Tight reservoirs are rich in microscale pores, and the fluid flow mechanisms are extremely complex. In this paper, firstly, by using the high-temperature and high-pressure static and dynamic throughput experimental equipment and nuclear magnetic resonance instrument, the effects of pressure and imbi...
