned , using various types of high resolution scanning electron microscopes （SEM）; （2） Intrusive methods are based on nitrogen adsorption method （NAM） and mercury porosimetry method （MPM）.
