Low-permeability reservoirs have tiny pores with winding and complicated pore throats.

The oil recovery efficiency of low-permeability reservoirs can be enhanced through the displacement of reservoir oil through imbibition.

In the present study, experiments were conducted to investigate variations in the imbibition height of hydrophilic and weakly-hydrophilic rock samples under different interfacial tensions.

An imbibition model considering imbibition resistance and bending of pore throats was established based on fractal theory.

According to the experimental results, variations in the imbibition height of low-permeability rock samples with time can be divided into three stages.

In the first stage, the capillary force plays a dominant role, while the viscous force and gravity have very slight effects.

The imbibition height first increases rapidly and then levels off to a constant rate.

With the increase in interfacial tension, the imbibition rate in the first stage increases, the ultimate imbibition height increases initially and then decreases, and the contribution of the imbibition height in the first stage to the ultimate imbibition height becomes greater.

There is an optimal interfacial tension that causes the ultimate imbibition height to reach its maximum.

The calculated results obtained from the proposed imbibition model are consistent with the experimental results, indicating that the model can accurately reflect the change in the imbibition height in low-permeability reservoirs in the first stage.
