EXPERIMENTAL STUDY ON POST-FRACTURE OIL-WATER DISPLACEMENT MECHANISM OF TIGHT SANDSTONE RESERVOIR WITH NUCLEAR MAGNETIC RESONANCE

ABSTRACT
In this paper, three different fracturing fluids are used as replacement working fluids, and nuclear magnetic resonance technology is used to study the oil-water replacement law of tight sandstone cores in the field, revealing the main influencing factors of oil-water replacement in the process of tight oil fracturing flow back.
