Wax　deposition　in　wells　and　long-distance　pipelines　is　a　significant　issue,　leading　to　a　reduced　flow　area,　increased　system　pressure,　and　higher　flow　resistance.　In　extreme　cases,　it　can　cause　complete　pipeline　blockage,　posing　serious　risks　to　crude　oil　production　and　transportation.　As　a　result,　wax　deposition　has　long　been　a　central　focus　of　petroleum　research,　particularly　the　radial　characteristics　of　wax　deposits.　This　paper　provides　a　comprehensive　review　of　the　latest　research　on　the　radial　properties　of　wax　deposits,　focusing　on　key　aspects　such　as　influencing　mechanisms,　experimental　setups,　sampling　methods,　physicochemical　property　variations,　and　predictive　models.　It　systematically　evaluates　the　primary　technical　approaches　and　findings　in　this　field,　highlighting　key　achievements,　current　challenges,　and　potential　future　research　focuses.　This　review　aims　to　offer　readers　a　clear　understanding　of　the　methodologies　employed,　common　challenges,　established　conclusions,　and　ongoing　debates　while　providing　valuable　insights　for　advancing　research　on　the　radial　properties　of　wax　deposits.　©　2025　American　Chemical　Society.
