This paper aims to comprehensively review and assess the research advancements in low salinity water flooding technology within the context of oilfield development. The efficacy of low salinity water flooding in substantially enhancing oil recovery through the manipulation of rock wettability and alteration of oil-water interactions has been empirically demonstrated. In recent years, investigators have delved into pivotal facets such as wettability mechanisms, repercussions of water quality, and interactions between groundwater and rock formations, among others. These endeavors have laid the groundwork for grasping the technology’s nuances and potential applications. The continuous evolution of experimental investigations and numerical simulation techniques has validated the efficacy of low salinity water flooding in boosting yields. Simultaneously, environmental considerations are gradually assuming paramount importance in research pursuits. However, an in-depth exploration of the underlying mechanisms remains indispensable, and a more comprehensive study of the displacement effects in multi-component crude oils is warranted. Concurrently, optimizing the impact and sustainability of low salinity water flooding calls for the amalgamation of intelligent management practices and environmentally sound techniques. Low salinity water flooding technology holds significant promise in the realm of oilfield development. Future research imperatives should center on untangling these pivotal quandaries, thereby propelling the pragmatic implementation and sustainable evolution of this technology.
