Numerical simulation of fractured imbibition in a shale oil reservoir based on the discrete fracture model

工程科学学报, 2022
When a shale oil reservoir contains a mass of clay minerals, the salinity of formation water can reach up to 4.786×103 mol·m−3 and the formation water and low salinity fracturing fluid create significant osmotic pressure during the fracturing process. To

Differences in Imbibition Efficiency Between Bedding and Tectonic Fractures in the Lucaogou Formation in the Jimusar Sag: Evidence From Simulation Experiments

Frontiers in Earth Science, 2022
In addition to tectonic fractures, the ubiquitous and important bedding fractures are often overlooked in the imbibition processes. Based on the identification of different fracture types in tight sandstone from the middle Permian Lucaogou Formation in ...

A Generalized Capillary Imbibition Model for Porous Media in Tight Reservoirs

Advances in Civil Engineering, 2018
Capillary imbibition models have been widely studied in oil and gas development field over the past decades. However, the existing models applied to the tight reservoirs rarely take fluid flow resistance and apparent viscosity into account.

Investigation of smoothed particle hydrodynamics (SPH) method for modeling of two-phase flow through porous medium: application for drainage and imbibition processes

Scientific Reports
The drainage and imbibition processes are critical mechanisms in petroleum engineering. These processes in a porous medium are controlled by surface forces and pressure gradients. The study of these processes in the pore scale by common simulators always
