| Abstract: | Spontaneous capillary imbibition displacement is an important recovery mechanism for low permeability fractured oil reservoirs.The analysis of influence factors of imbibition and the study of reservoir imbibition potential should be of good significance for the effective use of imbibition effect and promotion of reservoir recovery rate.In this work,the reservoir imbibition and imbibition coefficient are analyzed systematically.Based on the fractal properties of pore structure of reservoir rocks,the relation... |
