An integrated pore size distribution measurement method of small angle neutron scattering and mercury intrusion capillary pressure

Abstract Small-angle neutron scattering and high-pressure mercury intrusion capillary pressure testing are integrated to analyze the pore size distribution of the broad sense shale oil reservoir samples of the Permian Lucaogou Formation in the Jimsar Sag, Junggar Basin, China. The results show that,...
