摘要：
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.
