THE IMPACT OF WATER INJECTION-INDUCED FRACTURES ON RESIDUAL OIL DISTRIBUTION IN TIGHT SANDSTONE RESERVOIRS

ABSTRACT
This study conducted water-induced fracture experiments and full-diameter core displacement experiments on the cores of a certain oil reservoir in the Ordos Basin, aiming to investigate the impact of these induced fractures of different sizes on displacement efficiency and the distribution of remaining oil, and to perform quantitative analysis. The experimental results indicate that the oil displacement efficiency of the core is related to the depth, angle, and complexity of full-diameter core fractures.
