摘要
The movable fluid evaluation was conducted based on a total of 277 matrix block samples from three typical domestic low-permeability reservoirs of different lithologies, mainly using nuclear magnetic resonance (NMR) core analysis technique of low magnetic field and supplemented by other routine test means including rock thin section, environment scanning electron microscopy (ESEM), high-resolution computed tomography (CT) and imaging logging. The results show that the movable fluid parameters of low permeability reservoirs have wide range. The relation of the movable fluid parameters and the permeability gets better with the increase of permeability.
