Abstract
Tight oil reservoirs, characterized by low permeability and high viscosity crude oil, pose numerous challenges in their development. Water flooding huff and puff technology, as a significant oilfield development method, plays a crucial role in the development of tight oil reservoirs. This paper reviews the principles, influencing factors, application effects, and recent research progress of water flooding huff and puff technology. First, the background and challenges of tight oil reservoir development, as well as the basic principles and working mechanisms of water flooding huff and puff technology, are introduced. Next, the impact of this technology on the development of tight oil reservoirs is analyzed, including its effects on enhancing oil recovery, increasing production, and improving oil-water distribution. Then, key factors affecting the effectiveness of water flooding huff and puff are summarized, such as the timing, volume, and rate of water injection, along with geological factors. Subsequently, recent research progress in water flooding huff and puff technology for tight oil reservoir development is highlighted, encompassing experimental studies, numerical simulations, and engineering application cases. Finally, strategies for optimizing water flooding huff and puff technology are proposed, along with suggestions for future research directions. This paper aims to systematically summarize the current application status and research progress of water flooding huff and puff technology in tight oil reservoir development, providing a reference for further improving oilfield development efficiency and economic benefits.
